Sewing Machine Motor

What do you think is the most important part of a sewing machine?

Sewing area? Nope. bobbin loading mechanism? Nah. Running speed or display options? Certainly not. Automation? Please stop!

None of these features form the most important aspect of a machine.

Then what is it, I hear you ask?

It’s the sewing machine motor. Controlled with the presser-foot, the motor is the heart of the machine which provides enough impetus to other parts to keep them running.

But what if it stops running?

Well, then all hell has broken loose. Not only will you won’t be able to move forward with your work but you’ll also have to repair or worse, replace the motor. And as you might guess, none of these too tasks come inexpensively.

Hence, the next time you go search for your ideal sewing machine, you may want to pay maximum attention to its motor type.

Types of Sewing Machine Motors

In the sewing industry, two types of motors are more commonly used: the Clutch Motor and the Servo Motor. As you might guess, each of these types offers unique qualities that meet a varying set of needs. More importantly, both them run differently and that is where the first difference between them comes into play.

Clutch Motor

Have grown tired of the incessant noise coming out of your machine, even when you are not engaging it? Well, it seems that you’ve been using a clutch motor.

For, unlike servo machines which operate only when you press the pedal, clutch motors can operate round the clock provided the machine is on. Hence the noise factor which clutch motors emit consistently while servo motors did so intermittently.

Pros

Despite this obvious noise problem, it was, and continues to be, the workhorse of the industry. For, when it comes to sheer power and reliability, such motors are unrivalled.

The most important aspect of the Clutch motor is the power it oozes out. Since you can tinker with its RPMs and HP, machines carrying clutch motors are able to handle heavier materials and heavier workloads.

Clutch motors are generally available in 3450RPM and 1725RPM and 1/2HP or 3/4HP. It is suggested that if you are sewing a material whose thickness approaches or exceeds?”, use a 3/4HP clutch motor to get better punching power than a servo motor.

Cons

On the flip side, they are not to be used when precision is your goal. They are only suitable for sewing heavy materials such as leashes, harnesses and other thick materials. For leather jackets, upholstery work or clothing – or any other project which would require you to move forward slowly and precisely, go for the Servo Motor.

Servo Motor

As stated above, servo motors only run when they are engaged with the pedal. Consequently, the amount of heat they generate is almost negligible. If you are using a Servo machine in a commercial setting, the low heat generation will result in the reduction of cooling costs and the creation of a comfortable working environment for the sewer.

Pros

Additionally, since they operate at reduced power, vibration produced by Servo machines is almost negligible. This leads to a better stitch quality and a longer working life of the machine.

When you are creating unique designs and stitches, it is suggested to engage a Servo machine. For, thanks to their ease of operation, they make such tasks less complication and result in a reduced number of stitching mistakes.

Why? Well, they operate at a constant speed and obviously the sewer knows that. As a result, no matter how much the workload, the sewer feels that the speed of his machine is under his control. Consequently, he is better placed to navigate intricate stitching patterns with more ease than a clutch motor.

Finally, in stark contrast to a long held belief, you CAN use servo machines for handling heavier tasks. However, for you to do that, experience in the field is a must.

Cons

Although it is true that Servo machines can handle both heavy and light tasks with ease, their area of expertise lies with the lighter tasks. Hence, if your work involves stitching only heavy fabrics, you may need the extra power provided by Clutch machine.

Which One Should You Choose?

If you are preparing yourself to hit the gate running, have been in this field for decades and are sewing mainly heavy fabrics, you need a clutch motor. End of story.

At the same time, if you are a beginner or a veteran willing to learn more designs or want to sew detailed stitches – a task which requires slow speed, go for the Servo Motor. With the advent of technology, Servo rivals Clutch motor in the punching power, meaning it can be suitable for almost any type of work.

Finally, both these motors have the ability to get the job end of the day. However, depending on the level of your experience and the type of fabric, one might take more time and work than the other. Still, both will get the job done.

How to Replace The Sewing Machine Motor?

Since you are looking for a new motor, it means that either the old one has gone rogue or you have grown tired of its habits. Regardless of your reason, you can replace it on your own with little effort. Provided you are willing to follow the abovementioned steps to the letter, the whole process of replacing the motor shouldn’t take more than 30minutes.

Tools Required

Philips Screwdriver, Work gloves

Steps

  1. Wear work gloves

Even after you have turned off the electricity, it is advised not to take off the work gloves as they will save your hands from getting dirty.

  1. Turn off the electricity

Do NOT just rely on turning off the switch where the power cord is plugged. You might still be in harm’s way. Rather, unplug the power cord from the outlet where it is mounted.

  1. Remove belt drive cover

With the help of the Philips screwdriver, remove the screws which secure the belt drive cover against the sewing machine. There will be two screws: one at the front and the other at the bottom of the machine. Afterward, take the belt cover off.

  1. Take out the Drive Belt

There will be two screws securing the drive belt against the motor. Loosen both, and tilt the motor upward. In this way, you’d be releasing the tension on the belt. Finally, after you have slided the drive belt off its hand wheel, remove it.

  1. Take out the driver motor

Once again, remove the two screws that are mounting the motor against the machine, before sliding the latter out. Now, there will be a terminal block, remove it as well. Finally, after you have disconnected the terminal block from the motor wires, remove the motor.

  1. Install your brand new motor

Do the previous four steps in reverse. First, you’ll have to reconnect the motor wires to their terminal block. Next, secure the terminal block as well as the screws.

Finally, it is time you place the new motor at exactly the same position on the machine from where you removed the previous, faulty motor, before loosely securing the motor with its mounting screws.

  1. Restore the drive motor to its original position

After you’ve positioned the drive belt underneath the motor pulley, gently move the drive belt over and onto the hand wheel. To reapply tension, slightly pivot the drive motor before tightening the screws around it firmly.

  1. Reconnect the belt cover

This is step 2 in reverse. All you have to do is to position the belt cover against the machine in such a way that the positions of both the screws become visible, before securing the screws.

Congrats! You have replaced your sewing machine motor.

Enduro Advantage 110-Volt Single Phase Servo Motor

There are so many motors in the market that you don’t know which to trust. However, in Enduro, you have a brand which has a history of customer satisfaction which you can trust with blind eyes. Still, it is NOT the history of Enduro but the features which forced us to include it on our list.

Features

In breaking away with tradition, Enduro has gone for brushless DC motor in the Enduro Advantage. This is a surprise given the fact that most manufacturers still develop brushed motors considering their omnipotence and their popularity among the consumers.

Still, by opting for a brushless motor, Enduro has been able to tap up benefits which brushed motors can only dream of. First, and the most obvious advantage comes from the fact that there are no brushes at play here. It means that with fewer moving parts at play, there are fewer chances of anything breaking or wearing out.

A brushless motor operates with less noise because all of its parts are totally enclosed. As a result, little noise comes out of whatever is happening inside the device. Finally, the lack of moving parts allows the brushless motors to create a reduced electromagnetic interference (EMI).

Another benefit you’ll get by using this unit is to adjust its speed. Yes, provided you have just started and not quite in the mood, you can set the machine to rev at slow speeds. Once you find your rhythm, you can allow it to operate at full speed.

Conversely, if you feel that the workload on any particular day is more than normal, you can set itto start at a higher accelerating speed. In this way, you’d save the time which other, cheap motors take in getting warmed up.

Safety is yet another feature of this motor which needs your attention. Whenever it detects any interruption such as electrical surge or in-line voltage, it will automatically stop, hence preventing burns. What’s more, this motor has a software generating and displaying error messages, hence telling you where the fault lies.

Pros

  • Brilliant safety features
  • No noise and EMI
  • Able to run in both normal and reverse direction
  • Has the ability to start at different speeds

Cons

  • Expensive

Final Verdict

If your industrial sewing machine’s motor needs replacement – and you won’t try to use the same motor again, the Enduro Advantage 110-Volt deserves your attention.

Will it suit your needs? Let’s find out.

Features

How light it is! It was the first thought which came to my mind after I grudgingly picked up it for a closer look. On checking its specs, I found out that it weighs only 5kgs, making it one of the most lightweight the market has to offer.

Once you have installed this motor, you won’t have to look at its manual time and again for directions. You can use buttons on the motor casing for both adjusting its speed as well as its direction.

What’s more, the unit won’t take you by storm on startup. Rather, to give you an indication of its usefulness, this item starts at low-speed and gradually finds its rhythm. As a result, you won’t encounter problems which arise from haphazard starting operations.

Finally, since the motor will turn on only when you press the pedal, it has no noise or vibration when not running. What’s more, due to intermittent stops, it will draw 70% less electricity than an equally-powered clutch motor.

Pros

  • Minimal noise and vibration
  • Lightweight
  • Has a low-speed startup option
  • Best for heavy duty machines

Cons

  • Some customers complained of difficulty in deciphering the instructions mentioned on the motor’s instruction manual.

JUKI Consew

If you have been in the sewing industry for long, you’d have seen Juki embroidery machines around you. Still, while the manufacturer is more famous for its machines, its sewing machine motors aren’t far behind in usefulness either.

Features

Visit the market, and you might not see many motors equally efficient on both light and heavy duty machines. The Juki Industrial sewing motor, however, belongs to that rare category of motors which work well on both the light and heavy duty machines

Why? A mere glance at its features will answer this question. A major difference between light and heavy duty machines lies in the RPM of their motors. For, while heavy duty motors have a high RPM, the opposite is true for lightweight machines.

Consequently, for a motor which claims to cater both, the Juki Industrial motor has an adjustable speed ranging from 0-4200RPM. Therefore, by allowing you to alter its speed based on the task at hand, this unit has dual usefulness.

Talking about safety, and Juki has provided this motor with a pulley cover which keeps the moving parts in check and therefore doesn’t allow any internal wear and tear in the motor no matter for how long you use it.

Pros

  • Useful for both light and heavy duty machines
  • Has a slow starting speed
  • Adjustable RPM
  • Adjustable Speed

Cons

  • Noisy when operating

Final Verdict

There aren’t many motors out there which serve both the hobbyists and heavy duty customers. However, as we have stated earlier, the Juki Consew does the same with aplomb.

Generic CM12-E

Of all the motors in this review, the Generic motor is the most inexpensive. This reduced price tag has a bearing on where you can use it since this motor is not eligible to be used in industrial sewing machines.

Features

There are many features which make this product suitable for domestic type machine, the most important of which is its weight. For, domestic machines are known for their lightweight, and installing a motor which is heavy would negate the purpose of buying them.

Luckily, then, the 1lb weight of this motor would complement the weight of your machine. Without burderning it with too much weight, this motor will give all the features essential for a smooth running of your machine.

What are those features, I hear you ask?

Well, the first of those features is its brilliant energy savings. On startup, this machine will take in 0.09amp of electricity, a figure which would decrease even further as the machine warms up, hence resulting in increased energy savings.

Second, if you look it closely, you would notice the whole outer surface of this motor is polished. Though not the best in the world, this polish will keep the motor from accumulating rust, hence increasing its shelf life.

Pros

  • Good shelf life
  • Inexpensive
  • Huge energy savings

Cons

  • Not suitable for heavy duty products

Final Verdict

If you are a hobbyist who only sews at the weekends, you don’t need to spend astronomically on a sewing machine motor. Rather, what you need is a small-priced motor like the CM12-E.

Consew Servo Motor – 550 Watts, 110 Volts

The final product in our review is yet another servo motor from Consew with all the bells and whistles which you normally expect from such a high-end motor.

Features

One of the many reasons customers choose servo motors is due to their ability to retain their torques at high speed. This machine, as you might guess, does just that. Unlike other, cheap motors which peak at around 2000RPM, this one does the same at many times faster.

What’s more, in addition to peaking at higher RPMs, this one retains up to 90% of the torque generated, even at high speeds. Finally, it is quite and does not suffer or vibrate from resonance issues.

Yet another advantage the selection of this motor will give you is low energy consumption. For example, provided you have taken your foot off the pedal at high speeds. In such a scenario, the unit won’t continue to draw out current from the source, while also holding its position.

That is, even when the motor is kept idle, it will hold the position where you left it. Consequently, you won’t have to go through the arduous, slow startup process which you encountered while starting the motor.

More importantly, you won’t have to navigate through an intricate software to adjust the speed of the motor. Rather, it has a built-in speed control knob for that purpose. Use that knob, and you’d be able to adjust the speed according to your requirements.

To answer the question as to how this machine will keep you safe, it has a safety switch and a fuse for this purpose. Starting from the former, it operates manually and will require you to turn the motor on as soon as you sense something is wrong with the motor.

However, even if you are completely absorbed in your work – and ignore the warning signs, the fuse will come into play to save you. Located on the lead which connects the motor to its cord, the fuse is easy to see and to replace once it goes out of service.

Pros

  • Good safety features
  • Speed Adjusting is super easy
  • Quiet and smooth operation

Cons

  • Requires constant maintenance for long working life

Final Verdict

To be honest, the requirement of constant maintenance will always be there once you decide to install a servo motor. However, the features on offer here aren’t common. Hence, provided you can put up with its maintenance, the motor won’t disappoint.

Conclusion

Whether you wanted a motor for home or industrial uses, your search ends here. Still, if you believe we have missed a good product – or included a bad one – please feel free to let us know.
