How to Install Servo Motor. From Clutch to Servo on an Industrial Sewing Machine

[@BattleAx342]

The Servo motors are very nice for control and speed. I have one on my CB-4500.....

[@rmcdaniel423]

" . . . annnnnd, because I'm lazy . . . " Yes. I understand this sentiment all too well. I too have had to adjust my plan on projects as such.

I inherited a 111w154 head only. I've made the table, mounted the head and cut the slot. Am about to mount the servo so this video came in handy and timely. I alway find your videos helpful and I am subscribed, so keep 'em coming

[@AlexanderDyer]

Thank you for the support. 💥

[@cs3807]

Great video. I have been contemplating doing the same for my Juki DDL-5550.

[@AlexanderDyer]

It will change your machine's behavior for the better.

[@ThoughtFission]

Nice. I haven't seen an analogue speed control for a long time.

I’m a fan of the direct drive version where possible

[@braddobson2060]

Good video. I looked on Amazon and that is one of the more expensive servo motors is there a reason you chose that model. Thanks

[@AlexanderDyer]

Absolutely. I have had several and This is the one I am most satisfied with in this price range. I this video I talk about some of those reasons. kzbin.info/www/bejne/b3vKeHyhbLx1e5Ysi=v4XPQUO9OvMl31Pk

Excellent video friend. I want to buy a servo motor but I have heard that those motors are more delicate than clutch motors, they are damaged quickly when the electrical power is poor.

[@AlexanderDyer]

There are brushless servo motors and those are more finicky and delicate. The one I show has carbon brushes, it is fundamentally different and they have proved out to be very reliable. It is why I recommend these over the brushless. When shopping, if it looks like this, then it will have the brushes and is what you want.

@@AlexanderDyer Thank you very much for your response and your good advice.

I got a pfaff 487 and i' installing a sewmaq motor on it. There was a grounding cable from the sewing machine to the old clutch motor. Where do i screw the grounding cable onto new servo motor ?

[@adolforosado]

Something worth noting. This type of servo motors are brushed and clutched with an electronic speed control. Therefore they are able to provide the punch that a brushless motor cannot, merely because they have to start from zero speed. These have a flywheel already going around ready to transfer the speed in a second. I haven't bought one yet. Do they actually run all the time they're turned on, or they start from zero?

[@AlexanderDyer]

This servo motor does not have a flywheel and clutch. I have never found them deficient in power. Very powerful and very useful. I recommend.

[@adolforosado]

@@AlexanderDyer thanks!!!

[@mosesfennel]

220v vs 110v, which would you recommend?

[@AlexanderDyer]

220v is more efficient but could hurt resale value since not all potential customers would have 220 available. Up to you.

[@mosesfennel]

When I first heard about servo motor. I thought it had a 110v/220v switch just like the clutch motor.

Hi Alexander - I did this to a Juki LU-563 and wonder if certain models are better suited. Now, when I take my foot off the pedal, the servo motor is not providing a strong enough "brake". If I stop while the needle bar is on the way up, the bar has a tendency to fall back down/reverse maybe an 1/8th of a stroke. At this point in the cycle, the hook has just picked up the top thread. The slight reverse motion causes a loop to form which subsequently gets caught on the bottom of the hook assembly. When I start sewing again, the thread snaps. I've mitigated this by adding a needle positioner, but it's not ideal. I'm thinking about putting the clutch motor back on with a smaller drive pulley.

[@AlexanderDyer]

I have used them on dozens of machines. Singer, Juki, Union Special and others. Do you have a speed reducer? Those things are so heavy they get momentum but machines don't seem to by themselves as much. There is a replaceable brake on these if your is worn out. Also you can apply more brake pressure by pushing the pedal with your heal when you wish to stop. This moves the pedal in the opposite direction of go. Does that make sense?

[@scratchypants1]

@@AlexanderDyer - appreciate the reply, thanks. Even without a belt attached, if I cycle the machine by hand and bring it almost to TDC and let go, the needle bar will fall back down. I'm wondering if it might be something bent. As I mentioned, I've all but eliminated the problem with the positioner. Prior to that I was trying to get used to using the heel brake, but that was hit or miss (my fault, not the machine's). Again, thanks for replying - I didn't mean to turn this into a troubleshooting session, but rather to understand if you had experienced a similar issue.
