New Brushless Servo Motor For The Mini Lathe
118,801
Published 2022-04-23
It seems that this happens to most of the Mini Lathe users at some point.
As I have no clue about electronics and heard some good reviews of the brushless servo motors, supplied for industrial sewing machines, I decided to replace the old motor and electronic with such a kit.
So far I'm really happy with the performance. At the moment the controller and main motor switch are just installed provisorily. But there are plannings for integrating both in a much smoother way. Especially the motor switch is a bit strange to use as it is intended for a foot pedal use. But we will see, if we can implement it in a useful way in the future.
I hope you enjoy this episode. If there are questions or suggestions, let me know in the comments.

I like it. Simple yet effective and efficient solution to your motor blowing up. I replaced the motor on my Unimat DB200 with a brushless but instead used a potentiometer. Works great.

Nice !! I was waiting for this video. Awesome idea and installation. Great job!! Cheers from Canada.

Just found Your channel. No idle talking, straight to the point, nice angles and good work overall. Subbed :)
-
I deal with sewing machine repairs and was going to do this exact same thing as my mini lathe packed up 😄 thank you for the video. Now I've got more confidence to set it up

"A short glimpse and the situation is clear: I have absolutely no clue about electronics!" I like the cut of your jib, as i do the same thing, but i am learning.

inspired by your video I order the servo motor. but I faces some difficulties finding the right pulleys and belt, so I decide to remove the rotor and rework the shaft to 8mm. Now I am waiting for the new belt to finish it. thanks for sharing, your skills are really inspirational.

Wow, great work!

Nice! I've thought about using these sewing motors for machine builds for a while. The 500w ~4000rpm would make them ideal for drill press, mini grinder type projects.

0:40 - for those connectors, there is a small "latch" built into the socket side. When you press it, it releases a bent metal pin that fits into a hole on the plug and locks it. You can press the latch after sliding back the plastic over-cover, it's possible with bare finger but easier to do with a small screwdriver or something similar to poke it with..

Quite nice idea for a motor/drive substitution or rather better to say: improvement !?! - perfect 👍🏻. I'll keep that solution in my mind for my mini lathe. Nice Video, as always. Weiter so!

Endlich! Darauf habe ich schon lange gewartet! :)
-
I already liked your videos, but they keep getting better and better. Nice editing and camera setups! Also: this upgrade is very interesting. I'm thinking about buing a minilathe. Just so I can upgrade it ;-)
-
Glad you're speaking in your newer videos. Great work.
-
I bought a similar lathe one year ago. Its from 1999 and i have almost the same issues with it like you (but my motor still runs). Therefore I am verry interisted in your videos and solutions. Weiter so, Grüße.

Nice motor choice! 👍
-
I have been looking at the same (or very similar) motor for my small lathe on my favourite Chinese e-shop. You have persuaded me to buy it.
-
Very interested to see how this goes. I bought one of those motors for my Taig Lathe. Probably overkill for that tiny machine, but it was cheap.
-
These motors are brilliant….so many uses
-
A 10 turn potentiometer, Bourne makes some nice ones, with the same resistance sweep as the sewing machine speed controller would provide a very accurate fine adjustment. You can install a mechanical indicator on the shaft of the potentiometer to indicate which turn you're on and or install a tachometer.

Looks like i am going to have to do this . My machine went bang yesterday !
