guildsmyn Report post Posted September 6, 2018 hey folks, I have looked at most of the treads on servo motors, most thread are a few years old. Just wondering what people are currently recommending for servo motors. I am looking for good torque at lower speeds for thicker leather. I will be sewing layers 1/2 thick, but will also need to sew thinner leather. Any thoughts or recommendations would be appreciated. thanks Quote Share this post Link to post Share on other sites

Albob Report post Posted September 6, 2018 I put a servo on my 111W155 and it works great for thinner stuff. I also just got the Cowboy 3200 which came with a servo and speed reduction set up for high torque at low speeds for the heavier stuff up to 1/2". Both the servo conversion for the Singer and the ready to sew Cowboy came from Bob at Toledo Sewing. You can't beat his customer service, give him a call.

Konapaniolo Report post Posted September 6, 2018 Not sure if your gonna get enough lift on the feet of your 145 to accommodate 1/2" thick leather. Amazon has the motors also... Quote Share this post Link to post Share on other sites
dikman Report post Posted September 6, 2018 (edited) Good torque, low speed and leather - you will need to factor in a speed reducer with the motor, as already mentioned. A servo, by itself, will not meet your requirements. Other than that, if you're uncertain about a motor stick to the brands the advertisers here sell.

Uwe Report post Posted September 7, 2018 There are a few modern servo motors out there that have very high power and torque and a very slow starting speed of 100 RPM (most servos start around 300 RPM). But these motors are hard to find. One US based vendor is SewPro, who sells the SP-1100, check this topic for details: I was looking for an alternative to the SewPro motors and eventually ordered some 1,000 W servo motors directly from a manufacturer on Alibaba earlier this year for testing. Turns out the motors are very nice and they even installed small 50mm pulleys for me at the factory. My main requirements were: 1KW power, separate motor, controller, and speed input components for flexible mounting, 100 RPM starting speed, 50mm pulley, needle position sensor option, intuitive keypad with quick and direct speed control buttons and a dedicated needle position button with Up/Down/Off modes. It took me months to find this one. I'm NOT planning to re-sell these motors, which is why I'm sharing the sourcing info here. Downside of sorts is you have to buy them in multiples of four motors. Shipping via air express was quick but pricey and a bit sketchy - DHL is just as bad as the other guys. Luckily all four motors survived the rough handling. Next time I'll order enough motors to ship them on a pallet via ocean freight. I have plenty of machines that need motors. Alibaba is really a Businees-to-Business marketplace and not geared towards end users. It's definitely not like Amazon. Alibaba works best if you have a sense of adventure, enjoy the occasional gamble, and have patience communicating with folks who's English may be spotty but is still way better than your Chinese.

dikman Report post Posted September 7, 2018 Intuitive keypad? That would be a first. I notice that the specs list the slowest speed as 500rpm? Lishui is the company that made the servos I bought (three of) and so far I've had no issues with them. It should be possible to find the same motor on Aliexpress, which deals with individual sales, but it could take a lot of searching and the price will probably be higher.

In other news, just realized that the SP-1100 motor is also available from @Gregg From Keystone Sewing with quick and easy online ordering. I'm glad to see that type of motor offered by additional vendors. Quote Share this post Link to post Share on other sites
