DanishMan Report post Posted November 28, 2018 Dear Friends I am wondering if any of you could recommend a 220 volt, 0.55KW servo motor for a Pfaff 145. I needs to have needle position and back heel function. Brgds DanishMan Quote Share this post Link to post Share on other sites
arz Report post Posted November 28, 2018 My Jack 561A (750kw) motor has this feature. I may be wrong, but I think the back heel function is pretty common. If I were to buy a new servo motor I would buy a Ho Hsing G60 (or G40 for a smaller motor). It is the best motor for the price I am told. You can buy the Jack or Ho Hsing motors from https://www.college-sewing.co.uk You need to call them for a price on the Ho Hsing motor. Quote Share this post Link to post Share on other sites

Not common with hobby sewing but it's a fantastic feature once you get used to it. Typically with motors it's: Motor only Motor + needle positioning Motor + needle positioning + foot lift output Motor + needle positioning + foot lift output + every thing else (trimmer, backtack, etc etc) College has the Jack, ISM, Ho Hsing and Efka options. The 750w Jack and ISM will offer needle positioning and decent power. The Ho Hsing and Efka will have really good speed control and power but you are also paying for many features you won't use unless your machine is equipped for it. (automatic function solenoids, etc) Quote Share this post Link to post Share on other sites

(automatic function solenoids, etc) I like the power I have with the Jack 750w. The slow speed control is good and the needle positioning seems to work fine. But...I wish it was "just" a little bit slower for detail work. Which is why the Ho Hsing is nice. I have heard that it is not that much more money at College Sewing. Locally it is about 50+ euro ($60+) more than the Jack. Edited November 28, 2018 by arz Quote Share this post Link to post Share on other sites

Locally it is about 50+ euro ($60+) more than the Jack. The Ho Hsing G60 can go as low as 100 spm (according to the manual) and the Jack is about 200? So yeah it would be slightly better, and the price difference is less than the cost of a speed reducer. I am not one to ask though, as I have a curiosity problem when it comes to motors. If I even remotely think one will work better than what I have, I'll try it. My current favorite is the Seiko HVP-70 I picked up cheap on ebay. It's actually made by Ho Hsing. It does everything and the parameter settings chart is endless. 50 spm low speed start, and it's quiet. Quote Share this post Link to post Share on other sites
DanishMan Report post Posted November 28, 2018 I talked with College-Sewing, and they recommended the Jack 563A1 - I guess it is a 561 with a synchroniser. I will try that out. Thanks for your advices. Brgds DanishMan Quote Share this post Link to post Share on other sites

You have to learn how to control it (to get to 200rpm). I put a foam ball under my pedal which helped a lot (old trick that works well!). Good motor though. I believe you can set the Ho Hsing to stop at 100rpm, real nice. That Seiko sounds nice! Quote Share this post Link to post Share on other sites
