It is more a question of price than anything else , half machined pulleys are available ,but they are not cheap + sending costs + machining the hole and key + transportation costs you can easily end up with a pulley that will costs a third of the complete motor.If you can't do it yourself or know somebody who can ,it is not worth it.

I paid 15€ for one 40mm pulley not cheap but worth every cent. The Jack motors + speed reducer (also custom made) worked great with the original 75mm pulley, I just wanted to have this little bit of extra torque.

Hi Constabulary,

How are you finding the motor? Are you using the standard 75mm or is the 40 mm? How many seconds does it take to go through one stitching cycle on the lowest speed? I wish to go as slow as poss.

I spoke to college sewing and he suggested I buy from somewhere in Germany. Even gave me the name of the people who supply Durkopp. However, he said they would be expensive. I think I will ignore hima nd order from him. :)

Cheers

Alex

I figured I might as well try here in case anyone could actually read this. I'm coming up short within my normal circle of friends and I cant seem to find an english copy of the manual for the motor either and I'm getting an error code when I am trying to configure the NPS, E5 to be specific, but I have no idea what it says. Any help would be greatly apprechiated. 2lxjhcj.jpg

yes yes - me native Chinese - no problem - do translate quick and make code list table...

**Just kidding** :lol:

sorry seems I got you wrong in your PN.

My motor came with a poor English manual but I have a code list. E5 is an synchronizer error - thats why I said my motor does not work with NPS because of the speed reducer. I also had the E5 with the speed reducer installed. Figured I don´t need the NPS at all so I no longer care about it but here is the error code table from my manual

Anyway - still the best servo motor I was able to find on this side of the pond.

Thanks for sharing this. I was eyeing those up the other day and it's nice to read some experiences with them.

I'd love to know more about your speed reducer. The one that came with my 441 clone is a POS and I need a better one.

I have a Ho-Hsing motor on my 441 clone with a needle positioning system and it works with the speed reducer. There is a sensor that attaches to the shaft of the machine on the back of the hand wheel that has adjustments in it. Ho-Hsing were good enough to email me a copy of the manual for the motor, which is pretty ancient, but works fine.

Ho-Hsing are for sure higher end quality motors and are more expensive afaik. But I´m very please with my Jack servo. I don´t really need the NPS but would have been a nice feature though. Still a huge improvement compared with the freaking high speed & energy consuming clutch motors.
