Sure enough! I had been looking at a mix of 110 and 220v motor/drives. Now that you pointed that out, it looks like none of the 400W under-$100 motors are 110. There are 550W (3/4HP) motors for $120, and 750W (1HP) for $150. Hmmm. -- Ralph From: John Ba

I have some industrial sewing machines. Some of the cheap brushless motors have a reputation for poor low speed torque. However some of the higher end brushless motors are apparently ok. Check out the motors available from Sailrite.com. If you do some digging you will realize that Consew (a

Dear Friends, Been away from the EMC arena for a while, but my machines are running as usual. Now I have to take care of that Körner engraver I was talking about more than a year ago. I've decided that the easiest way to make this happen is to rip out the old controller and make new stuff. So, my

Thank you guys for the replies. The simplest mechanism that I've seen so far is the one used in the nail making machines but they don't use a stop for setting the lenght. I'll try to design both alternatives and see wich one suits me the better. 2018-07-02 22:12 GMT-03:00 Dave Cole : > Oftentime
