[Emc-users] Mixing BLDC and brushed motors

2014-09-04 Thread John Prentice (FS)
Greetings This is probably a question for PCW but others might know or have dome it. I am looking at a small machine design where two axes will be BLDC motors and one (or perhaps two) brushed DC. The BLDC motors suit a 7i39 very well (interfaced by a 5i20). Are there any problems in

Peter thank you -Original Message- From: Peter C. Wallace [mailto:p...@mesanet.com] Yes you can look at the 7i39 as 6 individual 1/2 bridges and drive 3 DC motors from one 7i39. if a brushed motor was connected to half bridges A and B, I _think_ what is needed is to drive A with the PID
