Hi, I'm wanting to change the spindle motor on my little mill to one which I can speed control and which has a bit more speed than the synchronous motor I'm using at present. I have a 24volt 5amp motor which I think will do the job OK but I'm uncertain as to how to control it from EMC2. I will build my own drive electronics - plenty of components, plenty of time, little cash !!;-{. So, what system should I use to control it .... 0-10v, PWM, analogue opto or what.. Can you point me towards relevant literature / examples or maybe suggest a suitable circuit? Thanks
