RE: [CAD_CAM_EDM_DRO] cheap high speed servo control

Pacific Scientific makes servo motors that just scream on plotters I
service. Here are some rated double what you need:
http://www.pacsci.com/products/servo_motors/pmaproduct.html, that should
be a good start.

If you want cheap, how about an encoder on the machine, a stepper/servo
to get things started, and a DC motor to do the high-speed winding.

JJ
