Torque mode DC brush servo amp


Thread Starter

D. Holland

I am looking for a servo amplifier with the following requirements/specifications:

Runs from single 24VDC supply
Torque mode
+/- 10V input
Linear (non-PWM) output for brush DC motors
4 quadrant operation
variable gain
current rating about 2A min
min 5KHz bandwidth

I have found a number of amps which fit most of these requirements, but am having trouble meeting all of them. Any suggestions?
