Where can I find high power bidirectional brushless DC motor controller? I am looking for something like R/C airplanes use but bidirectional. 30V-60V and 70A or so.

Any leads?

thanks
Jim

 

Just a guess, but try these folks: http://www.robotpower.com/

Is your motor with permanent magnet fields? If it's not you will need to change the field connection to reverse.

If permanent magnet perhaps you could use 2 uni-direction controllers, one forward, one reverse with a diode to prevent back feed.

Servo (or bi-directional) single axis motion controller with build-in power amp you may find in Elmo (www.elmomc.com) - see Drum type.
