Bidirectional brushless DC motor controller
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

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.
