Re: Speed Controller Design

Ether,
I have realized we were talking about two different concepts. My mistake. I was talking about locked rotor motor control by driving the motor anti-phase signals to hold the output shaft in place. In this method, current is high through the motor.
I am guessing you are talking about the HBridge control. Your statements are correct. It appears that the Jags can produce this kind of control through the CAN interface only. The current Victor controllers cannot. Both controllers produce zero volts across the motor at zero throttle.
