Re: Blown talon srx modules

Turning a motor when it is unpowered does generate a voltage. That voltage is no different in principle from the back EMF that the motor generates when it is powered.

Unless you're backdriving the motor much faster than its free speed, I don't think you're going to create a situation where the speed controller is in any danger.
