Manually rotating the motors does generate current and can fry motor controllers. We have fried many Victors and Jaguars this way. We have adopted the following "rule" because of this:

Do not push the robot. Do not manually turn mechanisms. Pick up the robot or use a cart to move it.

Also, we've started adding connectors between the motors and the controllers. Among many other benefits, one is being able to disconnect the motor if we need to manually rotate the motor.
