Victor braking feature

[MattB703]

Has anybody out there experimented with the brake feature on the victors. It does not seem to be documented very well. Here are some of the questions I have been trying to answer.

1. I think that the back torque on a motor that is connected to a victor set on brake is linearly proportional to the speed that it is backdriven at. Is this true in theory? Is it true in practice?

2. If a motor is hooked to a Victor that is set on brake and the motor is spun at its free speed, will it develop a back torque that is theoretically the same as the stall torque?

3. What happens if you spin it faster than its free speed?

4. If you keep spinning the motor faster what will be the failure mode? Melting the victor? "Grenading" the motor?

Thanks
