Preventing Induction While Towing
Preventing Induction While Towing
(OP)
We have a permanent magnet AC motor on a vehicle. When the vehicle is being towed, the motor might induct current. Is there is a way to prevent this from happening without disengaging the mechanical connection between the wheels and the motor? Thanks.

IRstuff: that would be perfect, but we cannot do that on that vehicle. Regards.

The gears do turn however. I'd like to find a drive motor or planetary gear that allow for some sort of free wheeling that doesn't turn the inner workings. The possibility of using an electric drive is there too, if I can find one that meets my needs.
Anyone using an electric drive or hydraulic drive motor or planetary gear that allow free wheeling without turning internal mechanisms?

The Buick had a similar component which was toothed. A dog engaged the teeth to provide the parking brake function.

You should consider an electric drive for your machine that turns off, (opens a contactor), to the motor when the throttle pedal it lifted. Then the motor is essentially disconnected and you can tow it with no mechanical load except for the fan in the motor. Would be a bunch easier then some mechanical disconnect. Furthermore I can guarantee that you will have a lot of cases of your machine being towed without being mechanically disconnected by some lamoid. I see that occur in all industries, most of which aren't as hectic as aviation. I have seen rail cars dragged miles without their brakes released, cars towed in gear, etc , etc.
