Hi
I am trying to use a BLDC motor as a generator using the regenerative braking function. I have a situation where I need to be able to spin it while the e-lock is on, so I am thinking of using relays to open circuit the field windings while I do this. When I close the relays, I want to be sure that I won't damage anything with excessive voltage.
If I spin the motor with the field windings (U, V, W) open circuit will the voltage between field winding keep increasing? Or will the voltage be dependant on the rpm? And when the motor stops spinning, will that voltage on the field windings drop back to 0?
Thanks!
