Hello all,
I have an AC motor with a pretty straight forward torque/rpm curve. However I would like to estimate braking torque that can be applied by the motor. I am not so much concerned with how much power is regenerated but wasn't sure how the motor performance differs when used for braking. I read that regenerative braking is ineffective at low speeds because speed and output voltage for a generator are proportional, but the braking torque is still the same? (i.e. the motor still brakes with the same forces it just cant convert it to energy bc low voltage)
Thanks,
Corey
