Ac Brushless As A Generator Can A Brushless DC Motor Be Used As A Generator ?

Can a brushless DC motor be used as a generator ? - ac brushless as a generator

I understand that unless a brush DC motor generates a driver that needs to be run AC power to the device. My question is if I bypass the driver and connecting the motor directly to a bridge, I will flow with reasonable efficiency.

If you use a brush less DC motor 24V to produce energy for about 24?

Thank you for your expertise!
