Answer Posted / gopal
A motor designed for line frequencies doesn't have the
inductance to limit current at 25 Hz. And the coupling to
the rotor is inefficient. Driven to provide reasonable
torque it will heat badly.

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
