It also includes, Hall element inputs, a sequencer for commutation control, fixed off time pulse width modulation (PWM) current control and locked rotor protection.

Inside control audit as the stress of audit is decide by the objective and managing key element, at the same time, should give right selection to the new matter and new situation.

With compensation of signal's time delay from different radiating element by phase shifters, phased-array antenna can control array beam easily.
