摘要: A power tool includes a brushless DC motor housed inside housing, an input unit, and control unit. The rotor, stator, at least one sensor positioned to sense state of the rotational position rotor stator. unit controls commutation through series switches coupled supply. receives current from user-selected speed determines whether has reversed direction using state. disables if until proper is received sensor.
