摘要：A motor drive apparatus comprises: a position signal generation portion thatgenerates a position signal corresponding to a rotor position of a brushless DC motor;and a logic portion that when starting the brushless DC motor, disposes a non-energizingperiod immediately after starting forced commutation at a phase switchover timing

corresponding to a predetermined forced commutation frequency and performs

energizing control of the brushless DC motor such that usual commutation is started at aphase switchover timing corresponding to the position signal that is generated during aninertial rotation of the rotor.
