Abstract:
A motor driving apparatus according to the present invention is a motor driving apparatus that drives an electric blower including a single-phase PM motor. The motor driving apparatus includes: a single-phase inverter that applies an alternating-current voltage to the single-phase PM motor; a rotor position detecting unit  7  that outputs, to an inverter control unit, a position detecting signal which is a signal corresponding to a rotational position of a rotor of the single-phase PM motor; a motor current detecting unit that outputs, to the inverter control unit, a signal corresponding to a motor current flowing to the single-phase PM motor; and the inverter control unit that outputs a driving signal to corresponding one of switching elements of the single-phase inverter on the basis of the position detecting signal and the motor current. The single-phase inverter performs control to increase or decrease effective electric power supplied to the single-phase PM motor, and the air blower changes an air volume by the increase or decrease in the effective electric power.

Claim (Index 6):
The motor driving apparatus according to  claim 1 , wherein\n the inverter control unit includes a current correcting unit that corrects the effective electric power component of the motor current and the reactive power component of the motor current, and the current correcting unit corrects at least one of the effective electric power component and the reactive power component in accordance with the motor current and the rotating position of the rotor of the single-phase permanent magnet synchronous motor.
