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 1):
A motor driving apparatus driving an electric blower including a single-phase permanent magnet synchronous motor, the motor driving apparatus comprising:\n a single-phase inverter applying an alternating-current voltage to the single-phase permanent magnet synchronous motor, the inverter including switching elements; a position detecting unit outputting a position detecting signal that is a signal corresponding to a rotational position of a rotor of the single-phase permanent magnet synchronous motor; a current detecting unit outputting a signal corresponding to a motor current flowing to the single-phase permanent magnet synchronous motor; and an inverter control unit receiving the position detecting signal and the motor current and outputting a driving signal to corresponding one of the switching elements of the single-phase inverter, wherein the single-phase inverter increases or reduces reactive power and effective electric power supplied to the single-phase permanent magnet synchronous motor, and the air blower changes an air volume by the increase or reduce in the reactive power and the effective electric power.
