Abstract
In an apparatus using an inverter as a motor drive apparatus, continuous operation can be permitted during a motor open-phase without providing any additional switching element. Especially, in an electric brake apparatus, higher security can be assured. When a motor winding of one phase occurs an open-phase, currents are conducted to the remaining normal phases while taking the position of a rotor of motor into account to thereby generate torque of the motor. Since the motor torque can be generated continuously in the event of a phase malfunction, reliability of apparatus such as the electric brake apparatus can be improved.
