APPARATUS AND METHOD FOR CONTROLLING ELECTRIC MOTOR |
摘要 |
A control apparatus for an electric motor has a drive circuit that drives the electric motor in which a plurality of phase coils are star-connected, a neutral point drive circuit connected to a neutral point of the star connection, semiconductor relays that cut off an electric path connecting the neutral point and the neutral point drive circuit, and a microcomputer. Furthermore, the microcomputer cuts off the electric path by the semiconductor relays when it is possible to normally drive the electric motor by the drive circuit. |
