摘要： If magnitude relations between the output terminal voltage based on a DC negative terminal of the inverter and a threshold voltage that is a fixed value are compared, polarity thereof is changed at a predetermined rotor phase. The magnitude relation, for example, is detected by an inexpensive and simple apparatus such as a level shift circuit and a NOT circuit. The rotor phase of the permanent magnet synchronous motor is inferred on the basis of changes in the magnitude relation and if it is differentiated, a rotation speed is inferred. If the inferred values of the rotor phase and rotation speed are fed back to synchronous operation or vector control, the free-running permanent magnet synchronous motor is restarted.

摘要： A motor control system includes a power converter, a vector controller for controlling the power converter, an axial error estimating operation for estimating an axial error which is a deviation between the phase estimation value and phase value of the motor, and a rotational speed estimating computing unit 5 for performing control so as to equalize the estimation value to a command of the axial error, a motor constant identification computing unit. The motor constant identification computing unit identifies a motor constant with a q-axis voltage component and a rotational speed identified value or a rotational speed command to reflect the identified motor constant in the vector controller.
