| titleOfInvention | Electric motor control device |
| abstract | In an apparatus for driving and controlling an electric motor without using a position sensor, the magnetic pole phase of the rotor is accurately estimated and the electric motor can be stably estimated even when the rotor is rotating at a high speed from a stopped state. An electric motor control device capable of driving the motor is obtained. A phase estimator 6 that estimates a magnetic pole phase in a relatively low speed region and outputs an estimated phase θs, a magnetic flux estimator 8 that estimates a magnetic pole phase in a relatively high speed region and outputs an estimated phase θ0, and a predetermined The phase switching unit 9 that directly outputs the estimated phase θs to the estimated phase θ0 or the estimated phase θ0 to the estimated phase θs at the set speed is output as the phase signal θm.
