Title: Device for estimating rotor magnet temperature in permanent magnet synchronous motor
Inventor: TANAKA KENICHIRO
IPC: H02P21/14
Filed: 2020-03-30
Abstract: To provide a device for estimating rotor magnet temperature in a permanent magnet synchronous motor, which can be adopted to a v/f constant control, and requires no induced voltage detection of an electric motor.SOLUTION: When a permanent magnet synchronous motor 13 is in an optional load state, a v/f pattern of a v/f control unit 11 is set in advance so that a d-axis current id on a rotational coordinate axis becomes id=0, and the permanent magnet synchronous motor 13 is continuously operated in the optional load state. A position estimator 15 estimates rotor position information θre from an output voltage command generated by the v/f control unit 11 and an output current detection value of an inverter 12. A coordinate converter 2 estimates the d-axis current id on the basis of the rotor position information θre. A magnet temperature estimator 16 uses: a temperature change coefficient a obtained beforehand from fluctuation of an induction voltage caused by the magnet temperature change; a magnet temperature b in a room temperature; and the estimated d-axis current id to calculate τ=aid+b, thereby estimating magnet temperature τ of a rotor magnet.SELECTED DRAWING: Figure 1
