Title: Controller and disconnection detection method
Inventor: MINATO YUICHIRO
IPC: H02P29/024
Filed: 2020-02-13
Abstract: To quickly and surely determine whether or not disconnection has occurred in a sensor for measuring rotation speed of an electric motor by applying no excessive load.SOLUTION: Controllers 53a and 53b include rotation speed sensors 35a and 35b, a power control unit 531, a first coordinate conversion unit 533, a mode transition unit 535a, and a disconnection determination unit 535b. The rotation speed sensor measures rotation speeds of motors 33a and 33b. The power control unit 531 controls an amount of electric power to the electric motors 33a and 33b based on a rotation speed command value ω* and an actually measured rotation speed ω. The first coordinate conversion unit 533 calculates a d-axis current value id. When the rotation speed command value ω* is not 0 and the actually measured rotation speed ω is equal to or lower than a predetermined rotation speed, the mode transition unit 535a shifts to a disconnection determination mode. When the d-axis current value id exceeds a predetermined threshold value after transition to the disconnection determination mode, the disconnection determination unit 535b determines that disconnection has occurred in the rotation speed sensors 35a and 35b.SELECTED DRAWING: Figure 8
