Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/238381
Kind Code:
A1
Abstract:
A motor control device (10) comprises: an acceleration sensor (2) that is disposed on a printed board (50), that detects acceleration corresponding to the attitude of the printed board, and that outputs the detected acceleration as acceleration information; a temperature sensor (3) that is disposed on the printed board, that detects the temperature on the printed board, and that outputs the detected temperature as detection temperature; an inverter circuit (8) that is disposed on the printed board and that drives a motor (20); and a control circuit (1) that is disposed on the printed board, and that controls the inverter circuit by calculating attitude information indicative of the attitude of the printed board on the basis of the acceleration information, by calculating temperature information indicative of the temperature of components disposed on the printed board on the basis of the detection temperature, and by outputting, to the inverter circuit, a power supply command for a motor based on a temperature threshold set for each piece of the attitude information, the attitude information, and the temperature information.
