发明名称 MOTOR CONTROL DEVICE FOR DETECTING ABNORMALITY IN POWER TRANSMISSION UNIT BETWEEN MAIN SHAFT AND MOTOR
摘要 PROBLEM TO BE SOLVED: To provide a motor control device which determines abnormality in a power transmission unit without adding a speed sensor or a torque meter.SOLUTION: A motor control device (10) includes: a one rotation signal detector (30) that detects one rotation signal indicating one rotation of a main shaft (23); a rotation angle detector (21) that detects rotation angles of the motor (20) every predetermined time interval; and a counter (11) that integrates the rotation angles. When the one rotation signal detector detects the one rotation signal of the main shaft, a value in the counter is reset. Further the motor control device (10) includes a determining unit (12) that when the values of the rotation angles of the motor integrated by the counter deviate from a predetermined range, determines that abnormality has occurred in the power transmission unit (27).
