ABSTRACT:
An abnormality detecting system, for detecting an abnormality in a rotor position detector for detecting a magnetic pole position of a motor, includes a speed calculator for calculating the speed of the motor, and an abnormality detector for detecting an abnormality in the rotor position detector. A method for detecting an abnormality in rotor position includes calculating a instantaneous speed and average speed of the motor, judging whether or not the absolute value of a difference between the instantaneous speed and the average speed is greater than a set value, and, when it has been judged that the absolute value of the difference therebetween is greater than the set value, detecting an abnormality in the rotor position detecting means. A motor control system includes the rotor position detector, torque instruction value detector, a PWM signal control device, an inverter, the speed calculator, the abnormality detector, and a PW signal interrupter.
