Motor control device

A motor control device configured to control a motor, comprising:

• a computer including a processor and a memory that stores instructions configured to, when executed by the processor, cause the processor to
• determine whether a motor rotation control to rotate the motor fails;
• calculate a control failure frequency parameter having a correlation with a frequency of failure in the motor rotation control based on a result of the determining;
• calculate a control failure probability that is a probability of failure in the motor rotation control by dividing a number of control failures by a number of starts determine whether an abnormality has occurred in the motor based on the control failure probability;
• and
• suppress stop of rotation of the motor by changing a motor control parameter to perform the motor rotation control when it is determined that the abnormality has occurred in the motor.
