摘要：
A method of diagnosing DC fan motor performance is provided in which normal operation of the motor is periodically and temporarily suspended in order to verify that the motor is operating within an acceptable performance range. When normal fan motor operation is suspended, the back EMF of the motor is used to determine (i) whether the motor is seized and/or (ii) whether the rate of deceleration after interrupting power to the motor is indicative of a failing motor.
