A system (10) for detecting faults in a motor (12) includes a drive circuit (14), a detection circuit (20), and a controller (22). The drive circuit (14) is configured to apply a drive signal (16) to a motor (12). The detection circuit (20) is configured to detect a response signal (18) generated when the drive signal (16) is applied to the motor (12). The controller (22) is configured to determine a motor fault based on a comparison of the response signal (18) to an expected signal (24) for the drive signal (16) applied to the motor (12). The drive signal (16) is selected to generate a rotating magnetic field in the motor (12) with a rotation-frequency greater than a maximum mechanical-response-frequency of the motor (12). |
