Zusammenfassung:	A motor includes a brake diagnostics system with sensors to assess the brake assembly condition. Acoustic or other vibration sensors provide vibration data that is compared to known vibration spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The brake diagnostics system monitors current flow in the brake coil to assess the condition of the brake assembly. The sensed brake coil current is compared to known coil current spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The voltage input to the brake coil is varied depending upon the current sensed in the brake coil to minimize heat in the brake coil. The motor also includes a resilient layer of thermally conductive material located between the brake assembly and the housing that provides a continuous, uninterrupted thermal pathway between the brake assembly and the motor housing.
