Indirect analysis of motor condition through vibration and current analysis

This paper explains an offline testing procedure to determine the condition of a used DC motor in order to determine whether it needs to be serviced or is viable for continued operation. Through the use of common test equipment, several motor measurements such as vibration, acoustic amplitude, and current variance can be analyzed to determine the condition of the motor. This procedure is vital in quality measures and preventative maintenance in order to reduce downtime. This testing procedure was tested on the Tennant version of the Briggs and Stratton Etek DC motor
