Abstract
A gear assembly diagnostic system includes an electric motor attached to a gear assembly to be diagnosed, a motor controller coupled to the electric motor to control electric current applied to the electric motor, a test controller coupled to the motor controller to provide commands to the motor controller, and electrical current determining apparatus coupled to provide a measurement of current flow through the electric motor. A programmable data acquisition device is coupled to the electrical current determining apparatus and is programmable to determine current flow through the electrical motor at a predetermined frequency. Data storage is coupled to the data acquisition device for receiving and storing current flow determinations from the data acquisition device and a computer is coupled to, and may include, the data storage. The computer includes software designed to calculate one or more characteristics of the gear assembly to be diagnosed from the current flow determinations.
