Abstract
A motor test board is provided which permits automatic testing of an electrical motor under load, in addition to permitting other conventional motor tests. In the preferred embodiment, the motor load is a simulated fan load imposed by a windbat which is calibrated to an intended actual load for the motor. A strobe disc is attached the windbat and is designed to permit determination of RPM and direction of rotation for the motor under test. The windbat and associated structure is automatically attached to the motor undergoing test, and the attaching mechanism is disassociated from the motor and load during test so that the test results closely parallel applicational use of the motor.
