摘要： 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.

摘要： A test board is provided for resistance testing of dynamoelectric machines, and in particular of the windings of an electric motor, in which a standard resistance value is adjusted automatically for changes in ambient temperature. In the preferred embodiment, the standard value is an input to an electrical comparator. A temperature sensor is positioned to sense ambient temperature and the input from that sensor is used to adjust automatically the standard resistance value for the motor under test. The temperature compensated resistance value also is used to determine a range of values about the standard resistant value at the ambient temperature. The resistance of the motor winding then is obtained and compared with the resistance standard. After comparison, an indication is given to the operator of the device, to show a pass or fail condition.
