Abstract

Abstract An automatic electric motor testing facility provides a plurality of carriers for carrying motors to a plurality of testing stations at which tests are performed. A memory arm having two levels of memory and an attached reflector assembly is connected to each carrier for selectively actuating each testing sequence through photoelectric transducers located at each testing station. Memory arm control means located at each test station selectively control the memory level of each memory arm in response to the test results. A tabulating punch provides a test record at each carrier while tabulating counters at the test control further record test results. The test control also provides a resistor bank having a plurality of resistive elements which are selectively code connected to one another, to a power source, and to an output circuit by a data card reader for providing a plurality of presettable electrical outputs for automatically controlling the testing of the electric motors.
