Automated Timing Motor Test Stand

Overview

The Automated Timing Motor Test Stand was a complete test system for small synchronous timing motors. The unit included a fixture which accommodated the testing of two motors simultaneously.

A motor was placed into the fixture with its power leads inserted into two holes, then the operator moved a clamp-down lever toward the motor. The lever was then actuated automatically via an air cylinder to lock the motor in place and begin the testing process.

The system first performed a high-potential breakdown test on the unit. Next, the unit was powered and both speed and direction were sensed and calculated within one (1) second.

This was particularly challenging as some motors moved only an arc second or so within the available test time. The required precision was achieved via gear sets and optical encoders.

At the same time, an electronic brake applied a mechanical load as part of the test parameters. A large display and keypad provided test results as well as the ability to select test parameters such as minimum/maximum speed, direction, load, and more.
