This Scan Actuator Motor, built by the Jet Propulsion Laboratory of Pasadena, California, is part of the Voyager 2 attitude and control system. It was used to "slew" the sensors (rotate them slowly, so that they stayed focused on a target) as the spacecraft passed by the planet Uranus. This motor is a flight-qualified spare, used in laboratory simulations to resolve in-flight problems encountered by the Voyager spacecraft.
Voyager 2 was an unmanned space probe which, in 1986, passed close to the planet Uranus, when it transmitted images of its surface back to Earth.
