Abstract
Controls for the electric motors of juice extractors and other devices. The control keeps the motor at a constant speed under changing loads, and the control may allow the operator to select one of multiple operating speeds. Typically, the control will also include a safety switch which keeps the motor from being energized unless conditions consonant with safe operation of the device powered by the motor have been met.
