Abstract
A governor and motor assembly of a fractional horsepower electric motor adapted to control the efficient operation of the motor utilizing simple structural components. The governor is responsive to the centrifugal forces of the rotating rotor shaft of the motor and is attached to the end thereof. The governor includes a carrier plate affixed to the shaft and a pivotable lever mounted within a groove in the carrier plate. A first end of the pivotable lever is connected to the carrier plate by an extension spring which acts to move the lever to its at rest or actuated position. As a predetermined rotational velocity is reached, the lever pivots at the groove to pivot away from the electrical switch aligned axially with the rotor shaft. The electrical switch, in turn, is mounted to a terminal board fixedly mounted to the motor housing to thereby positionally maintain the governor on the motor shaft as well as retain the associated capacitor. In this manner, a minimum of mounting hardware is needed to assemble the governor and control components. The motor housing is provided with indirect venting to prevent fluid splash from damaging the internal components of the motor.
