ABSTRACT:
Systems and apparatus for integrating an air switch and a power cord into an electric motor, and methods for assembling an electric motor including an integral air switch and an integral power cord, are described. In one embodiment, an air switch and a power cord are incorporated into an electric motor. No additional removable cover is required for the switch and cord. To eliminate the motor centrifugal switch, an air switch is provided to control energization and de-energization of the motor windings. The air switch includes a snap action switch to cut-out the start winding used for ensuring that the rotor has sufficient starting torque.
