Abstract
Mechanisms are provided to control the operation of a motor. In particular, a variable frequency drive motor controller is described which resides within a motor housing. Additionally, the speed at which the motor operates is based on a signal received from a Hall Effect switch or from a communication device in communication with a remote interface. The Hall Effect switch is also described; in particular, the Hall Effect switch features a magnet rotatably connected with one side of a motor housing. A Hall Effect sensor, located on the opposite side of the motor housing, detects the position of the magnet and outputs a signal to the motor controller, located within the motor housing, indicating the detected magnet position. Additional operating features are described relating to the safe operation and control of the motor in potentially hazardous environments.
