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.

Claims

1. A motor and control system comprising:

a motor housing enclosing a rotor and stator including one or more windings;

a drive controller disposed within the motor housing, wherein the drive controller includes;

a motor control circuit including at least one system operating profile, and

a remote communication interface configured to wirelessly communicate with one or more servers using a communication network,

wherein,

the motor control circuit is configured to wirelessly access a selected system operating profile from a plurality of system operating profiles located at the one or more servers via the remote communication interface, wirelessly receive an operating parameter based on the selected system operating profile located at the one or more servers, update the system operating profile of the motor control circuit based on the wirelessly received operating parameter, compare an indication of operation received from a sensor to the wirelessly received operating parameter, and increase or decrease a rate at which the motor operates based on a comparison between the indication of operation received from the sensor and the wirelessly received operating parameter.
