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.

Abstract: An assembly having an externally threaded pipe nipple with an inserted grommet couples to a motor frame and to a conduit box, supporting the conduit box to the motor frame and providing a pathway for the motor lead through the grommet and nipple into the conduit box. T conduit box configured to house motor lead connections to the incoming power supply. A sealing material, such as a fluid elastomeric material, is poured into the pipe nipple and allowed to cure. The grommet abuts against a stop portion of the pipe nipple, retaining the sealing material. A nut having external threads mates with internal threads of the pipe nipple. As the nut is rotated and tightened, it compresses the sealing material against the inner surface of the pipe nipple and against the motor lead wires, and thus sealing the electrical connections within the conduit box, from the motor and environment.

Abstract: An explosion-proof type rotating electrical machine having excellent cooling and brush powder discharge capabilities. A drive shaft of a rotor is provided with slip rings for supplying current to a field coil, which is energized through brushes capable of activating the field coil by contacting with the slip rings. The brush compartment incorporated with the brushes and slip rings and the outside of the rotating electrical machine are connected with each other through an air suction path, the brush compartment and an inside space of the rotating electrical machine are connected with each other through an air blowing path, in which a flame stifling wire net is provided. When operating the rotating electrical machine in a flammable gas atmosphere, sparks generated due to a contact failure between the brushes and the slip rings ignite the flammable gas filled in the brush compartment to produce flames, the flames then reach the flame stifling wire net by a blowing cool air sucked from the air suction port, where the flames are cooled and extinguished by the flame stifling wire net. Brush powders are discharged to the outside of the brush compartment from the air blowing path by the cooling air.

Abstract: An electromotor, in particular a drive motor for a barrel or container pump, having an outwardly encapsuled motor housing made of a material having good heat conducting characteristics, such as aluminium. The motor housing is provided on its outer side with a shield of an electrically non-conducting material. The shield is surrounded on its outer side with a mantle which forms, with the housing middle portion, a through-stream gap for the passage of cooling air. This outer mantle includes a pair of housing caps, which overlap the end-support shields of the motor housing, and between which housing caps there extends the mantle which shields the outer surface of the housing middle portion by forming the through-stream gap for the passage of cooling air. The outer shielding of the entire motor housing prevents contact with metallic parts and thereby current conducting parts of the motor by a person servicing the device.
