  • Publication number: 20200021150
    Abstract: A motor is cooled with a coolant. The motor includes a rotor rotatable about an axis, a stator including a stator core and windings wound about the stator core, a housing enclosing at least a portion of the stator, and a resiliently deflectable spray ring extending circumferentially relative to the axis. The spray ring defines at least one orifice configured to direct coolant on the stator. The spray ring presents first and second arcuately spaced apart ends defining a gap therebetween.

  • Patent number: 9127666
    Abstract: A pump motor assembly operable to provide driving power to a fluid pump includes a rotor, a stator, a case housing the rotor and the stator, and a control assembly mounted to the case and operable to control motor operation. The control assembly includes an information display and a cover overlying the display, with a window section in general alignment with the display. The control assembly also includes a filler plate underlying the window section to prevent any air gap along an underside thereof, allowing the display to be visible while reducing the risk of condensation buildup. The control assembly further includes a low voltage housing with the display disposed in a first compartment defined thereby, and a high voltage housing with a high voltage component disposed in a second compartment defined thereby.

  • Patent number: 8350423
    Abstract: A cooling system is provided for an electric motor having control circuitry and including a motor housing surrounding the motor. The motor drives at least one radial fan at one end thereof for directing airflow through the motor housing across the motor. A fan housing encloses the cooling fan and defines a diverter chamber radially outboard of the fan that is sized to divert a portion of the airflow away from the electric motor. A control box contains the control circuitry and includes a base having a heat sink for contacting the control circuitry. The base defines a plenum in communication with the diverter chamber and a channel in communication with the plenum and the heat sink to direct the diverted airflow across the heat sink.

  • Patent number: 8283824
    Abstract: A fluid deflecting baffle is provided for use on an electric motor to be used in an environment where liquid may otherwise pass through a vent opening in an endshield of the motor. The baffle is secureable to the endshield and extends in a partial covering relationship with the vent opening. The baffle includes a vent passage therethrough and has at least one liquid flow obstructing louver that extends across the vent opening to deflect liquid away from the vent passage while allowing venting air to flow through the vent passage. The louver includes a generally flat liquid deflection surface that is disposed at an oblique angle relative to the axis of the motor and at least partially faces a venting direction of incoming air and fluid.

  • Patent number: 6487769
    Abstract: Methods and apparatus are disclosed for assembling an electric machine. The electric machine includes a plurality of stator segment assemblies that are mounted inside of a housing of an electric machine. The stator segment assemblies are positioned around an outer surface of an assembly fixture. The stator segment assemblies are held to the assembly fixture using a magnetic field that is generated by the assembly fixture. The housing is press fit or hot dropped over the stator segment assemblies. If the housing is hot dropped, the housing is heated to cause the housing to expand. The housing is positioned over the stator segment assemblies while the housing is hot. The housing cools and contracts around the stator segment assemblies to form an interference fit with the stator segment assemblies and then the stator and the housing are removed from the assembly fixture.

  • Patent number: 5602436
    Abstract: A dynamoelectric machine of the present invention includes a stator, a rotor journaled with respect to the stator, and a rotor shaft having a longitudinal axis extending axially from said rotor. An auxiliary winding and a starting switch operable to de-energize said auxiliary winding upon the motor obtaining a predetermined speed is provided. A centrifugal actuator is mounted on the rotor shaft to actuate the starter switch to de-energize the starter windings when the rotor obtains a predetermined speed. The rotor shaft has a single wide groove formed thereon and the actuator has a sleeve which is journaled on the rotor shaft. The sleeve has an inwardly directed projection sized and shaped to fit in the shaft groove. The sleeve projection and shaft groove interact such that the actuator sleeve cannot be moved relative to the shaft and the switch without a great deal of force.
