摘要： A motorized pump assembly includes a pump and a motor for driving the pump. The pump includes a pump housing that at least in part defines a pump chamber. The motor includes a stator, a rotor rotatable about an axis, a motor housing, and a bearing assembly. The rotor includes a motor shaft extending along the axis. The motor housing includes an endshield that at least in part defines a motor chamber in which the stator and the rotor are at least substantially received. The bearing assembly rotatably supports the motor shaft on the endshield. The pump housing and the endshield are fixed to one another and cooperatively at least in part define an overflow chamber adjacent the pump chamber. The endshield defines a drainage channel fluidly interconnected with the overflow chamber and configured to direct fluid from the overflow chamber away from the bearing assembly.

摘要： A blower motor is provided for use in a machine. The motor includes a stator and a rotor rotatable about an axis. The stator includes a generally toroidal core, a first-main winding, and an auxiliary winding that is electrically out of phase with the first-main winding. The first-main winding and the auxiliary winding are both full pitch windings.

摘要： A location and retention component is provided for positively locating an overspeed guard and retaining a centrifugal actuator at an optimum positional relationship relative to each other. The system includes a first and second retention element removably engagable to the output shaft of a motor and axially fixable to the shaft at corresponding locations to maintain the optimum positional relationship. The first retention element serves as a positive stop for assembling the overspeed guard on the motor shaft, while the second retention element ensures that the centrifugal actuator is properly placed within the overspeed guard.

摘要： An HVAC system includes a heating/cooling element; an electric motor; a speed sensor; and a control device. The heating/cooling element includes a heating element, a cooling element, and heat exchangers. The motor has a rotatable shaft coupled with a blower wheel. The speed sensor senses a rotational speed of the motor shaft and the blower wheel and includes a magnet coupled with the motor shaft for rotation therewith; and a coil assembly mounted concentrically over the magnet and operable to generate an alternating signal when the magnet rotates relative to the coil. The alternating signal has an electrical characteristic that is generally proportional to the rotational speed of the shaft. The control device determines a rotational speed of the motor shaft and disables operation of the heating/cooling element when the alternating signal indicates that the rotational speed of the shaft drops below a minimum threshold speed.

摘要： A rotor for an electric motor includes a core, a plurality of magnets, and a magnet retention cap. The core is rotatable about an axis and defines a plurality of magnet-receiving slots. Each of the magnets is received in a respective one of the magnet-receiving slots. The magnet retention cap is fixed relative to the core and includes a resiliently deformable magnet retention element configured to restrict axial movement of the magnets relative to the core.
