    Abstract: A housing assembly for an electric motor having a rotor shaft rotatable about an axis includes a housing cover and a housing case. The housing cover defines a first bearing seat for rotatably supporting a first portion of the rotor shaft. The housing case defines a second bearing seat for rotatably supporting a second portion of the rotor shaft. At least one of the housing cover and the housing case includes a plurality of mounting lugs substantially circumferentially evenly spaced about the shaft axis for mounting the electric motor to a surface.

    Abstract: A motor includes a shaft that extends along a rotational axis and an end frame that includes a first surface that is substantially normal to the axis. A first plurality of annular features are arranged concentrically about the rotational axis and coupled to the first surface. A fan is mounted to the rotating shaft and including a slinger portion and a second surface. A second plurality of annular features are arranged concentrically about the rotational axis and coupled to the second surface. The first plurality of annular features cooperate with the second plurality of annular features to form a non-contact seal between the fan and the end frame.

    Abstract: An electric motor is provided. The electric motor includes a motor controller configured to convert AC power to a variable frequency variable voltage power for driving the electric motor according to a commanded motor output. The motor controller includes a PFC circuit configured to control a power factor of the electric motor and a microcontroller coupled to the PFC circuit and configured to activate the PFC circuit when the commanded motor output is greater than a threshold motor output, deactivate the PFC circuit when the commanded motor output is less than or equal to the threshold motor output, and generate a control signal based on the commanded motor output. The motor controller further includes an inverter configured to receive the control signal and generate the variable frequency variable voltage power according to the commanded motor output.

    Abstract: A control system for a cooling system configured to selectively operate one or both of a condenser fan an evaporator fan in a reverse direction RD, measure power draw at the motor against configuration data and fan motor profiles, and determine if a blockage has occurred before the static pressure has reached a critical point static pressure where the efficiency, performance, and cooling capability of the cooling system is hindered and maintenance is required to clear the blockage. By determining if blockage has occurred before the static pressure has reached the critical point static pressure, an alert or corrective action can be taken.

    Abstract: An electric motor for a pump includes an AC line-in node for receiving AC power supplied to the electric motor. The electric motor includes a current sensor coupled to the AC line-in node and measures current supplied to the electric motor. The electric motor includes a motor controller configured to convert the AC power supplied to a variable frequency variable voltage power for driving the electric motor at a normal output value. The motor controller includes a microcontroller and an inverter. The microcontroller is coupled to the current sensor and receives a measured value of the current supplied to the electric motor, determines the measured value is above a threshold, and transmits a control signal representing a reduced output value. The inverter receives the control signal and generates the variable frequency variable voltage power to reduce output from the electric motor according to the reduced output value.
