Abstract: A bearing assembly may include an integral sensor module retained within a bore in the bearing housing. The sensor module includes at least one strain gauge oriented to sense a compressive load acting on the bearing housing. The sensor module may be retained within the bore under an axial compressive load. The sensor module may include a power source and a wired or wireless communications module for transmitting information indicative of the compressive load to an external instrument or other system.

Abstract: A stator assembly for use in an axial flux electric motor includes a plurality of tooth assemblies and a plurality of circumferentially-spaced stator bases that are each coupled to at least one tooth assembly. The stator assembly also includes a plurality of circumferentially-spaced bridge members. Each bridge member is configured to engage a pair of circumferentially adjacent stator bases to apply an axial pre-load force to the pair of stator bases and to create a flux path between the adjacent stator bases.

Abstract: A drive circuit for a permanent split capacitor (PSC) motor includes an inverter, a solid state switch, and a contactor coupled in parallel with the solid state switch. The inverter is configured to supply variable frequency current to the PSC motor over a first duration. The solid state switch is configured to supply line frequency current to the PSC motor at the expiration of the first duration. The contactor is configured to supply the line frequency current to the PSC motor over a second duration beginning when the contactor closes after expiration of the first duration.

Abstract: A fan drive circuit for a variable speed fan motor in a cooling system, includes an inverter configured to supply a current signal to stator windings of the variable speed fan motor, a frequency detection circuit coupled to an output stage of an inverter of a compressor motor of the cooling system and configured to detect a first frequency of a compressor current signal at the output stage of a variable speed compressor drive circuit and generate a frequency signal, and a digital signal processor (DSP) coupled to the inverter and the frequency detection circuit. The DSP is configured to receive the frequency signal corresponding to the first frequency from the frequency detection circuit, select a second frequency corresponding to the first frequency at which to operate the variable speed fan motor, and transmit control signals to the inverter to supply current to the stator windings at the second frequency.

Abstract: A blower assembly includes a fan assembly configured to rotate about an axis and having a fan inlet ring that at least partially defines a fan inlet and a fan outlet. The blower assembly also includes a frame assembly coupled to the fan assembly and a recirculation damper coupled to the frame assembly. The recirculation damper and the fan inlet ring define an axial gap therebetween to reduce recirculation of an airflow discharged from the fan outlet.

Abstract: A motor controller for an electric motor is provided, including a drive circuit and a processor. The drive circuit regulates power supplied to a stator of the electric motor to turn a rotor and blower to generate an airflow. The processor receives an air density, an airflow rate demand, and at least one of a measured torque and a measured speed of the electric motor. The processor computes one of a torque set point and a speed set point for the electric motor using an airflow algorithm and based on the air density, the airflow rate demand, and the at least one of the measured torque and the measured speed. The processor controls the drive circuit based on the one of the torque set point and the speed set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: A motor controller for an electric motor for driving a blower to generate an airflow. The motor controller includes a processor and a drive circuit configured to regulate power supplied to the motor to turn the blower. The processor computes a system resistance for the blower based on a fixed set point for a first control parameter and a feedback parameter. The processor receives an airflow rate demand value and computes an operating set point for a second control parameter based on the system resistance and the airflow rate demand value. The processor controls the drive circuit based on the operating set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: Methods and systems for controlling an electric motor using a motor controller including a processor are provided. The method includes transmitting, by the processor, a no-spin signal commanding the electric motor not to spin, receiving temperature information associated with a temperature of the electric motor, comparing the temperature information to a predetermined threshold temperature to determine whether the temperature is at a sufficient level to prevent icing, and adjusting current applied to the electric motor when the temperature measurement is below the predetermined threshold.
