Abstract: An electric motor assembly includes a stator assembly and a rotor assembly positioned adjacent the stator assembly to define an axial gap therebetween. The stator assembly is configured to induce a first axial force on the rotor assembly. The electric motor assembly also includes an impeller directly coupled to the rotor assembly opposite the stator assembly such that the rotor assembly and the impeller are configured to rotate about an axis. A fluid channeled by the impeller induces a second axial force on the impeller. The electric motor assembly further includes a hydrodynamic bearing assembly including a rotating member coupled to the rotor assembly and stationary member at least partially circumscribing the rotating member such that rotation of the rotating member with respect to the stationary member is configured to induce a third axial force on the rotor assembly.

Abstract: A motor control system for operating an electric motor is described. The motor control system includes a power supply module disposed external to the electric motor and configured to convert an alternating current (AC) voltage at a first level to a direct current (DC) voltage at a second level lower than a DC-equivalent voltage of the AC voltage at the first level, and a motor control assembly coupled to the electric motor. The motor control assembly includes an input power connector configured to receive the DC voltage at the second level from the power supply module. The motor control assembly also includes an inverter module coupled to the input power connector. The inverter module is configured to convert the DC voltage at the second level to an AC motor voltage to operate the electric motor.

Abstract: A motor controller for an electric motor is provided. The electric motor is configured to drive a blower to generate an airflow. The motor controller includes a memory and a processor coupled thereto. The memory is configured to store a speed-to-airflow ratio associated with an airflow restriction on the blower. The processor is configured to receive a command for a calibrating airflow and operate the electric motor in a constant airflow mode to generate the calibrating airflow at a calibrating speed. The processor is further configured to write the calibrating speed and the calibrating airflow to the memory as the speed-to-airflow ratio.

Abstract: A draft inducer blower assembly for use with a water heater has a housing, a motor, and a fan. The housing has an exhaust volute surrounding the fan and a base adapted to be mounted atop a water heater. The base has an inlet port adapted to receive exhaust gas from the water heater. The fan is connected to the motor for rotation about a rotation axis. The exhaust volute has a cut-off at a cut-off angle relative to the rotation axis. The exhaust volute has an exhaust outlet passageway that extends to an exhaust port. The exhaust port is lower than the top of the exhaust volute.

Abstract: A motor controller for an electric motor includes a drive circuit that regulates power supplied to a stator of the electric motor to turn a rotor. The motor controller includes a communication interface that receives coefficients. The motor controller includes a processor coupled to the drive circuit. The processor receives an airflow rate demand, computes a speed, computes a torque set point as a function of at least a sum of first and second terms. The first term is defined as the first coefficient multiplied by the airflow rate demand raised to a power greater than one, and the second term is defined as the second coefficient multiplied by the speed raised to a power greater than one. The processor controls the drive circuit based on the torque set point to supply electrical power to the electric motor.

Abstract: A motor controller and methods for operating a motor are described herein. The motor controller includes a high-frequency (HF) inverter having a direct current (DC) input stage and an alternating current (AC) output stage, the HF inverter operable at a switching frequency to generate a three-phase output having a fundamental frequency. The motor controller also includes a differential mode (DM) filter coupled in series with the output stage of the HF inverter and having a resonant frequency less than 10% of the switching frequency, the DM filter configured to reduce harmonic components of the three-phase output and generate a first filtered output. The motor controller further includes a common mode (CM) filter coupled in series with the DM filter, the CM filter configured to filter the first filtered output to generate a second filtered output having a reduced CM voltage to operate the electric motor with a reduced bearing current.
