Abstract: An electric motor system is described. The electric motor system includes a drive circuit configured to supply variable frequency current and a contactor configured to supply line frequency current, wherein the drive circuit includes a three-phase inverter and an H-bridge including two phases of the inverter. The electric motor system also includes an electric motor and a controller. The controller is configured to control the inverter to supply variable frequency current to the electric motor over a first duration and determine to control the drive circuit to transition from supplying variable frequency current to supplying line frequency current. The controller is also configured to determine a polarity of a sensed alternating current (AC) voltage, disable at least two switches of the H-bridge, and control the contactor to close, thereby preventing the contactor and the inverter from energizing the electric motor at the same time once the contactor is closed.

Abstract: A blower assembly includes a fan including a front plate that defines a fan inlet. The blower assembly also includes an inlet plate positioned adjacent the fan such that the inlet plate and the front plate define a cavity therebetween that extends circumferentially about the fan inlet. A motor is coupled to the fan and to the inlet plate and configured to rotate about the rotational axis. The motor is positioned within the cavity.

Abstract: Electric motors and drive circuits therefor are described herein. The drive circuit is configured to operate in a first mode of operation and a second mode of operation. The drive circuit includes an inverter configured to regulate current to a first winding and a second winding of the electric motor in the first mode of operation and to only the first winding in the second mode of operation. The drive circuit also includes a first switch coupled to the second winding and configured to supply line frequency current to the second winding at a first node in the second mode of operation, and a second switch coupled to the second winding and configured to enable selection of regulating current to the second winding using the inverter in the first mode of operation or supplying the line frequency current directly to the second winding in the second mode of operation.

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 combustion air blower includes a blower housing, an impeller fan within the blower housing, and an embossment to restrict airflow from the combustion air blower. The blower housing has a discharge conduit defining a discharge passageway. The discharge conduit is adapted and configured to receive a baffle such that, when the baffle is received, the baffle extends inwardly into the discharge passageway from a first wall towards a second wall opposite the first wall. The baffle restricts airflow within the discharge passageway. The embossment is in the discharge passageway and in the second wall and extends towards the first wall such that the embossment restricts airflow within the discharge passageway. The embossment cooperates with a baffle to provide a reduced cross sectional area of the discharge passageway in comparison to an upstream portion.
