    Abstract: A motor control system includes an inverter and a plurality of current sensors each positioned in-line between the inverter and a phase coil of the motor. Each current sensor measures the current provided to each phase coil of the motor and provides a signal indicative of each phase current to a controller. In some embodiments, the currents sensors are provided as one or more current sense integrated circuits. A protection circuit protects the current sense integrated circuit from ground bounce by coupling a diode and an opposite facing Zener diode in series between the power supply pin and the ground pin of the integrated circuit.

    Abstract: A centrifugal blower for HVACR applications includes a squirrel cage forward-curved blower fan and a scroll housing. The blower fan comprises a plurality of blades that are configured to emit air radially outward and tangentially from between the blades when the blower fan rotates at a first speed. The air so emitted has a deviation angle defined as the difference between the direction of the emitted air and the blade exit angle. The scroll housing has a spline-shaped wall that has an axial cross-section that is configured such that the deviation angle of the air emitted from the blower fan at an axial plane deviates by no more than fifteen percent circumferentially about the blower fan in-between the spline-shaped wall and the blower fan and such that the average tangential velocity of air between the spline-shaped wall and the blower fan deviates by no more than thirty percent.

    Abstract: An electric machine is provided. The electric machine includes a rotor and a stator. The stator includes a plurality of teeth and a plurality of windings. Each of the plurality of windings is positioned around at least one of the plurality of teeth. The electric machine further includes a leakage current shielding system. The leakage current shielding system includes a plurality of leakage current shields. Each of the current shields includes a body portion thereof which is positioned between the plurality of teeth and the plurality of windings. Each of the leakage current shields also includes a connecting portion that extends from the body portion. The leakage current shielding system also includes a plurality of connectors. Each of the plurality of connectors is adapted for receiving the connection portion of the leakage current shield. The leakage current shielding system also includes a connecting ring for securing the plurality of connectors.

    Abstract: A quick-release automatic tensioning motor base for supporting a motor. The motor is operably coupled to a device to be driven via a drive belt. The motor base includes at least two base brackets and at least one guide rail fixedly coupled between the base brackets. A platform assembly, which supports the motor, is slidably coupled to the guide rail for movement there along. A spring assembly is selectively coupled between the base brackets and fixedly coupled to the platform assembly. The spring assembly applies a biasing force to the platform assembly to maintain a belt tension along the drive belt. A quick-release assembly selectively engages the spring assembly and the at least two base brackets to permit movement of the quick-release assembly between a first position to retain the spring assembly and a second position to release the spring assembly to permit movement of the platform assembly.
