Abstract: Embodiments of the disclosure provide an inverter controller operable to perform inverter controller operations that include performing a continuous carrier alignment methodology on an inverter. The continuous carrier alignment methodology includes, for a current sampling period, evaluating a shape of a carrier waveform from a prior sampling period; and determining, based at least in part on an ending location of the carrier waveform from the prior sampling period, whether or not to insert an intermediate carrier shape into the carrier waveform during the current sampling period.

Abstract: A method of forming a tensioner arm bracket, chain guide, snubber or tensioner arm with two shot injection molding. The tensioner arm bracket, chain guide, snubber or tensioner arm each having a body and a chain sliding face. The body of the tensioner arm bracket, chain guide, snubber or tensioner arm bracket is formed of by a first shot of thermoplastic polymer or thermosetting resin and the chain sliding face is formed by a second shot of thermoset elastomer which is overmoulded onto the body. The body of the component is made of either a thermoplastic or thermosetting resin is fixed to its chain sliding face either by one or more of an anchor point generated by undercuts in the body and/or chemical bonds between the dissimilar materials.

Abstract: A motor housing 20 for an axial flux motor 10. The motor housing 20 includes at least one housing portion 22, 24 which is of at least partially double-walled configuration, in order to configure an internal cooling channel 40 in the housing portion 22, 24. The cooling channel 40 extends in a substantially annular manner in the circumferential direction 6 between an inlet 41a and an outlet 41b, in order, during operation, to produce a first cooling flow 82 which flows substantially in the circumferential direction 6 through the cooling channel 40. Furthermore, the cooling channel 40 includes a plurality of transverse ribs 50.

Abstract: An electric motor includes a stator and rotor. The stator includes a stator core defining a stator bore, and a plurality of windings having end turns extending from the stator core. This includes a central region configured to be disposed in the stator bore, and first and second end regions extending from the central region and aligned with the end turns of the plurality of windings. The rotor defines a cooling bore in fluid communication with a low-pressure cooling fluid source and includes a plurality of cooling jets in fluid communication with the cooling bore and disposed in the first and second end regions. The plurality of cooling jets extends radially outward such that each cooling jet is configured to pull cooling fluid through the cooling bore and eject cooling fluid toward the end turns in response to centrifugal force caused by rotation of the rotor within the stator bore.

Abstract: A stator for an electric machine includes a core and a multi-phase winding arrangement positioned on the core. Each phase of the winding arrangement includes a plurality of parallel paths defining a plurality of poles for the electric machine. Each parallel path includes a plurality of coils positioned on the core, each coil defined by coil legs and end turns. The coil legs include left legs and right legs extending through the slots of the core. The left legs and right legs of each coil are connected by first end turns at one end of the core and second end turns at an opposite end of the core. Each pole of the electric machine is associated with a pole slot set comprised of multiple slots on the stator core. For each pole slot set, legs for each parallel path extend through one of the slots of said pole slot set.

Abstract: A rotor assembly includes a shaft defining a lubricant inlet channel for receiving a lubricant and a lamination stack. The lamination stack is rotatably coupled to the shaft, extends between first and second lamination stack ends, and defines a lubricant cooling channel in fluid communication with the lubricant inlet channel. The rotor assembly also includes a first end cap adjacent to the first lamination stack end and a second end cap adjacent to the second lamination stack end. One of the first end cap and the second end cap defines an end cap inlet at a first radial distance from the shaft, a lubricant outlet channel defined to extend at least partially radially inward toward the shaft, and an end cap outlet at a second radial distance from the shaft which is less than the first radial distance for expelling the lubricant.
