摘要： An electric machine configured to generate and transfer drive torque to a driveline for propulsion of an electric vehicle includes a gearbox assembly, an electric motor having a rotor and a stator having end windings, and a thermal management system. The thermal management system includes a first end plate disposed at an axial end of the rotor. The first end plate has a central hub and an overhang. The overhang includes an outwardly extending radial rim and a lip. The radial rim includes an outer surface, an inner surface, and at least two passages defined therethrough. The first end plate facilitates cooling of the electric motor by directing fluid (i) off of the outer surface of the radial rim and onto an inner diameter of the end windings, and (ii) through the at least two passages and onto the inner diameter of the end windings.

摘要： A fan motor according to an embodiment includes a bearing holder, a stator, a circuit board, and a synthetic resin. The stator is mounted at an outer circumference of the bearing holder. The circuit board is electrically connected to a coil of the stator, is mounted at a surface of the base part at an opposite side to the bearing holder, and extends from a base part to a connector housing. The synthetic resin seals the bearing holder, the stator, and the circuit board, except for both end faces of the bearing holder. The connector housing has a gate opening that is injected with the synthetic resin at the time of sealing and ribs that are at an opposite side to the gate opening with the circuit board between the ribs, and tops of the ribs making contact with the circuit board.

摘要： A method and apparatus serve to mount a calibrated encoder assembly to an electric motor so that a sensor output signal waveform produced by the calibrated encoder assembly is aligned with a back electromotive force (BEMF) waveform of the electric motor. The calibrated encoder assembly is fixed to an alignment plate, which is attached to the electric motor. The electric motor is rotated using a servo driven functional tester and the BEMF waveform of the electric motor is measured. The sensor output signal waveform is measured, and the alignment plate is adjusted relative to the electric motor to align the sensor output signal waveform to the BEMF waveform. The alignment plate is secured to the electric motor in the adjusted orientation.
