    摘要： An enclosure for an electric machine includes a housing defining an axial bore having an opening at a first end of the bore. The housing comprises a first wall having a first inboard surface partially defining the bore, and a first outboard surface spaced from the first inboard surface, the first wall defining a first coolant channel disposed between the first inboard and first outboard surface. An end cap is fastenable to the housing to cover the opening.

    摘要： A generator includes a stator core having a set of stator poles formed by a post and a wire wound about the post to form a stator winding, with the stator winding having end turns, a rotor having a set of rotor poles and configured to rotate relative to the stator and a rotor channel for liquid coolant to flow through the rotor to a set of coolant apertures, and a set of rotor pole coolant channels aligned with and proximate to the set of rotor poles. The liquid coolant flow extracts heat from the generator.

    摘要： An aircraft starting and generating system includes a starter/generator and an inverter/converter/controller (200) that is connected to the starter/generator and that generates AC power to drive the starter/generator in a start mode for starting a prime mover of the aircraft, and that converts AC power, obtained from the starter/generator after the prime mover have been started, to DC power in a generate mode of the starter/generator. A four leg inverter is coupled with a DC power output (452) of the starter/generator and has an inverter/converter/controller (ICC) (580) with a four leg MOSFET-based bridge configuration that drives the starter/generator in a start mode for starting a prime mover of the aircraft, and converts DC power to AC power in a generate mode of the starter/generator. A four leg bridge gate driver (560) is configured to drive the four leg MOSFET-based bridge (580) during start and generate mode using bi-polar pulse width modulation (PWM).

    摘要： A wet cavity electric machine includes a stator core having stator poles formed by a post and a wire wound about the post to form a stator winding, with the stator winding having end turns, a rotor having two rotor poles and configured to rotate relative to the stator and a channel for liquid coolant to flow through the rotor to at least one nozzle, and liquid coolant sprays from the at least one nozzle at least a portion of the stator windings.
