Abstract:
A propulsion system includes an electric propulsor and a gas turbine engine. The propulsion system also includes an electric machine coupled to a rotary component of the gas turbine engine generating a voltage at a baseline voltage magnitude during operation of the gas turbine engine. An electric communication bus is provided electrically connecting the electric machine to the electric propulsor. The propulsion system additionally includes a means for providing a differential voltage to the electric propulsor equal to about twice the baseline voltage magnitude.
Abstract:
An apparatus includes a case (19), a motor (MG1), a gear mechanism, a lubrication mechanism, and a cooling mechanism. The motor (MG1) and the gear mechanism are housed in the case (19). The gear mechanism includes a specified gear (46) and a first gear (40). A vertical lower section of the first gear (40) is positioned above a surface of the oil. The lubrication mechanism lubricates the gear mechanism by the oil thrown up by the specified gear (46). The cooling mechanism includes an oil pump (37) and a pipe (58). The oil pump and the pipe (58) supply the oil reserved in the case (19) to the motor. The pipe (58) is located above the first gear (40). The pipe (58) has a hole (62), and the oil is discharged from the hole (62). The hole (62) is positioned above the first gear (40). A normal line direction of the hole (62) differs from a vertically downward direction. The first gear (40) does not overlap the normal line direction.
Abstract:
A hybrid drive module including: a torque converter with a cover, an impeller and a turbine; a rotor for an electric motor; a hub non-rotatably connected to the rotor and the cover and including a circumferential surface and a plurality of protrusions extending radially outward from the circumferential surface; and an end plate disposed between the plurality of protrusions and the rotor and engaged with the end plate and the rotor. The plurality of protrusions is formed of a material forming the hub and restrains the end plate and the rotor, with respect to the hub, in an axial direction.
Abstract:
Aspects of the present invention relate to an active noise system, a controller for an active noise system, a method and a hybrid electric vehicle. The invention relates to use of an active noise system for providing noise when an ICE is not active.
