A coaxial asynchronous motor drive system, including a speed reducer, an electric motor and a main housing, and further including a motor controller, wherein the electric motor and the speed reducer are connected to form a motor reducer assembly and mounted inside the main housing, and the motor controller is fixed to the main housing and connected to the motor reducer assembly. The system reduces parasitic loss of an auxiliary motor drive system of a battery electric four-wheel-drive vehicle and increases the range per charge of the vehicle, and the compact and integrated coaxial motor drive system facilitates maximum utilization of available space of the vehicle.

Coaxial asynchronous electric drive system

A corona-resistant enameled round wire and preparation method of making such which is suitable for electric vehicle motors and has a copper conductor and an insulating layer. The insulating layer clads the copper conductor and has in sequence from inside to outside, a corona- resistant polyamideimide coating, a corona-resistant special resin coating, a corona-resistant polyimide coating, a corona-resistant modified silicone resin coating, and a corona-resistant polyamideimide coating.

Corona-resistant enameled round wire and preparation method therefor

A winding arrangement provided on a stator of an electric machine. The winding arrangement includes at least four windings. A first winding and a second winding occupied a first subset of slots; and a third winding and a fourth winding occupied a second subset of the slots. The first subset and the second subset of the plurality of slots are adjoined to each other. A span between two adjacent slots concerning the first winding, the second winding, the third winding, and the fourth winding is chosen from a full-pitch, a short-pitch, and a long-pitch to result in the winding arrangement where the first subsets in a first half of the slots is diagonal to the second subset in a second half of the slots, and the second subset in the first half of the slots is diagonal to the first subset in the second half of the slots.
