Title:
ELECTRICAL MOTOR ARRANGEMENT FOR ELECTRICAL VEHICLES
Document Type and Number:
WIPO Patent Application WO/2019/053669
Kind Code:
A3
Abstract:
Disclosed is an electrical motor arrangement for an electrical vehicle. The electrical motor arrangement includes at least one electrical motor. The at least one electrical motor includes a casing, a stator mounted on casing, a rotor including a rotor shaft and magnetic bearings coupled to ends of rotor shaft. The stator includes one or more radial plate-like stator elements extending from the casing, wherein each of the stator elements includes a central hole. The rotor shaft is disposed within the central hole of each of the one or more plate-like stator elements. The rotor includes one or more radial plate-like rotor elements attached to rotor shaft. Moreover, principal planes of one or more radial plate-like stator and rotor elements are arranged mutually to abut with a magnetic separation gap therebetween, and one or more radial plate-like stator and rotor elements are arranged to have electrical winding coil arrangements disposed thereon. Optionally, alternatively, the at least one electrical motor is implemented so that its rotor encircles its stator, wherein the stator is centrally implemented within the at least one electrical motor.
