Document Type and Number:
WIPO Patent Application WO/2019/053675
Kind Code:
A3
Abstract:
Disclosed is a regenerative braking arrangement for an electrical vehicle. The regenerative braking arrangement includes at least one electrical motor including a casing, a stator mounted on the casing. The stator includes one or more planar (plate-like) stator elements extending from the casing. The motor also includes a rotor having a shaft and a one or more plate-like rotor elements attached to the shaft and magnetic bearings coupled to ends of the shaft. The one or more planar (plate-like) stator and rotor elements include electrical winding coil arrangements having a regenerative braking coil arrangement. The regenerative braking arrangement also includes a motor control arrangement having a rotor excitation unit and a switching control unit for selectively energizing the regenerative braking coil arrangement for generating electrical power from the at least one electrical motor when regenerative braking is applied in operation to recharge the rechargeable battery arrangement of the electrical vehicle.
