Document Type and Number:
WIPO Patent Application WO/2022/236896
Kind Code:
A1
Abstract:
Disclosed in the present invention are an ultra-thin vehicle-mounted magnetic suspension flywheel battery for an electric vehicle and a working method therefor. A motor bracket, an axial magnetic flux motor, a flywheel, and an inner stator, a coil, and a permanent magnet of a five-degree-of-freedom magnetic bearing are coaxially arranged in a housing from top to bottom, and the flywheel consists of an upper layer, a middle layer, and a lower layer which are continuous; an upper annular groove is provided in the middle of a flywheel upper annular layer as the upper layer, and the axial magnetic flux motor is placed in the upper annular groove; an annular inner groove, a middle-layer annular cavity, and a lower annular groove are communicated and jointly used for placing the inner stator, the coil, and the permanent magnet of the five-degree-of-freedom magnetic bearing; the five-degree-of-freedom magnetic bearing comprises an axial magnetic bearing, a repulsive magnetic bearing, a torsional magnetic bearing, and a radial spherical magnetic bearing from inside to outside. By means of combined use of magnetic bearings having different properties, advantage complementation is achieved, the bearing capacity and control precision of support of the magnetic bearing can be improved, the stability of the flywheel can be remarkably improved, and large loss of a control coil due to complex working conditions can also be effectively compensated.
