Title:
VEHICLE-MOUNTED FLYWHEEL BATTERY USING FIVE-DEGREE-OF-FREEDOM HYBRID MAGNETIC BEARING
Document Type and Number:
WIPO Patent Application WO/2019/019244
Kind Code:
A1
Abstract:
Disclosed by the present invention is a vehicle-mounted flywheel battery using a five-degree-of-freedom hybrid magnetic bearing as a magnetic suspension support; the five-degree-of-freedom hybrid magnetic bearing is arranged at the exact middle of an inner portion of a sealed vacuum chamber; a magnetic bearing rotor is coaxially and tightly sleeved outside of a rotating shaft of the magnetic bearing at the exact middle of the magnetic bearing; a tension disk is tightly sleeved outside of the exact center of the magnetic bearing rotor in the axial direction, and a flywheel is fixedly sleeved outside of the tension disk; a stator pole is wound with a radial control coil, and an axial stator is internally provided with an axial control coil; at the exact center outside of a top surface of an outer casing is a motor/generator, a rotating shaft of the motor extending from top to bottom into the outer casing and being coaxially and fixedly connected to an upper end of the rotating shaft of the magnetic bearing; by integrating the tension disk and the flywheel into one unit, the axial length of the flywheel battery is further shortened, and the gyroscopic effect is effectively suppressed; the five-degree-of-freedom hybrid magnetic bearing integrates two single-piece three-degree-of-freedom hybrid magnetic bearings together, and is distributed on two sides of the tension disk by using a manner of mirror-symmetry, having high control precision.
