The magnetic levitation switch reluctance flywheel motor comprises an outer rotor iron core (1) and a stator iron core (4), wherein the outer rotor iron core (1) and the stator iron core (4) are nested in sequence in a concentric manner; the outer rotor iron core (1) comprises a salient pole rotor (2) and a cylindrical rotor (3) in an axial recombination manner; eight rotor salient poles are arranged on the inner wall of the salient pole rotor (2) at equal intervals; each rotor salient pole has no winding; twelve stator salient poles (5) are arranged on the outer wall of the stator iron core (4) at equal intervals; and each stator salient pole is wound by a set of stator windings (6). By adoption of the embodiments of the magnetic levitation switch reluctance flywheel motor and the decoupling control method, the decoupling control on an electric / power generation function and a radial levitation function can be realized; the flywheel rotor strength can be enhanced; the size of the overall machine can be reduced; the dynamic characteristics and the stability of the system are improved; and the high-adaptivity characteristic of the magnetic levitation switch reluctance flywheel motor is further performed.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation motors, in particular to a magnetic levitation switched reluctance flywheel motor and a decoupling control method. Background technique [0002] The magnetic levitation switched reluctance motor generates a controllable levitation force acting on the rotor by changing the original magnetic field distribution of the switched reluctance motor, thereby suspending the rotor in space. On the basis of retaining the performance advantages of the switched reluctance motor, Further eliminates the friction loss caused by mechanical bearings, and does not require lubrication devices. It can be operated by electric or power generation at high-speed and ultra-high speed, and has broad application prospects in many fields such as industry, chemical industry, biology and military industry. Using the magnetic levitation switched reluctance motor as the flywheel motor can effectively reduce the volume...

Problems solved by technology

However, when the composite rotor is running with load, it is easy to increase the axial length and the volume of the whole machine, which affects the mechanical strength of the system and limits the increase of the critical speed, which is not conducive to the high-speed adaptability of the magnetic levitation motor.
