Abstract

The invention discloses a 12 / 6-pole hybrid rotor structure magnetic suspension switched reluctance generator and a control method thereof. A stator of the generator has 12 tooth poles, each stator tooth pole is wound by a winding, a rotor is formed by axial superposition of 6 tooth poles and a disc and has no windings. The pole width of salient poles of the generator stator is the same as that of salient poles of the rotor. The structure enables inductance of each phase to have a 1 / 2 cycle to be located in a flat area of the bottom, 1 / 4 to be located in a rising area, and 1 / 4 to be located in a falling area. In power generation operation, only three phases in a mechanical structure which form 120 degrees with one another and whose inductance is located in the flat area and the rising area are conducted, each phase independently controls generation of suspension force and provides excitation for a power generation stage, and the rest three phases located in the inductance falling area generates electricity with follow current. The novel generator integrates a radial magnetic bearing and a switched reluctance motor, rotor pole braking torque is large, generated output is large, influence of suspension phase current on power generation phase current is small, and the radial load capacity is high.

Description

technical field [0001] The invention relates to a magnetic suspension switched reluctance generator with a hybrid rotor structure and a control method thereof, belonging to the field of magnetic suspension switched reluctance generators. Background technique [0002] The magnetic levitation switched reluctance motor combines the magnetic bearing technology with the switched reluctance motor to realize that the magnetic bearing and the switched reluctance motor share a set of windings. Running without bearings. Due to the similarity between the structure of the maglev switched reluctance motor and the switched reluctance motor, following the research on the electric operation of the maglev switched reluctance motor, expanding the power generation operation mode of the maglev switched reluctance motor has become a research hotspot. [0003] The excitation and power generation process of the traditional maglev switched reluctance generator is controlled periodically and time-s...
