Abstract

The invention provides a permanent magnet levitation linear electromagnetic propelling system and relates to a motor, in particular to a magnetic levitation linear motor. The system aims at solving the problems that a magnetic field formed by superconducting magnets is serious in flux leakage, the magnetic field shielding difficulty is large, and the levitation control difficulty of the normal conducting magnetic levitation technology is large. The system comprises a drive control subsystem and a linear motor subsystem. The drive control subsystem comprises a power converter unit and a controller. The linear motor subsystem comprises a stator and a rotor, the stator is fixed to the ground, and the rotor is fixed to a prying vehicle and moves relative to the stator; the stator comprises a levitation-guide winding and a propelling winding; the levitation-guide winding a unilateral levitation-guide primary unit; and the propelling winding comprises a bilateral propelling primary unit. A special levitation and guide control device is not needed; and no leaking magnetic field exists on a vehicle.

Description

technical field [0001] The invention relates to a motor, in particular to a magnetic levitation linear motor. Background technique [0002] The existing high-speed maglev linear electromagnetic propulsion system can be divided into two categories: normal conduction type and superconduction type. The constant conduction type is also called the constant conduction magnetic suction type, represented by the German high-speed constant conduction maglev train transrapid, which uses the principle of electromagnetic attraction of ordinary DC electromagnets to suspend the train, and the suspended air gap is small, generally about 10mm. The speed of the conventional high-speed maglev train can reach 400-500km per hour, which is suitable for long-distance rapid transportation between cities. The superconducting magnetic levitation train is also called superconducting magnetic repulsion type, represented by MAGLEV in Japan, which uses the strong magnetic field generated by superconduct...
