Linear motor device and magnetic suspension train

Abstract

The invention discloses a linear motor device and a magnetic suspension train; the linear motor device comprises a linear motor rotor (1), a stator winding (2) and a stator, wherein the stator comprises a composite structure formed by a hollow stator (3) and an iron core stator (4); the hollow stator (3) is used for providing forward driving force; and the iron core stator (4) is used for providing forward driving force and upward normal suction force. According to the scheme, the problem that an existing iron core linear motor is too high in normal suction force and is difficult to adjust, and the problem that the reliability is low due to the fact that the normal suction force of the iron-core-free linear motor is too small can be solved, and the effect of improving the reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of magnetic suspension, and in particular relates to a linear motor device and a magnetic suspension train, in particular to a linear motor with adjustable normal force and a magnetic suspension train with the linear motor with adjustable normal force. Background technique [0002] With the rapid development of maglev trains in high-speed rail transit, the requirements for their driving motors are also getting higher and higher. The motor solutions of various countries in the world are mainly concentrated in permanent magnet synchronous and AC asynchronous linear motors. Considering the energy Due to the limitations of power consumption, maximum speed, etc., permanent magnet linear motors are more and more favored by the industry. [0003] Most of the existing permanent magnet drive motors used for maglev trains have iron core structures, which will cause the normal suction force of the motor to be large and...
