Problems solved by technology

Therefore, due to the energy consumption problem during operation, the further increase of the suspension air gap is affected.
On the other hand, due to the small suspension air gap, the train has high requirements on the accuracy of the track, and the error is generally within 2mm, which increases the cost of the track

Embodiment Construction

[0015] The present invention will be described in more detail below with reference to the accompanying drawings.

[0016] combine figure 1 , figure 2 and image 3 , The composition of this embodiment includes a guide rail 1 , an inner pole Halbach array permanent magnet 2 , a levitation coil 3 , an electromagnet core 4 and an outer pole Halbach array permanent magnet 5 . The guide rail 1 is made of soft magnetic material and has an F-shaped structure. The electromagnet core 4 is a soft magnetic silicon steel sheet material, with a U-shaped structure as a whole, and a T-shaped expansion structure at both ends. At the same time, the inner pole Halbach array permanent magnet 2 and the outer pole Halbach array permanent magnet 5 are arranged, and are connected with the guide rail 1 corresponding to the magnetic poles. The inner pole Halbach array permanent magnet 2 is formed by bonding three small permanent magnets in the horizontal direction, wherein the magnetization direct...

Abstract

The invention provides a Halbach array permanent magnet hybrid electromagnetic suspension system which comprises a guide rail, an inner pole Halbach array permanent magnet, a suspension coil, an electromagnetic iron core and an outer pole Halbach array permanent magnet. The guide rail is made of a soft magnetic material and has an F-shaped structure; the electromagnetic iron core is made of soft magnetic silicon steel sheet materials and is of a U-shaped structure, the end of the electromagnetic iron core is of an expanding type, and the inner pole Halbach array permanent magnet and the outerpole Halbach array permanent magnet are arranged at the same time and correspond to guide rail magnetic poles. The suspension coil is wound on the electromagnetic iron core. The system has the characteristics of low power consumption and large levitation air gap and is suitable for the electromagnetic levitation system for the maglev train.

Description

technical field [0001] The invention relates to an electromagnetic suspension system, in particular to an electromagnetic suspension system for a maglev train. Background technique [0002] The maglev train is a new type of non-contact ground rail transportation, which cancels the wheels that traditional vehicles rely on for transmission, thereby realizing non-adhesive traction and non-contact operation. Therefore, it has the characteristics of low noise, low vibration, wide speed range, fast acceleration and deceleration, strong climbing ability, and low maintenance cost. It is also known as an ecologically pure land green vehicle. For the conventional maglev train, the levitation force is all provided by the electromagnet. Since the levitation coil has a certain resistance, the levitation needs to consume a lot of power, so the levitation air gap should not be too large, generally about 8~10mm, otherwise the levitation power It increases proportional to the square of the ...
