Bilateral Flux Switching Permanent Magnet Linear Motor

Abstract

The invention discloses a bilateral magnetic flux switching permanent magnet linear motor, which comprises a bilateral secondary stator and a primary mover arranged between the stators, the primary mover includes six primary mover units, and the primary mover There is a connecting bridge between the subunit and the primary mover unit, each primary mover unit includes two H-shaped magnetic cores, and permanent magnets are arranged between the two H-shaped magnetic cores; the spaced on the secondary stator A number of secondary teeth are formed, a secondary slot is formed between the secondary teeth, a yoke is formed at the bottom of the secondary slot, and the H-shaped magnetic permeable core opposite to the secondary tooth Magnetic teeth are formed on the top, and winding installation slots are formed between the magnetic teeth on the same side; the bilateral secondary stator is used as a fixed part, the primary mover is a moving part, and the primary mover is used to make a straight line between the bilateral secondary stators. Movement, the motor that constitutes the bilateral flat plate structure. The linear motor has the advantages of high utilization rate and low flux leakage.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a double-sided magnetic flux switching permanent magnet linear motor. Background technique [0002] At present, with the development of industrial technology, the use of linear motors in rail transportation, vertical lifting and other fields has become more and more a hot spot of application technology. This is due to the low efficiency of traditional rotary motors relying on mechanical transmission devices, which cannot meet the requirements of high-efficiency operation in terms of various performances. Compared with traditional rotary motors, linear motors omit mechanical transmission devices and directly generate electromagnetic force. , has the advantages of high thrust density, small loss and low noise. Therefore, using a linear motor instead of a rotary motor can overcome the above-mentioned shortcomings of the rotary motor in the above-mentioned application occasions and i...
