Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] Such as figure 1 As shown, a flux switching type transverse flux permanent magnet linear motor includes two stators 1 and at least one mover 2, and the two ends of the mover 2 are respectively placed in the two stators 1. In this embodiment, the two stators 1 are arranged symmetrically at both ends of the mover 2 . In the figure, two stators 1 and one mover 2 are schematically shown. Of course, the number of movers 2 is not limited thereto, and can be increased according to actual conditions. For example, when a three-phase motor is needed, we can add two movers at a position parallel to the mover 2 shown in the figure, so that the three-phase motor can provide power.

[0034] Such as figure 2 As shown, t...

Abstract

The invention relates to a flux-switching transverse flux permanent magnet linear motor which comprises two C-shaped stators and at least one rotor. Two ends of each rotor are arranged in the two stators respectively, a plurality of strip teeth are arranged on three faces of the inner walls of the stators, the rotors comprise connecting plates, three projecting pole structures are arranged at two ends of the connecting plates respectively, each projecting pole structure comprises two U-shaped teeth and two L-shaped teeth, the two U-shaped teeth are arranged at intervals, the two L-shaped teeth are arranged on one opposite side of the two U-shaped teeth respectively, the two L-shaped teeth and the U-shaped teeth adjacent to the L-shaped teeth are opposite, permanent magnets are arranged among the L-shaped teeth and the U-shaped teeth and between the two U-shaped teeth respectively, and each permanent magnet and unilateral U-shaped teeth and / or L-shaped teeth of two sides of the permanent magnet are encircled through an armature winding. The flux-switching transverse flux permanent magnet linear motor solves the problems of high permanent magnet consumption, serious magnetic flux leakage and poor heat dissipation effect of a traditional flux permanent magnet linear motor, and is simple in structure, easy to mount and high in reliability.

Description

technical field [0001] The invention relates to a motor, in particular to a magnetic flux switching type transverse flux permanent magnet linear motor. Background technique [0002] The linear direct drive motion system eliminates the need for complex mechanical conversion devices. The system has a simple structure, reliable operation, fast response and high control precision. Electromagnetic ejection system, electric actuation system, transportation system, etc. With the development of modern advanced equipment, these fields have put forward higher and higher requirements for linear direct drive motion systems, including high force density, high reliability, and strong fault tolerance. As the core component of the linear direct drive motion system, the linear motor has always been the preferred electric drive solution for the linear direct drive motion system, and it is also an effective means to solve the above problems. In the traditional transverse flux permanent magne...
