Problems solved by technology

[0002] In the various existing linear motors, the armature windings inevitably have ends, but in the actual operation process, the ends of the armature windings do not participate in the electromechanical energy conversion, and the ends generated when the current flows through the ends The magnetic field will have an adverse effect on the operation of the motor, and the existence of the end of the winding will also lead to an increase in the weight and volume of the motor and a decrease in power density

Embodiment approach 1

[0020] Combine Figure 1~5 The present invention proposes a switched reluctance linear motor with high power density. In terms of the structure of the motor main body, it is the same as the existing traditional switched reluctance linear motor. It is composed of a salient pole structure with armature windings. The primary and salient pole structure of the secondary, the supporting structure between the primary and the secondary, and the position sensor. The main difference lies in the specific structure of the primary and secondary. The specific structure is as follows:

[0021] (1) Primary structure. The primary iron core 1 is a flat plate structure; a plurality of protruding primary main poles 2 are installed on the surface of the primary iron core 1 opposite to the secondary, and the primary main poles 2 are evenly distributed along the moving direction of the secondary; on the primary iron core 1, each Protruding primary auxiliary poles 3 are installed on both sides of the ...

Embodiment approach 2

[0035] On the basis of Embodiment 1, the primary core 1, the primary main pole 2 and the primary auxiliary pole 3 are integrally processed by ferromagnetic materials.

[0036] The secondary core 5, the secondary main pole 6 and the secondary auxiliary pole 7 are integrally processed with ferromagnetic materials.

The switched reluctance linear motor comprises a primary structure and a secondary structure; a supporting structure is located between the primary structure and the secondary structure; the primary structure comprises a primary core, primary main poles, primary auxiliary poles and armature windings; the primary main poles are uniformly mounted on the primary core in the motion direction of the secondary structure; primary auxiliary poles are mounted on two sides of each primary main pole; the armature windings are winding coils respectively wound on each primary main pole; and the secondary structure comprises a secondary core, secondary main poles and secondary auxiliary poles, wherein the secondary main poles are arranged in the motion direction of the secondary structure and mounted on the secondary core, the number of the secondary main poles is an even number, and the secondary auxiliary poles are uniformly arranged at two ends of each secondary main pole. The armature windings of the linear motor are high in utilization ratio and power density.

Description

Technical field [0001] The invention relates to a motor, specifically a linear motor. Background technique [0002] Existing various linear motors, the armature winding inevitably has an end, but in actual operation, the end of the armature winding does not participate in the electromechanical energy conversion, the end generated when the current flows through the end The magnetic field will adversely affect the operation of the motor, and the existence of the winding ends will also cause the increase of the weight and volume of the motor, and the decrease of the power density. Summary of the invention [0003] The object of the present invention is to provide a high-power density switched reluctance linear motor that fully utilizes the end of the motor armature winding and further improves the operating performance of the switched reluctance linear motor. [0004] The purpose of the present invention is achieved as follows: [0005] The present invention is a switched reluctance li...
