This paper presents an analysis of the permanent magnet overhang effect for the permanent magnetic actuator. Generally, the overhang is often used to increase the force density in permanent magnet machineries. The overhang is particularly profitable in reducing the volume after increasing the force density per volume when using the overhang effect of the permanent magnet. Therefore, the 3D Equivalent Magnetic Circuit Network Method (3D EMCN) has been used in this paper. According to the plunger position, the flux distribution per overhang length and the holding force are quantitatively compared. Furthermore, an appropriate length of the overhang has been proposed. To confirm the accuracy of the analysis method, the results of 2D FEM and 3D FEM are compared for the basic model.

문제 정의

In general, it is common to perform overhang in order to raise the force density per volume in PM devices, and the research results concerning the quantitative characteristics in linear machines and rotary machines have been revealed [2, 3] Yet, there are few papers for reference that demonstrate quantitatively what the overhang effect is in the PM actuator. Therefore, the precise analysis and investigation performed by this research are necessary. 3D analysis is unavoidable because the increase of the effective flux cannot be suitably considered in 2D analysis.
This paper shows 3D EMCN Analysis considering the PM Demagnetization Curve to analyze the influence in the PM actuator with a PM overhang condition. Furthermore, the influence of the caps in the direction of the z-axis has been analyzed.

제안 방법

To confirm the accuracy of the analysis results using the 3D EMCN, the analysis results for a model without performing the overhang are compared with that using 2D FEM and 3D FEM separately. Fig.
3. To confirm the accuracy of the results for the 3D EMCN, the holding forces for a model, which has no overhang with the cap, are compared through 2D FEM and 3D FEM according to the plunger position.

대상 데이터

The analysis model in this paper is the moving core type in Fig. 1 that looks like the general PM actuator of rectangular parallel type with an internal plunger moving up and down. It also has two caps in the z-axis direction to protect the permanent magnet and inner parts from mechanical shock, dust and other particles.

이론/모형

3D analysis is unavoidable because the increase of the effective flux cannot be suitably considered in 2D analysis. Hence, this paper shows the 3Dimension Equivalent magnetic circuit network method (3D EMCNM) to analyze the overhang structure of the PM actuator. According to the plunger position, the flux distribution per length of the overhang and the holding force are quantitatively compared.

성능/효과

5 presents the holding force using three methods according to the plunger. The analysis error between 3D EMCN and 3D FEM is within 2%, so the results are reasonably confirmed because the analysis error for the FEM is less than 5%. When performing the 2D and 3D analyses, the difference of the holding force is 32% as the stroke is Omm.
