Development of Coupling Analysis Method of Magnetic Field, Mechanism & Control

Shuji MIYAZAKI, Koki YAMASHITA and Daiji ICHISHIMA

We propose a coupling analysis method of magnetic field, mechanism and control based on an equation of motion for magnetic field. Since the magnetic field state is described by the equation of motion, the law of energy conservation is satisfied. In addition, a consistency of elements which is required in conventional coupling analysis method represented by the Finite Element Method（FEM）is not necessary. As a result, the coupling analysis of electromagnetic actuators with a complicated motion pattern is enabled with a higher accuracy compared with conventional one. In this paper, a static magnetic field analysis by using the equation of motion for magnetic field is performed. The result shows a good agreement with the FEM calculation result. Furthermore, it is shown that the coupling analysis of the magnetic field and mechanism under the control is possible from coupling analysis results of a coreless linear motor.
