Magnetic field finite element analysis and thrust characteristics calculation of a linear and rotary stepper motor

Abstract

This paper analyzes the structure of a new type of linear and rotary stepper motor. The paper establishes the motor's mathematical model of the linear part's thrust, concluding the thrust relationship of the special motor, which provides an effective theoretical basis for designing this motors. It simulates the motor's structure model through analysis and Ansoft software which is a finite element software. The result verifies the effectiveness of the theoretical calculation.
