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

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.lt 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.
