四相双4拍永磁爪极步进电机稳态运行仿真

永磁爪极步进电机是一种将脉冲信号转换成相应角位移的控制电机，它具有特殊的爪极结构，爪极将定子绕组产生的轴向磁场转化为沿气隙圆周径向异极排列的磁场。本文以四相双4拍运动方式为例，采用四阶龙格－库塔法对永磁爪极步进电机稳态运行情况进行数字仿真分析，得到不同频率下电机相电流仿真波形。

The Steady State Simulation of 4-phase Double-four Step Claw Pole

The claw pole permanent magnet stepping motor is a special motor that transforms the electric pulse into corresponding angle displacement. Because of the particularity of claw pole structure, the axial magnetic field produced by the stator winding is transformed into the diametric one along the circle of air gap. Taking a 4-phase double-four step operating type for example, the paper simulates the steady state of the motor by use of 4-order Runge-Kutta method, the simulated waveforms of the currents under the different frequencies are acquired consequently.
