The system software involves five main modules: initialization module, phase-changing module, current-regulating module, speed-regulating module and timer interrupt module.
软件分为五块：主程序中的初始化模块、换相子程序模块、电流调节、速度调节子程序模块，定时器中断程序模块。
Remark: every wire of the three-phase five-wire system is clearly indicated on the front panel.
注：每一块面板清晰显示三相五线制电源的母线、支线。
Mathematical model of the system, included the current control circuit, power driving circuit and five-phase hybrid stepping motor is established.
