초록
In this paper, advance angle control is described to drive an industrial low voltage SRM(Switched reluctance motor) for a forklift truck by changing velocity and torque. The high current SRM is designed and its phase resistance and phase inductance are very low to inject high current into the phase windings. In this reason, the current has to be built up in the increasing phase inductance part as soon as possible. Therefore, the phase switch must be turned on before the phase inductance increases, and this angle is called as the advance angle. We analyze the changes of the advance angle as its torque and velocity are changed in the real SRM driving experiment. And we propose the way to improve the SRM performance by using the advance angle control.
