【Abstract】 A new method was presented for the digital AC servo system without Hall element current sensor. This method base on vector space PWM. The motor phase currents can be got by a resistance which is simple and cheap. The servo system design method can reduce the cost of AC servo system, and optimize the structure of AC servo system.更多还原
