摘要：PURPOSE:To reduce the cost and the size of an AC servo motor and to improve the reliability of the motor in an AC servo motor controller using a resolver as a rotating angle detector by providing a microprocessor to reduce the number of components of the circuit. CONSTITUTION:A signal is generated from a microprocessor 6 at every predetermined time, input to a resolver exciter 7, which generates a sinusoidal wave sin theta and cos theta synchronized with the input signal, and input to a resolver. The resolver generates a signal of the phase responsive to the rotating angle to an amplifier 1. The microprocessor 6 calculates a command current value from the present rotary angle of the resolver and the present speed, compares it with current feedback values ifu, ifv, ifw of phases applied through an A/D converter 11, and a time width for controlling a control element is set to timers 8, 9, 10.
