IPC: H02P21/16
Filed: 1993-10-15
Abstract: PURPOSE:To enable highly accurate control on position, speed and torque, including those in proximity to 0 deg., by estimating magnetic flux position from inductance based on a phenomenon in which inductance varies depending on the positional relation between winding and motor magnetic flux. CONSTITUTION:A.c. voltage is superposed on an output voltage command value of an inverter 1. The motor 2 current component that flows according to the result of the superposition is detected using a current component detector 7, and leakage inductance of the motor 2 winding is determined from the A.c. voltage and current. Then magnetic flux position (rotational angle) phi1 is estimated from inductance using a phenomenon in which inductance varies depending on the positional relation between the motor 2 winding and the motor 2 magnetic flux. The phase of the inverter 1 output voltage and the exciting component and torque component (equivalent to secondary current) of the motor 2 current, are controlled according to the estimated magnetic flux angle phi1. This makes possible highly accurate control on position, speed and torque, including those in proximity to zero speed.
