摘要
The identification method entails assuming a standstill position of a rotor, and infeeding an equidirectional test signal voltage feed in the stator axis direction of an asynchronous motor. Signal currents are measured. The equivalent circuit parameters of the asynchronous motor are identified based on the test signal voltages and the measured signal currents. The test signal feed into the asynchronous motor takes place in such a manner that the rotor remains torque-free. Independent claims are also included for the following: (1) an identification apparatus; and (2) a motor control device.
