Apparatus and method for rotating-sensorless identification of equivalent circuit parameters of an AC synchronous motor |
摘要 |
Identification without shaft encoder of electrical equivalent circuit parameters of a three-phase asynchronous motor comprising: -standstill position search of the rotor, so that the d flux axial direction of the rotor is aligned opposite the cc axial direction of the stator; -test signal voltage supply U1d in the d flux axial direction of the motor whereby the q transverse axial direction remains without current; -measuring signal current I1d of the d flux axial direction of the motor; -identification of equivalent circuit parameters of the motor based on the test signal voltage U1d and on the measuring signal current I1d in the d flux axial direction; whereby the rotor remains torque-free. The method used to control electrical drives. An identification apparatus for a synchronous motor and a motor control device comprising the apparatus, whereby identified equivalent circuit parameters can be used to determine, optimize and monitor a motor control.
