| Abstract |
Two methods to identify the electrical parameters and the magnetization curve of a voltage source inverter-fed induction motor (IM) at standstill will be presented.
A special advantage of these methods is that the differences between the reference voltage values and the real phase voltage values caused by the unknown switching times of the PWM-inverter will be completely suppressed. Therefore a measurement of the phase voltage is not necessary and the parameters of the induction motor can be estimated with a high accuracy. Thus, no addltional hardware is necessary and therefore this identification rnethod is a good solution for use in commercial self-commissioning drives. |
