PURPOSE:To readily recognize asymmetrical drive or transient phenomenon by employing a simulator represented by a physically readily understandable configuration for an AC circuit machine. CONSTITUTION:An input from the first equivalent circuit having 3-phase stator winding resistors 10-12, leakage inductances 1-2 and a voltage source is converted via a coordinates converter 172 for applying stator currents iU-iW on a rotor coordinates as a current source into current reference values ids* iqs*, and inputted to the second equivalent circuit having resistors and inductances through voltage/current converter 173. Torque is calculated by ids*, iqs*, id, deltaiq by a torque calculator 177. This torque value is detected as an angular velocity omega, converted into a pulse train proportional to by a V/F converter 178, a rotor position theta is provided by a counter 179, sintheta and costheta are outputted via ROM18, and necessary signal is applied to the converters 171, 172. |
