Abstract

PURPOSE:To raise the maximum speed of an induction motor to twice without decreasing the control performance by providing a simulation circuit of a bouble speed motor. CONSTITUTION:A simulation circuit 14 of a double speed motor inputs a torque reference signal from a speed controlling arithmetic amplifier 10 and a gap magnetic flux reference signal, performs a simulation calculation and produces a spacial phase difference signal of current reference, primary and secondary currents. A phase signal generator 15 inputs a spacial phase difference signal between th 1/2 rotation phase signal fed from a rotation phase signal generator 9 and primary current flowing through the primary coil of and secondary current flowing through the secondary coil of a motor and produces a motor current phase signal. The spacial phase difference of the torque, gap magnetic flux, current, primary current, secondary current of composite relation are simulated, and the spacial phase difference of the current, primary current and secondary current are controlled with the torque and gap magnetic flux as references.
