Abstract

PURPOSE: To control the characteristic of an induction motor flexibly in accordance with the torque characteristic required by the load, by controlling freely the magnitude of the primary current and the phase angle of the primary current corresponding with the secondary flux upon the command level.
CONSTITUTION: Primary currents in U, Y, W phases are controlled respectively with reference to the output from the sample-hold circuit 35, the output from the sample-hold circuit 36 and the output from the adder 37 or -ilU× -ilV×. Consequently the magnitude of the primary current in the induction motor 10 is controlled in proportion with il× while the phase angle θ of the primary current against the secondary flux is controlled in proportion with θ×.
