Abstract
PURPOSE: To form an induction motor controller which can consume required minimum amount of current by controlling effective magnetic flux.
CONSTITUTION: A speed controlling amplifier 72 calculates a torque T from the deviation between the output of a rotating speed setting control resistor 71 and the output of a speed detector circit 79, an arithmetic circuit 73 calculates secondary interlinking magnetic flux ϕ2 and slip frequency SWe from the output of an effective magnetic flux setting control resistor 70 and the torque T, and an arithmetic circuit 74 calculates primary voltage e1 and motor primary frequency We from the secondary interlinking magnetic flux ϕ2 and slip frequency SWe. A primary voltage control amplifier 68 controls the phase of a converter 62 in response to the deviation between the primary voltage e1 and the output of a voltage detector circuit 66, and primary frequency control amplifier 75 control the phase of an inverter 63 in response to the deviation between the primary frequency We and the output we of a frequency detector circuit 78.
