Abstract
PURPOSE:To stably control the torque of an induction motor from low to high speeds by controlling the current or voltage of each phase with a current control mode when the motor speed is lower than a predetermined value and with a voltage control mode when it is higher than the value. CONSTITUTION:A pulse signal based on the revolution of 2-pole 3-phase induction motor 5 is, for example, counted by a reversible counter 7. The interrupt input terminal 23 of a computer 10 is triggered with a pulse generated from a sample pulse generator 8, and the content of the reversible counter 7 is read. Then, a program control unit 11 executed the next program. When the program is executed by the program control unit 11, each phase is controlled with current control mode when the motor speed theta is lower than the base speed thetaB in (rsIOB)<2>+[lmIOBthetaB+(lmrr/ lr+rs)I2m]<2>=E<2>-alpha<2>, where rs, rr, lr, lm, IOB represent constants determined by the induction motor, I2m, E are constants determined by the power source, and alpha is constant, and each phase is controlled with voltage control mode when the theta is higher than thetaB when the step is proceeded.
