Abstract
PURPOSE:To detect the output torque of an induction motor instantaneously and correctly, by electrically measuring an inverter current value and the current rotational speed of said induction motor for arithmetic processing. CONSTITUTION:AC power is converted into DC by a converter 1 and then inverted into the required voltage AC by an inverter 2 and the AC output of said inverter 2 controls an induction motor 3. A current detector 4 is interposed between the converter 1 and inverter 2, while the induction motor 3 is fitted with a rotational speed detector 5, and a current value signal In detected by the current detector 4 and a speed value signal detected by the rotational speed detector 5 are inputted to a torque computing element 6 for arithmetic processing of the output torque of said induction motor.
