Abstract

PURPOSE: For obtaining the accurate values of load torque without any time delay, to provide a circuit for copying the acceleration or deceleration signal generated when speed instruction value for the motor controlled in speed charges.
CONSTITUTION: When deviation value ΔNREF from the reference value of speed instruction values is fed, a copying circuit 33 generates the acceleration or deceleration signal Ia required to change speed by the value of ΔNREF. Load current signal is obtained by the subtraction of the output Ia of said copying circuit 33 for generating acceleration or deceleration current signal and loss current Iloss from the current signal I actually flowing in a rotor by a subtracting circuit 34, and multiplied by torque constant Kt for obtaining load torque Gr by means of a multiplying circuit 35. Speed compensation value NREF(T) is computed from said load torque Gr and rolling capacity F by a speed compensating arthmetic circuit 30.
