Abstract

The circuit is designed to control the operating torque of the motor. It has a device for generation of a stator current command for the n-th phae, which satisfies a specified equation ing the number of phases, an integer, a self-inductance of the rotor winding, neutral inductance between the stator and rotor windings, angle of flux of rotating magnetic field, intensity of rotating magnetic field and a constant. There are circuit devices which respond to the stator current command and cause the appropriate alteration in the current in the n-th stator winding.
