(57) Abstract Manner and the device which control the electric induction machine which has the special coil in order to generate the power of torque and cross direction together are disclosed. In this device, strength and direction of power of the cross direction operation to the rotor of the induction machine are controlled through the electric current of the control winding. The torque formation component of strength and direction and Drive electric current of magnetic flux of the machine which is generated in this purpose, by the Drive coil is detected. From these parameters, value of desire of control current vector through the decoupling expression in the frame of reference which turns attendant upon machine magnetic flux it is calculated accurately. Value of desire of control current vector becomes conversion possible in fixed stroma mark system of the control winding depending upon vector revolution, magnetic flux angle and the fixed angle which show the position of the wire-wound axis of Drive and the control winding. Electric current of the desire in the individual wire-wound string is decided as the result of this control current vector. These electric currents are impressed in the coil by the current supply source device. You can list the dot that it is control possible and very it is control possible accurately as an advantage of this invention, power from the side operation to the rotor regarding the machine of some state regarding the part of the weak magnetic field in especially stationary state. This is shown by all magnetic powers, Maxwell power and Lorentz''s force and Drive magnetic flux and detects the torque formation electric current component operation in the machine.
