In the electric motor with the mobile stator the driving moment transferred by the stator on a
wheel 4 is opposite in a direction to the driving moment which transfers a rotor to a wheel 6. Driving
power is equal to the sum of powers of the stator and a rotor, or

The equation (7) determines the Effect of Force Adaptation: the electromechanical system
provides adaptation of output angular velocity to a variable moment of resistance at a constant input
power of the electric motor.
We will determine the interacting of power parametres out of equilibrium conditions.
On a link 1-4 the unbalanced moment is acting. It is equal to a difference of the driving moment
of the stator and a moment of resistance transferred to the satellite from the carrier
