The spring reaction is offset by the rotary inertial torque of the cam shaft, and only the friction resistant torque becomes the motor torque during valve lift.

If the condenser gets too hot, the pressure will rise.

Function out of engine or generator following the resistive torque.

The load moment for different types of motors may be corrected by means of a correction factor.

The generator's second part is driven by the energy accumulation device to rotate in the other direction, when the torque from the driveshaft does not exceed the counteracting torque.

Since the resisting moment is usually almost constant, the vehicle behavior is not regular especially during a low-speed motion.

When unlocking a crankshaft to reversely rotate the crankshaft in a direction in which load torque is applied, large unlocking torque is necessary.

As a result, the engine speed is reduced by 50 rpm and the pump torque is reduced by 5%.

In a device of this type the rotation speed of the two stirring systems is automatically adjusted to the prevailing resistance torque.

The corresponding load moment for a predetermined type of motor is determined by means of a reference table stored in a memory or by means of an algorithm.

This has meant, for example, that the diameter of the shaft of the machines has been reduced and, as a consequence, the resistive torque and the actuators.

The resistance torque that is applied to the arm member upon the circumference of the axis by friction accordingly varies with the degree of manipulation vis-à-vis the arm member.

Said method further comprises a step (24, 25) which consists in estimating at least one of the values of the resisting torque (C) and the current (i) in the motor windings.

The present invention pertains to the operating mode of stepping motors, where the moment of resistance (M) temporarily changes fo a substantially equal number of rpm (D).

The device is comprised of a special kinetic resistance electronic unit (31, 32) which emulates with precision the dynamic effect of the mass of the user while controlling the resistance torque.
