This stops the rotation of the motor (212).

The parameter depends upon the rotation of the motor.

The rotation sensor detects a rotation position or speed of the motor.

The rotation of the motor during the injection of the medicine (12) is controlled by the control unit (17) according to the amount of rotation of the motor.

At low engine speeds, the supercharger is powered by the motor/generator; at high engine speeds, by the engine.

Thus, the rotation of the motor is translated to rotation of the generator, providing for electrical power generation.

The motor rotation speed (Nm) is reduced as a result of motor (3) rotation speed control by a motor rotation speed-controlling means (Step (S6)).

The rotational speed of the motor-generator (150) is sensed.

A rotational speed sensor detects the rotational speed of an engine.

In the engine functioning, each piston provide four functions in each rotation period of the engine.

The invention can be used to predict engine rotation reversal.

It is also determined that the engine rotation speed needs to be limited to the upper limit value of the engine rotation speed.

The rotational speed detection means detects the rotational speed of the electric motor.

The motor control unit (10) controls the rotation angle of the relieving spindle motor (12) on the basis of the rotation angle of the cutter spindle motor (11).

A swing operation amount (P1) of the swing action of the swing motor (2) is detected, as well as the work pressure (P2) supplied to the swing motor from the hydraulic pump (1).
