Generally, the rotor of a vehicle generator is driven by an engine, and the cooling fan of the generator is fixed to this rotor. Therefore, the air volume generated by the cooling fan increases in proportion to the rotation speed of the generator rotor, so for example, if the cooling fan is
If the generator is driven at twice the rotation speed, twice the amount of air can be obtained, and therefore twice as much heat can be taken away, so the output of the generator can be increased accordingly.

In a heavy-duty generator, the temperature rises at about 3.00 ORPM! 13, but this temperature can be reduced by increasing the air volume.

When the engine starts and the dual-purpose alternator is driven, an output voltage corresponding to the rotation speed is induced in the armature winding (2), and the rectified output voltage is supplied to the battery (4) or kl and a load (not shown). Also, at the same time, the above armature winding (2)
The output voltage induced in the stator winding (8) of the induction motor is
and energizes the magnetic joint. By energizing the stator winding (8), eddy current is generated at the eddy current joint between the stator and rotor (9) of the induction motor, and the electromagnetic force accompanying the generation of eddy current causes the rotor (9) to ) is driven to rotate.

。If the number of poles of the stator winding (8) of the motor is P2, the relationship between the synchronous speed Nzrpm and the frequency f1 is N2 - tsubo ji1]2 and the force gill number 11, so the electric uJ machine for the synchronous speed Nl of the generator ] The ratio of speed N2 is N2:NI:PI:P2, and if everything is ignored, the rotor (9) of the motor is approximately P + /P doubled, 1g, and connected to the rotor (9). The air volume of the cooling fan (7) is doubled by P l/P. For example, if the generator is configured with 12 poles and the electric IWJ machine is configured with 4 poles, the motor rotor (9) rotates at about three times the speed of the generator rotor, and therefore three times as much cooling air can be obtained.

従来のものに比して大きなものか得られる利点がある。As described above, in this invention, a part of the alternating current output of an alternating current generator is input, and a magnetic coupling is formed by using a stator having a number of poles less than one of the number of poles of the alternating current generator and biasing the poles of this stator. A power generator consisting of a rotor that is rotationally driven is provided, and a generator cooling fan is provided on the rotor of this power mJ machine, so the number of poles of the generator and the number of poles of the motor can be adjusted arbitrarily. By setting this setting, the rotation speed of the cooling fan can easily be more than three times the rotation speed of the generator, and the air volume of the cooling fan can be increased. It has the advantage of being bigger than other things.
