Isolate a gap in the periphery of described new magneto (the floated bearing of bearing) and make non magnetic closure, its inwall connects with the stator of motor, punch thereon the conductor wire of armature coil is drawn, and the space sealed, to be evacuated in the non magnetic closure then, become energy storage motor (being equivalent to energy accumulation device for fly wheel) like this.When powering to motor, described motor serves as DC motor, can make its rotor high-speed rotation and capacitation, when the conduction line end external load of armature coil, described new magneto serves as the outside energy supply of DC generator, and in the energy storage phase, the conduction line end of armature coil is unsettled.

The above armature coil can also be made into hollow tubular with non-magnetic conductive material, avoids described lug then and described non magnetic insulation strip is enclosed within outside the described magnetic conduction annulus.

The effect that the utility model is useful:

1, described new magneto is compared with existing direct current machine, absence of commutator, and brushless, the iron core that no silicon steel sheet builds up, so simple in structure, cost is low;

2, eddy current loss and the magnetic hysteresis loss in the described new magneto, it is iron loss, only occur in motor shutdown process or the speed regulation process, (motor leads to steady direct current as if motor stabilizing work, generator input torque and rotating speed are constant) time, being in the armature coil in the stationary magnetic field is steady direct current, so there is not iron loss, obvious energy conservation, efficient is high;

3, because there is not iron loss when brushless, described new magneto steady operation, thus can the long time of continuous operation, and long service life;

4, only change the size of the electric current in the described new magneto armature coil, just can change the rotating speed of rotor, very easily realize speed governing, this makes speed regulator very simple, need not have the existing motor variable-frequency speed-regulating device of complex and expensive now.

5, if described new magneto uses floated bearing, and described new magneto brushless, absence of commutator, rotor rotate in a vacuum, thereby there is not a mechanical friction energy loss, and because described advantage 2, so it is described new magneto is made energy storage device, more superior than devices such as existing flywheel energy storage, inductance coil energy storage, batteries to store energy, compressed-air energy storages.
