Summary of the invention

In order to overcome above-mentioned defective, the purpose of this utility model provides and a kind ofly need not that rectification-inverter just can change that output voltage, electromagnetic noise are little, long service life meet excitation synchronous generator.

For achieving the above object, the technical solution of the utility model is:

A kind of novel electricity generator, it comprises main shaft, be fixedly mounted on the main shaft rotor and around the stator that is arranged on peritrochanteric, described stator by Bearing Installation on main shaft, described stator comprises organic block, be fixed with stator core on the support, stator winding is installed in the slot for winding of stator core, also be equipped with optical cable in the slot for winding with twining, described rotor comprises two pawl pole plates that are oppositely arranged, be installed with permanent magnet and rotor core between described two pawl pole plates, described rotor core comprises the first iron leg core and the second iron leg core, twines magnet exciting coil on the described rotor core, permanent magnet and rotor core be evenly distributed on main shaft around.

On the described main shaft adapter sleeve is installed, described two pawl pole plates are fixedly mounted on the two ends of adapter sleeve respectively.

The described first iron leg core and the second iron leg core adopt short-circuited conducting sleeve to be connected, and two sections skew directions of the first iron leg core and the second iron leg core are opposite, and separately a stator tooth distance of skew 1/2.

Described short-circuited conducting sleeve width is 9-11mm.

Rotor slot-pitch staggers half in the middle of the described first iron leg core and the second iron leg core.

Described optical cable is laid between stator core and the stator winding near stator core.

The usefulness of technique scheme is:

The method that the utility model adopts magnet exciting coil to change the logical quantity of magnetism is adjusted output voltage and reactive power, and action is fast, the output voltage adjusting range is big, can satisfy the requirement of multiple working condition; The rotor core of its use simultaneously can effectively reduce motor electromagnetism noise.

The stator of its use of the utility model has adopted the profile fiber temperature sensor system, has important and practical meanings to taking precautions against generator unit stator winding hot stall.

Below in conjunction with the drawings and specific embodiments the utility model is further described.
