Problems solved by technology

[0003] In the case of a conventional synchronous generator using a permanent magnet, if the pole rotor provided with the permanent magnet is rotated, the repulsive force received from the iron core when the permanent magnet passes through the iron core of the stator coil, The influence of the attractive force hinders the rotation, the rotation load torque of the pole rotor increases, and the load current of the driving motor that rotates the pole rotor increases significantly. As a result, the power consumption for rotating the pole rotor increases significantly. , the problem that the power generation efficiency of the generator is greatly reduced
