PROBLEM TO BE SOLVED: To solve the problem that energy saving cannot be achieved since power for power consumption increased by a rotational load of a generator becomes more than generated power.SOLUTION: When an electric motor is rotated, it becomes a generator. Therefore, in the case where two electric motors are connected by coupling, one is used as a generator and the other is used as an electric motor, an energy-saving generator can be provided. By twisting either an iron core 1 or a magnet 4 (permanent magnet or electromagnet), cogging of the generator is suppressed. By holding the iron core 1 between the magnets 4 and 6 (permanent magnets or electromagnets), magnetic forces applied to the iron code are made equal between the inner magnet 4 (permanent magnet or electromagnet) and the outer magnet 6 (permanent magnet or electromagnet). Therefore, a rotational load is reduced. By increasing the iron core outside or inside, a mechanical loss caused by connection of the coupling is reduced and the size is made compact. |
