Taiwan's electricity consumption during summer increases significantly owing to the abnormal climatic changes caused by the greenhouse effect. An expedient strategy to develop a high-efficiency magnetic power generator can address the existing problem of power shortage in Taiwan. The magnetic power generator uses the force between the polarity of the magnet and the induced magnetic field of the coil to generate suction and thrust forces, which are generated when a magnet enters and leaves the coil, respectively, and can reduce the motor power consumption to achieve an energy saving effect. From the viewpoint of single-phase magnetic power generators, an angle transformation arrangement is used to achieve a positive power output to maximize the power efficiency, and three-phase power generation is used to maximize the output, where 8 magnets and 12 six-wire wound coils are used in conjunction with a delta or Y connection to achieve three-phase output. Each phase is 120°out of phase and each phase has 4 coils that generate power per revolution simultaneously. The high output characteristic enables the use of the three-phase magnetic power generators in several industrial applications. Herein, for a single-phase power generator, 8 magnets and 10 wires were used in an angle transformation arrangement, which achieved an output efficiency of up to 129.7%, whereas the three-phase power generator with 8 magnets and 12 sixwire wound coils with a diameter of 0.4 mm were used in conjunction with a delta or Y connection and achieved, which achieved an output efficiency of up to 82%, indicating that both these generators can be used for emergency power generation in homes, factories, or hospitals.Microsystem Technologies https://doi.org/10.1007/s00542-019-04423-1( 0123456789().,-volV) (0123456789(). ,-volV)Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
