Abstract

In order to create an efficient electric power generator that suppresses cogging, reduces leakage of magnetic flux density, and regulates magnetic flux density orientation, an electricity generating coil with a ferromagnetic body core is used. A magnetic body core is sandwiched between the first magnetic bodies. First magnets are fixed to both sides of the electricity-generating coil by second magnetic bodies and first non-magnetic body spacers. This ensures a fixed space between the first magnets and the first magnetic bodies. On one side of the second magnetic body, a pair of first magnets is fixed to both ends. When a rotating portion is rotated, the opposing first magnets and the electricity generating coil are aligned on a straight line, and the magnetic flux density orientation lies in one direction through the second magnetic body, including the opposing first magnets.

Dependent claims

A generator, comprising:

a base;
a pair of first magnetic bodies fixed to the base;
a rotation shaft rotationally fixed to the pair of first magnetic bodies;
an even number of power generation coils having power generation coil cores sandwiched at equal intervals on the same circumference around the rotation shaft by the pair of first magnetic bodies to be in contact with and fixed by the pair of first magnetic bodies;
on a side of each of the pair of first magnetic bodies opposite to the even number of power generation coils:
first non-magnetic body spacers each fixed to the rotation shaft while maintaining a constant space from each of the pair of first magnetic bodies;
and
second magnetic bodies fixed to each of the first non-magnetic body spacers;
and
at both ends of each of the second magnetic bodies on one side on a side of the even number of power generation coils:
first magnets fixed at a position facing each of the even number of power generation coils being interposed therebetween, on the same circumference, at the same intervals, as the power generation coil around the rotation shaft, while maintaining a constant space from the first magnetic body,
wherein:
the first magnetic body is arranged between the power generation coil and the first magnets,
the first magnets are arranged at both ends of the second magnetic body, and
when the first magnets facing each other are aligned on a single straight line with the power generation coil due to a rotational movement, the first magnets including the first magnets facing each other are arranged so that a direction of magnetic flux density is unidirectional through the second magnetic bodies.
