Patent ID: 8354763

Claim:
A magnet generator comprising: a flywheel which is a bowl-shaped rotor; a plurality of magnets which are installed on an inner peripheral surface of a cylindrical part of the flywheel; and a stator which includes a laminated core and a winding coil wound around the laminated core installed to be opposed to the magnets inside the flywheel to generate power by an electromagnetic induction between the winding coil and the magnet, wherein a temperature increase suppressing component is disposed in the stator to suppress heat generation of the laminated core and the winding coil, wherein, as the temperature increase suppressing component, a heat dissipation enhancing member which has no relation with a magnetic circuit is fitted into a space formed by cutting a bulk of the laminated core used for configuring the magnetic circuit, and a cooling tube installed to be inserted into or penetrate the heat dissipation enhancing member are provided, heat dissipation performance of the stator is enhanced by the heat dissipation enhancing member, and cooling performance of the stator is enhanced by supplying a cooling medium to the cooling tube.
