Providing a shape of the magnet to suppress the magnetic resistance generated during the generator operation to a minimum

摘要

PROBLEM TO BE SOLVED: To provide a shape of a magnet which makes it possible to minimize the magnetic force resistance occurring to prevent its rotation as a rotor magnet passes through the lateral position of the stator coil conductor around the rotor magnet, for rotation.;SOLUTION: By making the magnetic poles of a rotor magnet in the generator into a shape like a head of an English letter, "Y" by bending the upper part of the magnetic pole tip and the lower part of both side arm parts as seen in the direction of rotation so that curvature matches as much as possible with the lines of magnetic force generated around the stator coil located outside the magnetic pole tip, magnetic force resistance received from magnetic lines of force generated in the stator coil when the rotor magnet rotates is minimized, so that it is possible to rotate the rotor magnet with a smaller force.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
