Title:
MAGNETIC POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/157049
Kind Code:
A1
Abstract:
A magnetic power generator (1) is provided with a stator and a rotor. The stator includes a plurality of salient poles (14), the salient pole being made up of a magnetic path section (15) and a protrusion section (16). A coil is wound around the magnetic path section, and the protrusion section protrudes toward both sides of a front end of the magnetic path section. A plurality of permanent magnets (6) is attached to the rotor so as to face the salient poles (14). The salient poles (14) having the same phase are adjacently disposed in the circumferential direction, and a coil having the same phase is wound in series around the adjacently disposed salient poles (14) having the same phase. A front end section (17) is made up of the front end part of the magnetic path section (15) and the protrusion section (16), and the disposition angle (θ2) between the front end sections (17) having the same phase is equal to or less than the pole arc angle (θp) of the permanent magnet (6), and is greater than the disposition angle of the adjacent front end sections (17) having different phases. The magnetic path section (15) in the salient pole (14) adjacent to the salient pole (14) having a different pole is disposed on the same phase side of the center line of the front end section (17) of the salient pole (14) adjacent to the salient pole (14) having a different pole.
