Title: Claw pole type generator
Inventor: KANEYUKI KAZUTOSHI
IPC: H02K3/493
Filed: 1994-03-17
Abstract: PURPOSE:To reduce an eddy current loss by mounting a magnetic anisotropic wedge which has high permeability in a radial direction of a rotor and low permeability in a circumferential direction in an opening of a slot opposed to the rotor. CONSTITUTION:When a magnetic anisotropic wedge 4 is mounted in an opening 2a of a slot 2 of a laminated core 1, a main magnetic flux M outputting from a claw pole 7a to the opening 2a side of the slot 2 reaches tees 1a of the core 1 at both sides of the wedge 4 through a high density part of the wedge 4. A main magnetic flux M returned from the core 1 to a claw pole 8a is similar. Accordingly, a magnetic flux density opposed to the opening 2a of the slot 2 is recovered until it sufficiently approaches a magnetic flux of the other part, and its varied width is reduced. Generally, since an eddy current loss is proportional to square of the varied width of the density, an eddy current loss of surfaces of the poles 7a, 8a is reduced in a claw pole type generator using the wedge 4.
