Hook shaped magnetic pole generator

Abstract

Abstract PURPOSE: To reduce magnetic flux leaked between magnetic poles with an adhesive containing hard magnetic material filled between the poles and a space formed by the pole and a field coil to fasten thereof. CONSTITUTION: A thermosetting adhesive 15 containing powdered ferrite or the like is filled into a space 13 between hook-shaped magnetic poles 4 forming a main magnetic circuit of leaked magnetic flux and a space 14 formed by the poles and a field coil 5 and olidified by heating. In the hard magnetic material power, magnetism is generated by flowing current through the field coil 5 in the opposite direction of the normal field current. With such an arrangement, the magnetic material is magnetized in the direction as indicated by H1 and H2. This works so as to offset the leaked magnetic fluxes ϕ1 and ϕ2 whereby the leakage thereof can be reduced. COPYRIGHT: (C)1979,JPO&Japio
