Title: Permanent magnet rotor
Inventor: YASUHARA TAKASHI
IPC: H02K1/27
Filed: 1994-09-16
Abstract: PURPOSE: To reduce the loss caused by eddy currents so as to facilitate the manufacture with high efficiency by forming a thin cylinder of nonmagnetic material which surrounds, with a fixed thickness, a permanent magnet by impregnating it with a nonmagnetic material large in mechanical strength, and sintering it. CONSTITUTION: In the sintering process of a compressed molded item such as an iron oxide, etc., the pores 12a made numerously in the surface of the periphery of a permanent magnet 12 are filled with copper. In the heating process at the time of sintering, copper gets in liquid phase and diffuses in iron oxide, but when the quantity of copper reaches a fixed value, the diffusion stops, and the copper left superfluously remains in skeleton as liquid phase, thus it becomes liquid phase-solid phase coexistent alloy, and it expedites the sintering at low temperature. In this process, copper surrounds, with a fixed thickness, the periphery of the permanent magnet 12 in the shape of a cylinder 12b. The sintered thin cylinder 12b of copper becomes a member for protecting the permanent magnet 12 firmly, as a kind of alloy.  Because the magnetic flux of the permanent magnet 12 passes the thin cylinder 12b at a right angle, an eddy current is generated in the thin cylinder 12b, but the electric resistance of copper is small, so the eddy current loss is reduced.
