Abstract: A motor component covered with a novel electrocoating that fails to detrimentally affects magnetic memory medium provided in a hard disc or other is provided. With enhanced edge covering ratio, an improved insulation coating is easily formed on the motor component. An insulation coating is electrodeposited on an Nd—Fe—B system plastic magnet, a stacked core of silicon steel, a die-cast motor base of aluminum or other motor component through cationic electrodeposition. The electrodeposition paint for use includes 12 ppm or less of tin content in the aqueous solution, 0.5% or less by weight of carbon black content in the aqueous solution, and, instead, has titanium dioxide and/or silicon dioxide added to pigment. The electrodeposited insulation coating, which has a specified thickness, is heated to temperatures ranging between 40° C. and 90° C. After such preliminary curing, temperatures are again heated to between 150° C. and 190° C.

Abstract: An anisotropic plastics magnet having a maximum energy product (BH)max not lower than 0.9 MG Oe, a remanence Br not lower than 2000G and a coercive force Hc not lower than 1800 Oe, and being composed at least one of ferromagnetic powders having a large magnetic anisotropy constant and at least one selected from the group consisting of metal-cross-linked copolymers of .alpha.-olefin and .alpha.,.beta. unsaturated mono- or dicarboxylic acid and saponified copolymers of ethylene and vinyl acetate, the axis of the easy magnetization of said ferromagnetic powders being oriented substantially in one direction, and a process for producing the same comprising mixing the ferromagnetic powder and the resin and forming the mixture under heating while a magnetic field is being applied.
