摘要： It is desired to design a coreless motor in which a gap size is set to be as small as possible, and a magnet having a large energy product is used in order to increase the gap magnetic flux density since the coreless motor has no iron core so that the magnetic flux density is small in the gap part. A rotor core of the motor has a permanent magnet rotor which is formed by a compression molding means, and which is formed of a compact formed by molding a powder material, the compact comprising a bond magnetic portion mainly composed of a binder and a magnetic powder, and a soft magnetic portion mainly composed of a binder and a soft magnetic powder, the bond magnetic portion having magnetic poles having at least one surface which is mechanically bonded to the soft magnetic portion, in order to solve the inherent problems.

摘要： A conventional method for forming an insulating film on a magnet has a difficulty in achieving sufficient improvement in magnetic characteristics due to nonuniformity of a coating film, and an extended time and higher temperature which are required in a thermal treatment. In order to solve the problems, the present invention provides a treating solution composed of an alcohol based solvent and a rare earth fluoride or alkaline earth metal fluoride dispersing in the solvent. In the treating solution, at least one X-ray diffraction peak has a half-value width larger than 1°. The present invention also provides a method for forming an insulating film using the treating solution.
