  • Patent number: 4648004
    Abstract: Disclosed are a method of detecting a magnetic preorientation in mechanical parts, such as motor rotors, and a device, utilizing this method, for the magnetization of tubular parts. The device includes a magnetization winding to accommodate the tubular part and an associated magnetizing apparatus. According to the invention, the part (100) is first magnetized near the surface by means of a recording head (300) in such a manner that discrete bar magnets (121 to 132) are formed on the surface between the preoriented zones in the circumferential direction, their lines of flux running between their poles in the preferred direction of the preoriented material, There originate in the preoriented pole zones outside stray fields of twice the number of poles used to position the part (100) during magnetization.
