PURPOSE:To form a cylindrical resin magnet which is light weight and has sufficient performance by fixing with a support part which has a structure able to fix a plate type resin magnet the both ends of which are fixed on a shaft. CONSTITUTION:Plate type resin magnets 1-4 are fixed with support parts 6, 7 fixed near the both ends of a shaft 5. If the plate type resin magnet is larger and fixing at both the ends is not sufficient, the support parts may be increased for fixing. For this reason, the magnet can be used as same as a conventional cylindrical multipolar magnet in spite of extremely light weight and the accuracy of the dimensions is remarkably better than that of conventional ones. |
