PURPOSE:To strongly magnetize by laminating thin magnetic iron plates having recesses, to which 2P pieces of alnico magnets are inserted to hold the magnets, and inserting the magnets to a stator while a magnetizing coil is wound in the recess formed on the side disc. CONSTITUTION:Thin magnetic ion plates 20 having recesses 19' capable of containing 2P pieces of alnico magnets 19 are laminated in the prescried number and engaged with a rotational shaft 18. Side plates 23 (24) having recesses 21, 22 are contacted radially of the magnets 19 at both sides of the laminated core, a bolt 25 is passed via a through hole 25' formed previously, and integrally molded to form a rotor 26. Then, after magnetizing oil 27 is wound in the recesses 21, 22, the rotor 26 is inserted to the stator, not shown, the coil 27 is energized and magnetized, and is removed. In this manner, the magnets are magnetized in high permeance, thereby manufacturing a motor of high performance. |
