PURPOSE:To eliminate damage to a bearing without eccentricity and to contrive the improvement of productivity with good accuracy by coinciding the magnetic center of a stator core with the geometrical center of a flange by utilizing the rings of a magnetic substance arranged in an assembling device. CONSTITUTION:The rings 8 of a magnetic substance having almost same inside and outside diameters as a stator core 1 are fixed on the base 14 of an assembling device. Furthermore, a cylinder 9 is fixed by meeting geometrical center with the rings 8. The surfaces of the rings 8 are freely moved by arranging nonmagnetic steel balls 11, for example. A stator core 1 mounted with a coil is inserted in the assembling device to supply current to the coil and a flange 3 is inserted from the upside of the coil along the inner surface of the cylinder 9 after agreeing with the magnetic center by making the iron core 1 coincide with the rings 8. The stator core 1 and the flange 3 are in concentric status under this condition. Therefore, the stator core 1 is fixed by a bolt 7. |
