PURPOSE:To enhance the efficiency and to reduce the noise by filling semicurable magnetic material into the hole of the slot of a stator core, flowing a high frequency current through the coil in the slot before the material is cured, and concentrating the fine magnetic powder at the inner peripheral side of the core. CONSTITUTION:A filling cylinder 21 is inserted into a stator core 3 on which a coil 6 is wound in a slit 5 by opening a small gap 24. Then, fluid semimagnetic material is filled under high pressure from the filling hole 22 of the cylinder 21. Then, before the magnetic material is cured, a high frequency current is flowed to the coil 6 wound in the slot 5, the fine powder in the material is concentrated at the inner peripheral side of the core 3 and dried and cured. |
