PURPOSE:To cool a stator coil satisfactorily, and to prevent overheating exactly, by forming an air-gap cooling between the stator coil and a wall of a brazing material storage tank. CONSTITUTION:Each stator coil 117..., a magnetic field which passes through a stator core 115 and an iron core 119, and crosses a brazing material pressure passage 110 is formed. Between the stator coils 117... of a coil mechanism 114, and an outside bottom wall plate 107, air-gaps for cooling 118... are provided. Accordingly, the stator coils 117... are cooled satisfactorily, and overheating of the stator coils 117... due to heat transmitted from a brazing material storage tank 101, and heating of the stator coil itself is prevented effectively. |
