As a drying method in such a vacuum drying furnace, for example, a heater panel is heated by electricity, steam, etc. arranged in the vacuum drying furnace, and air is blown from a blower tube (air, etc.) to generate hot air for maintenance. After contact with the motor after washing, etc., heat it. This heating temperature is for heating to a vacuum evaporation temperature. For example, when the surface temperature of the electric motor reaches 40 to 60 ° C., the inside of the furnace is evacuated to a vacuum degree of about 5 tr to lower the boiling point to adhere to the cleaning. The water content can be evaporated and dried quickly and reliably, and if the degree of vacuum is further lowered, the surface temperature of the electric motor can be evaporated and dried at a low temperature. Also, after the washing, for example, when the varnish applied to the insulating material is dried as an insulating treatment, the varnish can be dried in the same manner, and when the temperature of the electric motor reaches about 60 ° C after the drying, the air is blown by the heater. By stopping the heating, switching to normal temperature air blowing and cooling with air blowing, it is possible to cool more rapidly. In such blast heating into the furnace, the temperature difference between the upper and lower positions of the electric motor can be kept within 5 ° C by convection of the hot air flow in the furnace, preventing thermal deterioration of the electric motor insulation and improving the quality. It is possible to dry while surely preventing the deterioration. Further, as described above, when drying after the insulation treatment, a part of the varnish melts and drip due to heating, so it is preferable to provide a molten drip liquid receiving pan immediately below the carriage to prevent scattering into the furnace, for example, multiple layers By arranging in a zigzag pattern in the width direction of the furnace, it is possible to reliably receive the dripping liquid without obstructing convection air flow.
