Claims

[Scope of utility model registration request]

A high-speed motor was installed in a motor room communicating with a vacuum chamber to which a vacuum evacuation means and an inert gas supply means were connected, and a plasma torch was placed opposite the material to be melted that was rotated by the high-speed motor. In the metal powder manufacturing apparatus, a dividing means is provided near the boundary between the motor chamber and the vacuum chamber, penetrating the outer frame of the high-speed motor and dividing the motor chamber and the vacuum chamber while maintaining airtightness of each;
A metal powder manufacturing apparatus characterized in that a vacuum evacuation means and an inert gas supply means are connected to the motor chamber, and a cooling section for circulating cooling water is formed on the outer wall of the motor chamber forming the motor chamber.
