Liquid-cooled casing, magnetic suspension motor, and magnetic suspension apparatus

Abstract

The present invention relates to a liquid-cooled casing, a magnetic suspension motor, and a magnetic suspension apparatus. The liquid-cooled casing includes a casing body and a base. The casing body includes an annular shell, a central cylinder, and a first bottom plate, wherein the annular shell, the central cylinder, and the first bottom plate jointly define an annular space. The base includes a second bottom plate and a central post. A first liquid cooling chamber is formed inside the annular shell. One end of the central cylinder is an open end, and the other end is a closed end. The edge of the second bottom plate is hermetically and fixedly connected to one end of the annular shell. The central post extends through the central cylinder, and a second liquid cooling chamber is formed between the outer wall of the central post and the inner wall of the central cylinder. The second bottom plate is provided with a first flow port and a second flow port spaced apart from each other. The first flow port communicates a portion of the first liquid cooling chamber with a portion of the second liquid cooling chamber, while the second flow port communicates another portion of the first liquid cooling chamber with another portion of the second liquid cooling chamber.
