Process equipment and method for solidification and molding of magnetic pole protective coating

Abstract

A process device and method for curing and forming a magnetic pole protective coating. The process device comprises a first energy transfer system and a second energy transfer system. The first energy transfer system comprises: a first limiting support part (100) facing a first surface of a magnetic yoke (41) and spaced from a magnetic pole (43) at a predetermined distance to form a first accommodating space; a first elastic cavity part (200) which is a flexible sealed cavity, provided on the first limiting support part (100), and located in the first accommodating space; and a first fluid medium supply system (600) communicated with the first elastic cavity part (200) and used for supplying a pressurized fluid medium to the first elastic cavity part (200) or pressurizing and heating the fluid medium. The target of consistent temperature rising control and uniform temperature distribution of magnetic pole protection formation quality is achieved, so that the stress in a magnetic pole protection coating during its formation process is eliminated, the formation quality is ensured, and the risks of stripping and breakage caused by the stress during a subsequent application process are reduced.
