Title:
TOOLING FOR CURING MOLDING OF MAGNETIC POLE PROTECTIVE COATING
Document Type and Number:
WIPO Patent Application WO/2019/148787
Kind Code:
A1
Abstract:
Provided is a tooling for curing molding of a magnetic pole protective coating of an electric motor rotor (40). The tooling comprises a first energy transfer system, with an electric motor rotor (40) being horizontally disposed in an axial direction. The first energy transfer system comprises: a first limiting support component (100) spaced apart from a magnetic pole (43) by a predetermined distance to form a first accommodation space; a first elastic cavity component (200) located in the first accommodation space; and a first fluid medium supply system (600) in communication with the first elastic cavity component (200) for supplying a pressurized fluid medium or a pressurized heating fluid medium to the first elastic cavity component (200). This tooling ensures that the driving force of a binder permeates in a circumferential direction, an axial direction and a radial direction in a protective coating molding space, thereby fully filling the gaps in a protective system. Moreover, during the magnetic pole protection molding, both uniform control of the quality and the rise in the temperature and the uniform distribution of temperature are achieved, thereby ensuring the molding quality in order to reduce the risk of the protective coating peeling and breaking.
