Description

Technical Field

[0001] This utility model relates to the field of long stator core manufacturing, specifically to a long stator vacuum epoxy casting mold. Background Technology

[0002] In maglev trains, the long stator linear motor is a core component. The long stator core is the heart of the long stator linear motor, providing the most robust guarantee for the maglev train's levitation, traction, and braking functions. Since the operating environment is outdoors, the epoxy encapsulation of the long stator linear motor is particularly important, directly affecting many key factors such as corrosion resistance, aging resistance, crack resistance, and UV resistance, thus impacting the entire maglev train's lifespan and safety. In existing technologies, the relative position of the core within the mold cavity needs to be manually adjusted, resulting in significant positional errors. Inaccurate core positioning affects the distribution of magnetic lines of force in the linear motor, leading to a low yield rate. Utility Model Content
