Technical Field
[0001] This utility model relates to the field of linear motor technology, and in particular to a moving stator structure for a permanent magnet synchronous linear motor. Background Technology
[0002] A linear motor is a device that directly converts electrical energy into linear motion mechanical energy. With the development of industry, linear motors are used in machine tools and other equipment. Linear motors are transmission devices that do not require any intermediate conversion mechanisms and can be used in any application that requires linear drive.
[0003] Traditional permanent magnet synchronous linear motors typically design the mover and stator as a tightly integrated whole. When the mover fails or needs to be replaced according to different working requirements, the disassembly process is extremely cumbersome due to its tight integration with the stator. It requires professional technicians to use various tools and go through multiple steps to remove the mover. This process not only consumes a lot of time, but also requires high operating skills and experience from the technicians, which leads to a significant decrease in maintenance efficiency.
[0004] Therefore, it is necessary to provide a permanent magnet synchronous linear motor moving stator structure to solve the above-mentioned technical problems. Utility Model Content
