Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, and particularly relates to a cooling structure for a linear motor mover. Background Art

[0002] The motion principle of a linear motor mover is based on the fact that a magnetic field acts between a coil and a magnet to generate linear motion. When an electric current flows through the coil, an electromagnetic force is generated, causing reaction forces to be generated at both ends, thereby controlling the position and speed. This design enables the linear motor to directly convert electrical energy into mechanical energy of linear motion without any intermediate transmission conversion device.
