Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of linear motor modules, in particular to a novel linear motor module. Background Art
[0002] A linear motor is also called a linear motor. As the name suggests, it is a motor that can produce linear motion. A linear motor converts electrical energy into mechanical energy for linear motion and does not require any intermediate transmission conversion device. Therefore, it is more efficient than a rotary motor that generates linear motion through a conversion device.
[0003] The utility model with the existing authorization announcement number CN219627552U discloses a linear motor, which includes a stator structure and a mover structure that reciprocates above the stator structure. The mover structure includes an enclosure, a mover, a reader and at least one pair of sliders. The mover, the reader and the sliders are distributed inside the enclosure.
[0004] By adopting the above technical solution, the embodiment of the present application solves the problems of inconvenient motor assembly, long assembly time, and inconvenient maintenance. However, with the above technical solution, when the linear motor is running at high speed, the stator and the mover are installed too close, resulting in a sense of jerkiness when the motor moves. In addition, the close distance is not conducive to heat dissipation and cooling. If the temperature cannot be lowered, long-term use will seriously affect the service life of the machine. This is also the same problem that exists in linear motors on the market and needs to be improved. Utility Model Content
