Abstract
The present disclosure discloses a linear motor module, including a mounting base, a magnet mounting seat arranged on the mounting base, three stators arranged on the magnet mounting seat and composed of array-structured permanent magnet assemblies, linear guide rails arranged on the mounting seat, sliding blocks mounted on the linear guide rails, a moving plate arranged on the sliding blocks, and three inductors arranged on the moving plate and corresponding to the stators. The magnet mounting seat has three mounting surfaces; the three stators are separately located on the three mounting surfaces; the three inductors are arranged in a one-to-one correspondence to the three stators; and an angle between two adjacent stators is 60 degrees. The linear motor module of the present disclosure is reasonable in structural design. The angle between two adjacent stators is 60 degrees, so that a normal attracting force between the stator and the inductor on each surface can be compensated for each other, and a vector sum of the normal attracting forces tends to be zero. Therefore, the normal attracting force caused therefrom and a load and friction loss on the linear guide rails can all be …
