Problems solved by technology

[0003] Compared with the traditional rotating motor, the magnetic circuit of the linear motor is open, and there is no mechanical transmission buffer between the load and the linear motor. The control of linear motors brings great challenges. On the other hand, a little carelessness in the process of debugging and operation can easily lead to the danger of speeding, resulting in personal and property losses.
