Linear motor for sliding door
View Patent ↗The invention relates to a linear motor for a sliding door, comprising a mover assembly, a stator assembly and a controller for controlling the mover assembly to move, the stator assembly is electrically connected with the controller, and comprises two or more stators; the controller is arranged between the two adjacent stators; and end parts of the stators on two sides of the controller are provided with Hall devices. The mover assembly can move on a left side and a right side of the controller, and the moving range is increased. Furthermore, the Hall devices are arranged at the end parts of the stators on the two sides of the controller, the moving range of the mover assembly to the left side and the right side can be further increased, so that the system can adapt to a wider door opening without changing the length of the stator assembly.
