Title:
LINEAR MOTOR FOR SLIDING DOOR
Document Type and Number:
WIPO Patent Application WO/2019/080683
Kind Code:
A1
Abstract:
The invention relates to a linear motor for a sliding door. The linear motor comprises a mover assembly, a stator assembly and a controller for controlling the movement of the mover assembly. The stator assembly is electrically connected with the controller; the stator assembly comprises two or more than two stators; the controller is arranged between the adjacent two stators; and ends of the stators on the two sides of the controller are provided with Hall devices. The controller is arranged between the adjacent two stators, so that the mover assembly can move on both the left side and the right side of the controller, which increases the moving travel of the mover assembly. Further, the ends of the stators on the two sides of the controller are provided with the Hall devices, so that the travel of moving to the left side and the right side of the mover assembly is further increased; thus, even the length of the stator assemly stays the same, the linear motor system can adapt to wider door openings and the adaptability of the system is greatly improved.
