current also significantly increased.Figure 6 displacements and the current curveFigure 7 qaxis coercion to force and nonVI. CONCLUSIONThrough the analysis of the experimental,using the permanent magnet synchronous linear motor as drive motor, realized the elevator door to run the operation curve by default, and the door system is reliable,low system can also be used to Warehouse door and Home automatic door, but also can use the system to reform the existing elevator door and automatic door.REFERENCES[1] Ke Wang, Liming Shi, Yaohua Li and Jinwei He.
