Design and Research of a PMLSM-Driven Elevator Door Machine
Most of the existing elevator door driven by rotary motors, this paper used to design the permanent magnet linear synchronous motor as the Drive Fixed Motor, the door can eliminate the need of drive mechanism between the motor and the door, direct drive door in a straight line, improve reliability and security of the door machine. Through experimental analysis, the design uses DSP and Intelligent Power Module (IPM) combination of control system for elevator door operation by setting curve and stable operation.
