直线电机驱动的电梯门机及其Psoc控制

Psoc Control of a LIM-Driven Elevator Door

传统的电梯门采用直流或是交流旋转电机驱动。文章介绍了一种采用直线电机的新型驱动方式,并结合直线电机的特点,采用特殊的恒压调频控制手段,运用Psoc单片机驱动IPM实现控制电梯门的开/关运行曲线。

Elevator slider door is usually driven with a DC or AC rotary motor through same complex mechanism. In this paper, a novel LIM - driven elevator door system is presented, in which a Psoc controls an IPM to drive the door following a pre -defined opening/closing profile. A special constant voltage variable frequency （CVVF） strategy is applied to reduce the acoustic noise.
