直线感应电动机在RGV穿梭车上的应用研究

Applied Research of Linear Induction Motor to RGV Shuttle

随着自动化物流系统输送效率的提升，RGV穿梭车的走行速度较低和加减速控制较慢的问题已逐渐成为发展的瓶颈。直线感应电动机因其同步速度高、直接推力大等特点，成为了RGV穿梭车驱动方式改进的关注方向。本文通过直线感应电动机在RGV穿梭车上应用的论证，并对试验样机进行了测试与分析，探讨了技术的可行性。对应用中出现的直线感应电机边端效应、气隙影响、温升等对穿梭车控制可能产生影响的相关问题提出了看法和应对措施，从而为发展直线感应电动机在RGV穿梭车上的应用提供了借鉴和依据。

With the improvement of transport efficiency of automation logistics system, the problems of lower moving speed and slower accelerating/decelerating control of Rail Guided Vehicle （RGV） shuttle have gradually become a development bottleneck. Due to its characteristies of high synchronous speed, large direct pushing force, Linear Induction Motor （ELM） has been considered as a concerned direction of improving drive mode of RGV shuttle. By ,neans of the argumentation on the application of LIM to the RGV shuttle, and the test and analysis for the experimental prototype, the technical feasibility is discussed in this paper. Furthermnre, the opinions aud solutions are proposed for the related problems of LIM＇s end effect, air- gap influence, temperature rise, ere, which have been fonnd in the application and may ＇affect the shuttle＇s control, thus the reference and reason for developing application uf LIM to RGV shuttle.
