温湿交变工况下RGV主驱电机高可靠宽域稳定运行优化设计
Optimization design for highly reliable,wide-range stable operation of an RGV main drive motor under alternating temperature and humidity conditions
摘要
Abstract
[Background]In intelligent logistics systems for the tobacco industry,the main drive motor of a rail-guided vehicle(RGV)is prone to condensation corrosion,high magnetic leakage loss,and unstable energy efficiency under multiple operating conditions when operating in alternating temperature and humidity environments and in coordination with three-dimensional conveying systems.[Methods]Taking the centralized distribution system for multi-specification materials in tobacco packaging workshops as the application scenario,this study analyzes the dynamic load characteristics of the main drive motor during cross-layer conveying.With adaptation to temperature and humidity conditions as the focus,a double-sleeve split-core main drive motor is designed.Based on a finite element model and the magnetic flux density integration method,the effects of shielding sleeve material(SUS316,SUS430,and zirconia)and thickness on the motor leakage coefficient are analyzed,and an optimized composite shielding sleeve scheme is proposed.Loss calculation and simulation analysis are then used to evaluate the power factor platform characteristics of motors with different shielding sleeve materials,and prototype experiments are conducted to verify the effectiveness of the design.[Results]The designed double-sleeve main drive motor effectively isolates the motor from temperature-and humidity-induced erosion;the SUS430 shielding sleeve effectively suppresses magnetic leakage(the leakage coefficient decreases from 1.32 to 1.19 as the thickness increases from 0.3 to 0.7 mm),while the zirconia shielding sleeve significantly reduces eddy-current loss.The optimized SUS430/zirconia composite shielding sleeve achieves a stable leakage coefficient of 1.25,with the increase in magnetic leakage controlled within 11.6%.The motor with the SUS430 shielding sleeve reaches a power factor platform of 0.96 in the 80%～100%load range,representing a 10.5%improvement compared with a traditional shielded permanent magnet motor.[Conclusion]The designed RGV main drive motor and optimization scheme can effectively address motor reliability,magnetic leakage,and low power factor under temperature and humidity conditions,providing theoretical support and an engineering solution for upgrading and optimizing RGV main drive systems in the tobacco industry and similar complex environments.关键词
