摘　　要：永磁式外转子变频调速三相同步电动机,它的主要特点有功率因数、系统效率均比异步电动机高,且起动转矩大、控制精度准确、设备整体安装空间紧凑。目前主流皮带输送机的驱动系统为采用异步电动机与减速器配合的方式,异步电动机和减速器的效率特别低,会导致驱动系统的损耗非常大。随着控制技术和永磁电机的发展,具有高效率的直驱方式受到科研机构的关注。所以,应用外转子变频调速三相永磁同步电动机直接驱动皮带机系统是十分有意义的。The variable-frequency adjustable-speed three-phase synchronous motor with permanent-magnet outer rotor has the main characteristics of higher power factor and system efficiency compared with induction motor,and has the advantages of large starting torque,accurate control precision and compact installation space of whole equipment.At present,the driving system of mainstream belt conveyor adopts the way of matching induction motor with reducer.If the efficiency of induction motor and reducer are particularly low,it will lead to large loss of the driving system.With the development of control technology and permanent-magnet motor,the direct drive mode with high efficiency has attracted the attention of scientific research institutions.Therefore,it has a great significance of applying variable-frequency adjustable-speed three-phase PMSM with outer rotor to drive the belt drive system directly.
