【摘要】 提出一种无刷直流电机与行星齿轮减速器集成装置的设计概念。其基本思想是将外转子型无刷直流电机的转子与行星齿轮减速器的中心轮在结构上集成为一个一体化的部件,减少了联轴器,显著减小了轴向尺寸。介绍了该集成装置的结构原理,结合算例进行了齿轮设计,并应用 Ansoft／Maxwell软件进行了电机的电磁场分析。更多还原

【Abstract】 This paper presents a novel design by integrating brushless DC motor(BLDC) and planetary gear train(PGT). The basic idea is that the rotor of the outer rotor of the BLDC and the central gear of the PGT are integrated into an integrative component, shaft coupling is reduced and the axial dimension is decreased too. Working principle is introduced, the structural design of the gear is accomplished via a numerical example, analysis of the motor is accomplished via the software Ansoft/Maxwell.更多还原
