摘要
提出一种新型的四相双转子平动式啮合电动机,该电动机的每个磁极由一个定子和内、外转子构成。4个磁极的内转子固连在一起构成一个4极内平动转子,外转子固连在一起构成一个4极外平动转子。控制磁极的工作顺序,可以驱动内、外平动转子在4个偏心轴约束下作方向相反且同步的公转运动,并带动两个内齿圈与外齿轮啮合输出低速大扭矩运动,该结构相互抵消了惯性力,增大了输出转矩。设计制作物理样机,运用有限元法分析在不同转子位置角的磁链特性。依据磁共能原理,计算电动机的静态转矩。通过样机试验获得电动机的转速、转矩特性。与传统的电动机和减速器组成的驱动装置相比较,双转子平动式啮合电动机具有起动快、效率高、输出转矩大的特点,是一种可行的平动电动机结构。
A novel four phase translational meshing motor with double rotors is presented,and each magnetic pole of new motor consists of one stator,one internal and external rotors.Four internal rotors of magnetic poles are fixed together as one four-pole internal translational rotor and four internal rotors are fixed together as one four-pole external translational rotor.If controlling electromagnetic force of magnetic poles,the internal and external translational rotors move opposite direction synchronously by circle translation with the restricting of eccentric shafts mechanism,meanwhile,it drive internal ring gears meshing with external gears to output big torque with the elimination of inertia force and the increases of output torque.The prototype is found,and the flux linkage characteristic is calculated through finite element method.In additional,the static torque is computed utilizing the magnetic coenergy principle.The characteristics of speed and torque are acquired form prototype experimental results.Compared with the driving device of traditional motor and reducer,the double rotors translational meshing motor is a feasible translational motor with features of rapid start,high efficiency and big output torque.
