Abstract

A distributed electromagnetic twin-motor for duplex machining of disk-like workpieces is presented. Featured with independent current inputs in the EMs, this motor can ensure minimum bearing reaction during cutting process by simultaneously compensating for the external loadings with the electromagnetic forces while spinning the rotor. With closed-form representations of the current-force model, the desired current inputs can be computed from the force vector determined by the control method for minimum bearing reaction. Simulation is performed for given cutting forces as external loading and the results show that the control method of the twin-motor can adjust the actuating force and torque to cancel the imbalance loading conditions.
双相加工用最小轴承反力双电机的分析研制
提出了一种用于盘状工件双工加工的分布式电磁双电机。该电机具有独立的电流输入,在旋转转子的同时,通过电磁力同时补偿外部负载,可以确保切割过程中最小的轴承反作用力。通过电流-力模型的封闭形式表示,可以从最小轴承反力控制方法确定的力向量中计算出所需的电流输入。以给定的切削力作为外加载进行了仿真,结果表明,双电机控制方法可以通过调节作动力和转矩来消除负载不平衡的情况。
