Abstract

Electric motors are used globally, especially in industrial applications, and achieving high energy efficiency is a major problem. Variable transmissions are effective in reducing the energy consumption of motors, but practical variable transmissions are bulky and heavy, making them unsuitable for robots. To overcome this problem, two motor-driven mechanisms have been proposed. The two motors are operated independently and assigned to the high-speed drive and high-torque drive, and one motor always becomes dead weight. Therefore, we propose a coupled-driven switchable transmission system that can switch the high-speed and high-torque drives by combining the rotation directions and utilizing the output of both motors. The developed device uses two 22-W motors and can switch the reduction ratio from 1/15 to 1/375. The maximum torque, maximum rotation speed, and weight are 10 Nm, 500 rpm, and 905 g, respectively. The experimental results show that the relative speeds of two motors are significant for the coupled drive; nevertheless, this device can be controlled by conventional voltage control without precise speed control.
大传动比耦合驱动高速高扭矩可切换变速器
全球都在使用电机,尤其是在工业应用中,实现高能效是一个主要问题。可变传动装置能有效降低电机的能耗,但实用的可变传动装置体积大、重量重,不适合机器人使用。为了克服这一问题,我们提出了两个电机驱动机构。两台电机独立运行,分别分配给高速驱动和高扭矩驱动,其中一台电机总是成为自重。因此,我们提出了一种耦合驱动的可切换传动系统,该系统可通过组合旋转方向和利用两个电机的输出来切换高速驱动和高扭矩驱动。所开发的装置使用两个 22 瓦电机,可在 1/15 到 1/375 之间切换减速比。最大扭矩、最高转速和重量分别为 10 牛米、500 转/分和 905 克。实验结果表明,两台电机的相对速度对耦合驱动非常重要;不过,该装置可以通过传统的电压控制进行控制,而无需精确的速度控制。
