In this paper, the use of conical induction machines is proposed for an in-wheel traction application. Such machines offer a rotational movement combined with a translational motion of the rotor. The horizontal movement is essential when active engagement and disengagement of the motor from the wheel without any extra mechanical component is required. This paper first investigates the basic concepts of how the conical machine functions and then proposes a mission strategy for a relevant traction application. A detailed description of the full scheme is given. In order to achieve the required performance, an innovative control method for both degrees of freedom of the machine (i.e., torque production and axial movement) is proposed and validated against a small-scale demonstrator of the whole system.

用于车轮牵引应用的二自由度系统


在本文中，建议将锥形感应电机用于轮内牵引应用。这种机器提供与转子的平移运动相结合的旋转运动。当需要电机与车轮的主动啮合和脱离且无需任何额外的机械部件时，水平运动至关重要。本文首先研究了锥形机器如何工作的基本概念，然后提出了相关牵引应用的任务策略。给出了完整方案的详细描述。为了实现所需的性能，提出了一种针对机器自由度（即扭矩产生和轴向运动）的创新控制方法，并针对整个系统的小规模演示器进行了验证。
