摘要：
For meeting the functional requirements of the multi-DOF drive unit for omnidirectional vehicle wheels and multi-orientation camera for smart car, and remedying the defects of structural complexities, control difficulties and poor dynamic performance caused by integrating multiple conventional motors to achieve multi-DOF drive, a multi-DOF spherical induction motor is proposed based on the theory of linear induction motor. The spherical induction motor is composed of three blocks of stator with arc surface and a spherical hollow rotor, and can realize two-DOF drive. Differing from the traditional motor, which output the torque through its shaft, the spherical induction motor directly output its torque from motor's surface due to the unique structure of stator. Firstly, the dimensional parameters of the multi-DOF spherical induction motor are designed in this paper. Then its model is built with ANSYS Maxwell software and a transient electromagnetic simulation is conducted. Meanwhile, a parametric analysis is performed on the spherical induction motor to acquire its characteristic curves at different voltages and frequencies and to reveal the mechanism of torque and rotation speed control for the motor. The results show that the torque and power of the multi-DOF spherical induction motor increase with the rise of voltage, while with the increase of frequency its torque and power fall and the range of rotational speed widens. The performances of the spherical induction motor designed meets the requirements preset. © 2019, Society of Automotive Engineers of China. All right reserved.
