| 中文摘要 |
| 文章主要研究一种新型盘式结构, 单定子、双转子对转永磁同步电机的直接转矩控制方法. 首先, 分析并建 立了双转子对转电机的数学模型; 其次, 在一个逆变器不能同时直接控制两边转矩的情况下, 根据两边转子位置差 和电磁转矩与转矩角的关系, 分时控制电机转矩波动较大一边转矩, 来保证电机在不平衡负载时两边转子同步; 最 后, 通过试验控制一台额定转速500 r/min, 额定功率1.2kW的盘式对转电机, 验证了方法的可行性, 并且电机运行稳 定可靠. |
| 英文摘要 |
| We investigate the torque control method for a new motor which is of disc structure, with one stator but two permanent magnet rotors located in the left and right sides of the stator. Firstly, the mathematic model of the permanent magnet synchronous motor (PMSM) with contra-rotating rotors is developed. Secondly, when a single inverter can not used to control the torques on both sides simultaneously, the control is applied only to the side with more significant torque ripples, with the control time determined by the positions of two rotors and the relationship between the electromagnetic torque and torque angle. In this way, we achieve the time-sharing control of torques. This method is tested on a disc contrarotating PMSM with 1.2kW power rating and 500 r/min speed rating. Experimental results show a desirable performance of this control approach, and the controlled system runs stably and reliably. |
