摘要:
为了提高系统可靠性,将余度技术引入到永磁无刷直流电机设计中。设计了2种定子绕组方式,包括同槽嵌放和隔槽嵌放结构。建立了2种结构下的数学模型,对绕组电感进行了分析计算,推导了绕组自感和互感之间的关系。根据数学模型,设计了双余度永磁无刷直流电机的具体结构参数,对转速和转矩进行了仿真。利用magtrol测试系统对双余度永磁无刷直流电机进行了实验,对比分析了2种结构不同工作模式下的机械特性曲线。实验结果表明:2种结构的双余度无刷直流电机在运行过程中,具有良好的动态特性,2套绕组同时工作时其转矩为1套绕组工作时的2倍;2套绕组并未对电机性能产生不良影响,但大大提高了系统可靠性。

Abstract:
In order to improve the reliability of the system, the redundancy technology is introduced into the designof permanent magnet BLDCM.Sections 1 through 3 of the full paper explain our design, computer simulation andexperimental research; we believe that our design is effective.The core of section 1 consists of: (1) two kinds ofstator structure are designed, including one slot and two slots; (2) the mathematical model of the motor is set up;the winding inductance is analyzed and calculated, and the relationship between the winding inductance and mutualinductance is deduced.The core of section 2 is that, according to the mathematical model, the parameters of themotor are designed and the rotational speed and torque are simulated.The core of section 3 consists of: (1) themotor is tested on the MAGTROL testing system; (2) the mechanical characteristic curves of both kinds of statorstructure under different working modes are compared.The simulation results are given in Figs.3 through 6 and theexperimental results are given in Figs.7 through 12.Both the simulation and the experiment results show that: (1)the motor of each kind can achieve good dynamic characteristics and the torque is increased by 100% with two setsof windings; (2) two sets of winding did not affect motor performance, but it did indeed greatly improve the systemreliability.
