| 摘 要： | 针对汽车发动机冷却应用实现了一种无位置传感器控制的四相无刷直流风机系统。该四相无刷直流电动机的A、C两相和B、D两相绕组分别采用双线并绕方式,两相间的耦合系数为1,而任意其他两相之间的互感近似为零。基于该特点,控制系统采用半桥主电路结构可实现全桥电流的控制效果。与常规半桥无刷直流电动机系统相比,该电机系统可以实现较高的系统效率,同时也保持了低成本特点。为了进一步提高该风机系统的可靠性,采用基于软件实时采样反电势过零点的方法实现了无位置传感器控制,进一步简化了系统结构、提高了可靠性。最后,以90°电角度导通模式为例,给出了系统仿真和实验结果,验证了这一方案的可行性。

| Abstract: | A sensorless four-phase brushless DC fan for automotive engine cooling application was accomplished in the paper.The bifilar winding design is adopted in the motor,so that the mutual inductance between phase A and C or phase B and D is equal to their self inductance and the mutual inductance between any other two phases can be neglected.Based on the characteristic,full-wave current control is achieved through half-bridge structure.Compared with the general three-phase half-bridge brushless DC fan system,it ... |
