无刷直流电机的特点是体积极小、而且质量也比较轻、工作的效率很高,除此之外在损耗方面也比较小等,这些都是无刷直流电机的典型特征,关于无刷直流电机的应用十分广泛,除了用于航空航天以及机械自动化等领域之外,还在汽车行业中也运用很普遍,另外无刷直流电机还涉及到了空调以及电动车和冰箱等电器方面。但是,考虑到电机自身在换向方面存在着一定的问题,所以从而引起了通过采用传统的控制方法是很难摆脱由于电磁转矩以及电流脉动过大的情况,而且在精度的控制方面不是很精确,这些存在的问题使得无刷直流电机在一定程度上受到了约束的作用,从而应用的范围也会因此受到相应的影响。所以,对无刷直流电机方面进行相关的研究是很有必要的。
Brushless DC motor is characterized by very small size, but also the quality is relatively light, high efficiency of work, in addition to the loss is relatively small, etc. These are typical characteristics of brushless DC motors, brushless DC Motor is widely used, in addition to the fields of aerospace and mechanical automation, but also in the automotive industry is also very common, in addition to brushless DC motor also involves the air conditioning and electric cars and refrigerators and other electrical aspects. However, considering that the motor itself has some problems with the commutation, it is difficult to get rid of the excessive electromagnetic torque and current pulsation by adopting the conventional control method, and it is not very precise in terms of control Precisely, these existing problems make the brushless DC motor to a certain extent by the role of constraints, so the scope of application will therefore be affected accordingly. Therefore, the relevant research on brushless DC motor is necessary.
