开关磁阻电动机开关磁阻电动机switched reluctance motor步进电动机)不同的是，开关磁阻电动机必须有位皿传感器，以保证定子绕组通电状态与转子位里间有严格的同步关系。结构与原理开关磁阻电动机是一种定、转子均为凸极结构的磁阻电动机，它的典型结构如图1所示。它的转子上既无绕组也无永磁体，定子磁极上放置集中线圈，径向相对的两个磁极上的线圈申联构成一相绕组，并使两个磁极极性相反。工作时，各相定子绕组按要求通以单向脉冲电流。开关磁阻电动机的运行原理和磁定子磁极绕组图1开关磁阻电动机结构示意图(6/4极)阻式步进电动机相似，也是按照磁通总要沿磁阻最小的路径闭合这一原理来工作的。在如图l所示的转子位置时，如果给C相绕组通电，则转子将向磁阻变小的方向转动，在图中为逆时针方向。当磁阻达到最小时，即转子4、2极分别与定子C、C‘磁极对齐时，将C相绕组断电，然后给B相绕组通电，转子就可连续旋转。可见，开关磁阻电动机实质上是一种大步距磁阻式步进电动机。开关磁阻电动机的定子极数P，、转子极数P:和相数m之间通常满足P，~Zm一Pr士2的关系。常见的相数m为3或4，定、转子极数配合为6/4、8/6。驱动系统开关磁阻电动机是一种调速电动机，与功率变换器、控制器及位置传感器构成开关磁阻电动机驱动系统(简称SRD)，如图2中虚线框所示。位置传感器向控制器提供转子位置信号，控制器根据转子位置及电动机转速、电流的反馈信息，控制功率变换器中功率半导体开关器件的通、断，使相应的相绕组通电或断电。20世纪90年代以来，人们也在研究无位t传感器的开关磁阻电动机。一一1心_______________」图2开关磁阻电动机驱动系统墓本构成框图控制方法和机械特性在绕组电感随转子位置角增大时，绕组通以电流将产生拖动转矩，而在绕组电感随转子位里角减小时，绕组通以电流则产生制动转矩。绕组通电、断电时的定、转子相对位置角分别称为开通角、关断角。开关磁阻电动机运行控制的关键问题是对开通角、关断角及相电流峰值的控制。在低速运行时，通常采用电流斩波控制，此时开通角和关断角固定不变，通过脉宽调制方法控制通电相绕组的电压有效作用时间，达到限制电流峰值，实现恒转矩调速的目的。在转速较高时，通常采用角度位置控制，通过改变开通角和关断角来改变相电流波形，使转矩随转速成反比变化，实现恒功率调速。当开通角和关断角调节到极限时，转矩将与转速的平方成反比，呈申励直流电动机的特性。
