与单极步进电机不同，双极步进电机每相只有一个单绕组，没有抽头。 为了反转磁极，绕组中的电流需要反转，这意味着双极步进电机驱动通常更加复杂并且通常需要H桥排列。 由于没有公共端，每相有两个引线，典型的两相电机会有四根引线。 尽管双极电机通常驱动更加复杂，但它们确实具有它们的优点，因为更好使用的绕组，双极电机比同重量的单极电机更强大。 这是因为单极步进电机在相同空间中有两倍的导线量，并且在任何一个时间只能使用其一半，这意味着单极电机仅有约50％的效率。(Unlike the monopole stepper motor, the bipolar step motor has only one single winding per phase, without a tap. In order to reverse the magnetic pole, the current in the winding needs to be reversed, which means that the bipolar step motor drive is usually more complex and usually requires a H bridge arrangement. Since there is no public end, each phase has two leads, the typical two phase motor will have four lead. Although bipolar motors are usually driven more complex, they do have their advantages, because the better use of windings and bipolar motors is stronger than the same weight monopolar motors. This is because the unipolar stepper motor has two times of wire quantity in the same space, and it can only use half of it at any time, which means that the single pole motor is only about 50% efficiency.)
