If your motor has three windings, typically con- nected as shown in the schematic diagram in Fig. 1, with one terminal common to all windings, it is most likely a variable reluctance stepping motor. In use, the common wire typically goes to the positive sup- ply and the windings are energized in sequence. The cross-section shown in Fig. 1 is of 30◦ per step vari- able reluctance motor. The rotor in this motor has four teeth and the stator has six poles, with each winding wrapped around two opposite poles. With winding number 1 energized, the rotor teeth marked X are at- tracted to this winding’s poles. If the current through winding 1 is turned off and winding 2 is turned on,the rotor will rotate 30◦ clockwise so that the poles marked Y line up with the poles marked 2. There are also variable reluctance stepping motors with four and five windings, requiring five or six wires. The prin- ciple for driving these motors is the same as that for the three winding variety, but it becomes important to work out the correct order to energize the windings to make the motor step nicely. The motor geometry il- lustrated in Fig. 1, giving 30◦ per step, uses the fewest number of rotor teeth and stator poles that performs satisfactorily. Using more motor poles and more rotor teeth allows construction of motors with smaller step angle.
Unipolar stepping motors, both permanent magnet
and hybrid stepping motors with five or six wires are
usually wired as shown in the schematic in Fig. 2, with
a center tap on each of two windings.
In use, the center taps of the windings are typically
wired to the positive supply, and the two ends of each
winding are alternately grounded to reverse the direction
of the field provided by that winding. The motor
cross-section shown in Fig. 2 is of a 30◦ per step permanent
magnet or hybrid motor.
For higher angular resolutions, the rotor must have
proportionally more poles. The 30◦ per step motor
in the figure is one of the most common permanent
magnet motor designs, although 15 and 7.5◦ per step
motors are widely available.
Bipolar permanent magnet and hybrid motors are
constructed with exactly the same mechanism as is
used on unipolar motors, but the two windings are
wired more simply, with no center taps.
The schematic in Fig. 3 shows how such a motor
is wired, while the motor cross-section shown here is
exactly the same as the cross-section shown in Fig. 2.
Each time you step the motor, you electronically
move the equilibrium position S radians. This moves
the entire curve a distance of S radians, as shown in
Fig. 4.

为你提供手工译出的较高级译文，这么长的三段，花了很多时间。如采纳，敬请加分。

如果你的电机有三个线圈，典型的连接法如图一的线路图所示, 1. 用一个终端共同连接所有线圈，那么它最可能是可变磁阻式步进电机。在使用时，公共线通常接正极供电，而绕组则按顺序激活。图一所示的横截面是每步30可变磁阻电动机的横截面。这种电动机的转子有四个齿，定子有六个磁极，每个线圈绕着两个相反的两极。一号线圈通电后，标有X符号的转子齿就被吸引到该绕组的两级。如果通过一号线圈的电流关闭，二号线圈就会打开，转子会按顺时针方向旋转30°，使标有Y的两极与标有2的两级对齐。也有带四、五个线圈的可变磁阻式步进电机，需要五、六条线。驱动这些电机的原理，与有三组线圈电机的原理是一样的，但是，要理出正确的顺序，是线圈逐一启动，从而使电机很好的分步工作，这就变得很重要。
图一里的电机几何图显示的是每步30°的类型，这种电机使最少的转子齿与定子磁极，但表现令人满意。如使用更多的电机极好转子齿，就可以构造步距角更小的电机。 单极步进电机的永久磁铁和混合步进五、六线电机通常都按图二的线路图接线，两个线圈每个都有中心抽头。在使用中，线圈的中心抽头通常连接电源正极，每个线圈的两端则交替接地线，以扭转那个线圈所提供的磁场方向。图二所示的电机横截面，是步距为30度的永久磁铁电机或混合发动机的横截面。要获得更高的角分辨率，转子就必须按比例增加磁极。图中显示的30°步进电机是最常见的永久永磁电机的设计之一，不过步距为15°和7.5°的电机也广泛使用。
双极永久磁铁电机和混合电机的机制构造同用于单极电机的构造是完全一样的，但两个线圈绕线更简单，没有中心抽头。 图三的线路图显示了这种电机是如何绕线的，而这里所显示的电机横截面和图二显示的横截面图式一摸一样的。你每次让电机推进一步，你就通过电子方式移动了平衡位置S弧度，这就将整个曲线移动了S弧度的距离，如图四所示。
