兩相電機時，齒槽轉(zhuǎn)矩由四次諧波構(gòu)成，設(shè)計時主要考慮消除四次諧波。定子與轉(zhuǎn)子齒距進行微小變化，使部分交鏈磁通減小，距角特性的峰值轉(zhuǎn)矩減小。目前，銷售的兩相步進電機，除特殊用于制動等方面，一般均采用微調(diào)節(jié)距或改變形狀構(gòu)造，減小齒槽轉(zhuǎn)矩。下圖為兩相步進電機的例子，齒槽轉(zhuǎn)矩使距角特性產(chǎn)生畸變。兩相電機的齒槽轉(zhuǎn)矩為距角特性周期的1/4，即變成四次諧波。定子電流與磁鐵轉(zhuǎn)子磁通的距角特性的理論值為虛線所示的正弦波，此曲線疊加上齒槽轉(zhuǎn)矩產(chǎn)生的四次諧波，合成為粗線描述的畸變轉(zhuǎn)矩曲線，距角特性畸變，則成為非正弦波，引起位置精度變差，振動和噪音變大。
