根據(jù)式θs=π/(2Nr)可知，要使θs越小，Nr越大越好。另外，高分辨率的步進電機的轉(zhuǎn)子結(jié)構(gòu)大致分為PM型、VR型、HB型三種，其中HB型分辨率。由于PM型定子磁極為爪級結(jié)構(gòu)的關(guān)系，定子磁極數(shù)的增加受到機械加工的限制。HB型轉(zhuǎn)子表面無齒，N極與S極在轉(zhuǎn)子表面交替磁化，因此極數(shù)即為極對數(shù)Nr，同樣的，轉(zhuǎn)子磁極Nr的增加也受到充磁機械的限制。VR型轉(zhuǎn)子齒數(shù)與HB型相同時，因不使用永磁體，雖有相同的Nr，但是步距角θs為HB型的2倍，并且由于無永磁磁極，轉(zhuǎn)矩Tm比HB型小。
