以用法來說. 有感, 有額外的速度, 溫度感應訊號傳給電變, 即是系統有額外訊號作迴路. 用意在於增強加減速度的線性.

無感, 就是無這感應裝置. 無感亦不代表完全無線性, 迴路在於電變檢測摩打所用消耗的電流差.

有刷無刷分別在於摩打結構. 一般有刷馬達是外則磁石, 軸芯是線圈, 好處是結構和操控線路簡單. 壞處是因為中間軸芯要轉動, 同時亦要有電流通過. 因而需要有電刷連接著而引發兩個問題, 一是電刷的消耗氧化產生電阻耗電, 二是形成轉動阻力.

無刷結構則是反轉, 以磁石為軸芯, 線圈在外, 要保持轉向慣性, 便要用上三個按連續性導通的線圈. 好處是没有有刷的壞處, 不好處就是電變控制比較上複習.
