減速機是一種動力傳達機構，利用齒輪的速度轉換器，將馬達的回轉數減速到所要的回轉數，并得到較大轉矩的機構。
減速機的作用
1、降速同時提高輸出扭矩，扭矩輸出比例按電機輸出乘減速比，但要注意不能超出減速機額定扭矩。
2、減速同時降低了負載的慣量，慣量的減少為減速比的平方。大家可以看一下一般電機都有一個慣量數值。減速機的種類 一般的減速機有斜齒輪減速機(包括平行軸斜齒輪減速機、蝸輪減速機、錐齒輪減速機等等)、行星齒輪減速機、擺線針輪減速機、蝸輪蝸桿減速機、行星摩擦式機械無級變速機等等。

兩噴嘴氣動測頭具有兩個相對的噴嘴孔，常用于測量孔的內徑，而兩噴嘴的氣動塞規則主要用于測量外徑。直線度：氣動量儀另一個常用的地方是用于動態的測量孔的直線度或者彎曲度，在這樣的測量中，一個特制的氣動測頭可以簡單快捷的測量出被測工件內孔的直線度。平面度：測量平面度，是通過使工件平貼在一個有著空氣噴嘴的固定平面上移動實現的。這樣測量平面度快速、方便、簡單而且準確。平均值：多噴嘴均勻分布在一個圓面上的測量工具，可以為使用者完成平均值的測量。

　　b) 價格高，控制器要求高；
　　c) 易形成共振，因為任何一件東西都有一個固有振動頻率，如果無刷電機的振動頻率與車架或塑料件的振動頻率相同或接近時就容易形成共振現象，但可以通過調整將共振現象減小到程度。所以采用無刷電機驅動的電動車有時會發出一種嗡嗡的聲音是一種正常的現象。
　　d) 腳踏騎行時較費力，是電力驅動與腳踏助力相結合。 有刷電機優缺點？
　　優點：
　　a) 變速平穩，幾乎感覺不到振動；
　　b) 溫升低，可靠性好；
　　c) 價格低，所以被較多廠家選用。
　　缺點：
　　a) 碳刷易磨損，更換較為麻煩，壽命短；
　　b) 運行電流大，電機磁鋼易退磁，降低了電機與電池的作用壽命。
