ASTK臺灣原裝齒輪減速機：降低電機運轉速度，同時提高輸出扭矩（需要和齒軸電機搭配方可使用）。
齒輪減速機是一種相對精密的機械，使用它的目的是降低轉速，同時提高輸出扭矩。
減速機一般用于低轉速大扭矩的傳動設備，把馬達高轉數運轉的動力通過減速機輸入軸上齒數小的齒輪嚙合輸出軸上的大齒輪來達到減速的目的，可將馬達的迴轉數減速到所需要的迴轉數，大小齒輪的齒數之比，就是傳動比。
具有低噪音、體積小、高扭力、重量輕、壽命長、免保養等特點
GN-中負荷用，壽命長。
GU-重負荷用，壽命長，耐沖擊。
減速機的比數有：1：3至1：180比。
馬達有圓軸和齒輪軸兩種，只有齒輪軸才能夠與減速機直結。
●中間減速機：當單一的減速機不能得到所需的減速比時，可以加裝一個或多個中間減速機，來獲取更大的減速比。
可搭配的馬達功率有：3w.6w.10w.15w.20w.25w.40w.60w.90w.120w
減速機的外形尺寸有：60*60mm.70*70mm.80*80mm.90*90mm
GN/GU都有1：10中間減速機。
產地：臺灣（原裝正品）,有現貨。
