ASTK台湾原装齿轮减速机：降低电机运转速度，同时提高输出扭矩（需要和齿轴电机搭配方可使用）。
齿轮减速机是一种相对精密的机械，使用它的目的是降低转速，同时提高输出扭矩。
减速机一般用于低转速大扭矩的传动设备，把马达高转数运转的动力通过减速机输入轴上齿数小的齿轮啮合输出轴上的大齿轮来达到减速的目的，可将马达的迴转数减速到所需要的迴转数，大小齿轮的齿数之比，就是传动比。
具有低噪音、体积小、高扭力、重量轻、寿命长、免保养等特点
GN-中负荷用，寿命长。
GU-重负荷用，寿命长，耐冲击。
减速机的比数有：1：3至1：180比。
马达有圆轴和齿轮轴两种，只有齿轮轴才能够与减速机直结。
●中间减速机：当单一的减速机不能得到所需的减速比时，可以加装一个或多个中间减速机，来获取更大的减速比。
可搭配的马达功率有：3w.6w.10w.15w.20w.25w.40w.60w.90w.120w
减速机的外形尺寸有：60*60mm.70*70mm.80*80mm.90*90mm
GN/GU都有1：10中间减速机。
产地：台湾（原装正品）,有现货。
