常用電機(電鑽)公式

Useful formula 常用電機公式 *Power (Watts)功率 (瓦)= Volts (V) x Amps (I) 伏特 (V) x 安培 (I) *1 Horsepower (HP) =746 Watts 一匹馬力 (HP) =746 瓦 (Ability to move 33,000 lbs one foot in our minute) (能一分鐘內移動33,000磅的東西走一尺) *Efficiency (EFF) =效率 utput Power輸出功率 Input Power輸入功率 *Gear Reduction = 齒輪減速比 Input Speed (Armature)(電樞)輸入轉速 Output Speed (Spindle)(軸心)輸出轉速 *Work Factor (WF) =工作效率 Power 功率 (lower the work factor, higher the torque)機車險
