How to slow down a 12 volt dc motor
WebApr 14, 2024 · If you want to reduce the air flow by 20%, 0.8 x full flow, reduce the voltage to the square root of 0.8 = 0.89 x 12 = 10.7 V. The mechanical power required will be the full-speed power multiplied by 0.89 cubed, but the motor may only be 50% efficient, so estimate the electrical power at 22 watts. The required current would be about 2 amps. WebMay 11, 2024 · The motor pulley would need to be somewhere between 2" and 3". It's a ratio. Divide 3400 by the speed you want to get your ratio. Then divide 10.25 by the ratio for the small pulley. 800 would be midway and would take a 2.5" pulley on the motor. 10.25 X 800 ÷ 3400 =2.41" 2.5" Off the shelf. Quote.
