WebN (rpm) is the speed of the motor V => Input DC Voltage I => Input DC Current For Single phase AC motor torque formula: T = V x I x pf / (2 x pi x N (rpm) / 60) V => Input AC Voltage in volts (line to neutral voltage) I => … WebNov 17, 2024 · The simplest way to find the ratio of the required pulley is to divide the driven component (pump) by RPM. For example, if the pump RPM is 1070 for full output, while the motor is 1750 RPM, the ratio of the required pulley would be (pump RPM) divided by the motor RPM, or: 1070 / 1750 = 0.611. Going by our above example, your pulley ratio must ...
