WebOct 6, 2024 · The following formula is used to calculate the torque from horsepower. T = HP / (RPM / 5252) T = H P /(RPM /5252) Where T is the torque (pound-feet) HP is the horsepower. RPM is the rotations per minute. To calculate torque from HP, divide the horsepower by the value of the RPM divided by 5252. WebTo calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM. You can also calculate the slip rating by ...

WebMar 3, 2024 · First, consider that 1 HP = 745.7W. If your alternator demand is for example, 2kW, then you need 2.7 HP from the motor to drive it. The details of RPM and torque vs. power you'd have to get from the alternator supplier. Typical alternators were 50-70A at 12V, or about 720W (roughly 1HP.)

How to Calculate the RPM of a Motor - Global Electronic Services
WebThis calculator will measure either horsepower or torque, depending on your selection. When you choose horsepower, this calculator will measure the approximate horsepower of an engine based on the torque of the engine (measured in foot-pounds) multiplied by the RPM of the engine, divided by 5,252 (conversion between foot-pounds and horsepower). WebN1 D1 = N2 D2 WebThe torque delivered from an electrical motor producing 0.75 kW (750 W) at speed 2000 rpm can be calculated as. T = (750 W) 9.549 / (2000 rpm) = 3.6 (Nm) Example - Torque from an Electrical Motor. The torque delivered … parkridge apartments seattle
