# Machine Power Range Calculator

Posted by Dinesh onCalculate **power range for a machine** by using this simple pump and motor hydrostatic transmissions calculator online.

If output shaft torque and output shaft speed are known, the Power Range for a machine can be found by the following formula:

PRm = (Ts)(Ns)/CNote: Be sure to use maximum locked rotor torque when replacing electric motors._{2}(Er)

## Power Range for a Machine Calculation

### Formula:

PRm = [(Ts x Ns) / (C_{2} x Er)]

Ts = Maximum shaft torque

Ns = Maximum shaft speed (RPM)

C

_{2}= A constant to convert to units of power [HP (63025) and Kw (95493)].

Er = Final drive ratio efficiency
