WebMar 29, 2024 · 09/15/2015 3:49 PM. Shaft power is the MECHANICAL kW delivered at the motor shaft. Mechanical kW =Torque (N-m) x RPM / 9550. Absorbed power is the ELECTRICAL kW that is drawn from the source in order to produce the Shaft Power. Absorbed kW = Volts x Amps x Power Factor (and for 3 phase, x 1.732) WebIn the case of rotational motion, the analogous calculation for power is the product of torque and angular distance per unit time or simply the product of torque and angular speed. Where: P = Power in W M = Torque in Nm F = Force in N d = Distance in m t = Time in s ω rad = Angular Velocity in rad/s

Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work. In mechanics, the work done by a force F on an object that travels along a curve C is given by … WebP 2 – P c = P m (1-s) P 2 = P m P c = s P 2 Using the formula, The total mechanical power is developed in the rotor is equal to the (1-s) times of the rotor input. The total copper loss is equal to the slip s times of the rotor input. Total mechanical power is equal to the difference between rotor input to rotor copper loss. pltw specialization course
