calculation power

[MARCOC]

Hello everyone

I have to move a mass from stops to a speed x...after that keep that speed for a stretch of length s...

calculation of the power required to achieve this speed with an acceleration established by me.. once you arrive at the desired speed ...may I lower the power of the engine to stay at constant speed? ? ? ?

I think you have to understand two concepts:
1) user power, which can be variable depending on external disturbances
2) engine power, which follows the characteristic curve for each type of engine.

then you will have to select a (electric) engine that has the power necessary to face the acceleration of the mass inertia to accelerate (oversized equal to the service factor) and then if you stay at constant speed and the torque decreases because you have to win only the friction will consume less power. but the engine always remains

thank you so much is what I wanted to know
