Such an approach to the calculation of the driving power necessary for accelerating the suspension is based on the theorem of the change of kinetic energy, i.e., by neglecting the initial speed of the suspension fed to the rotor (putting it equal to zero), we find the kinetic energy of ...
Also take the above example, the power of motor heating is 1 x 1 x 2 = 2 (W), that is to say, the total motor power of 8 watts, the heating power is 2 watts, 6 watts for the rest of the mechanical work. The calculation formula of cable 1.: squeeze before the sheath ...
