A quadrupole (50Hz) three-phase current engine shorted cage is powered by voltage 400V, has line voltage 26A and power factor 0,8. The efficiency grade is 0,9. The losses of the frictions, ventilations, and distributed
losses are ignored. In this engine, we consider the copper losses of the stator to be 30% of the total losses, the copper losses of the rotor to be 25% and the core losses are 45%.

Calculate the :

A) the velocity of the rotation of the engine
B)Power Gap
C)The power conversion
