Motor calculation. The electric power taken by a three-phase motor is given by the following equation. where U is the nominal voltage, I the nominal current, and cos ( the power factor of the motor. These values are stamped into the rating plate of the motor. Knowing the mechanical power, which is the rated power of a motor, losses can be ...

Draw a vertical line BC representing the rated o/p of the motor s per the power scale. From point C, draw a line parallel to o/p line, so as to cut the circle at pint P. Join OP which represents the full load current of the motor to current scale. Operating power factor can also be found out. ... Induction Motor Design (3-Phase) ...

A 3 phase Induction motor is running at 1740 rpm on a 60Hz supply. Calculate the no. of poles, the slip and the rotor frequency. The power supplied to a 3- phase Induction motor is 40 kw and the corresponding stator losses are 1.5KW. Calculate the total mechanical power developed and rotor copper loss if slip is 0.04 per unit.
