The reduced parameters of a 50 Hz and 1450 rpm 3-phase asynchronous motor with star connected stator are given below. Rs=2.3 ohms, Rr'= 3ohms. Xsσ (X1)=4 ohms , X'rσ (X2) = 9 ohms, RFe= 450 ohms , Xm= 15 ohms. When applying 400 volts between phases to the motor input, friction losses at motor rated speed consume 3500 watts. Calculate the efficiency of the machine using the L equivalent circuit for this work?

Expert Solution
Step 1
Electrical machines can be either generator or motors. They can be either Ac machines or DC machines.
The electrical machines work on the principle of electro-mechanical energy conversion. The current carrying wires produce magnetic field.
