Can you please assist

Can you please assist with explaining step by step the principles and fundamentals of the following question? i am not wanting the answer just how to work out the problem and understand the problem and acquire the skills to sokve the problem. 1) A four-pole, star-connected, squirrel-cage induction motor operates from a variable voltage 50 Hz three-phase supply. The following results were obtained as the supply voltage was gradually reduced with the motor running on no-load. Stator line voltage 220 164 112 88 42 Stator line current (amperes) 6.8 5.4 3.9 3.8 3.7 Stator power (watts) 470 360 278 244 232 (a) By plotting a suitable graph from these results, determine the total of windage and friction losses, the no load magnetising current I0 (assume no load current I0 is magnetising losses) and the equivalent circuit magnetising circuit parameters R0 and X0. 1b) With locked rotor and 50 volts applied to the stator, the current was 23 amperes and power input 985 watts. The resistance between two lines is 0.5 ohms. If the rotor turns per phase equals the stator turns per phase, draw the equivalent circuit of the motor and determine the values of the various components. Assume the stator phase reactance is the same value as the rotor phase reactance. Many Thanks
