DC Motor Working Principle, Construction and Diagram Explanation

"A 208-' four-pole 60-Hz Y-connected wound-rotor induction motor is rated at 30 hp. Its equivalent circuit components are:Rs= 0.100 0 RR= 0.070 n Xm= 10.0 Q 0.2100 XR 0.210 QPmech 500 W; Pcore 400 WFor slip of 0,05; Find:How much additiona resistance (referred to the stator circuit) would it be necessary to add to the rotor circuit to make the maximum torque occur at starting conditions (when the shaft is not moving)?"

SOLVED:The stator of a 2 -pole wound-rotor motor is powered by a 3 -phase, 50  Hz source. If the rotor is connected to a 3 -phase, 11  Hz source, at what speeds can the rotor turn? If the motor operates at the lower speed does the 11  Hz source absorb or deliver active power?
