A threephase, $4$pole, self excited induction generator is feeding power to a load at a frequency $f_1$. If the load is partially removed, the frequency becomes $f_2$. If the speed of the generator is maintained at $1500$ $rpm$ in both the cases, then $f_1,f_2> 50Hz$ ... $f_1< 50 Hz$ and $f_2> 50 Hz$ $f_1,f_2< 50Hz$ and $f_2> f_1$ $f_1>50 Hz$ and $f_2< 50 Hz$

A $15$ $kW$, $230$ $V$ $dc$ shunt motor has armature circuit resistance of $0.4$ $Ω$ and field circuit resistance of $230$ $Ω$. At no load and rated voltage, the motor runs at $1400$ $rpm$ and the line current drawn by the motor is $5$ $A$. At full load, the motor draws a line current of $70$ $A$. Neglect armature reaction. The full load speed of the motor in $rpm$ is _________.

A $4$pole, separately excited, wave wound $DC$ machine with negligible armature resistance is rated for $230$ V and $5$ kW at a speed of $1200$ rpm. If the same armature coils are reconnected to form a lap winding, what is the rated voltage (in volts) and power (in kW) ... if the field circuit is left unchanged ? $230$ and $5$ $115$ and $5$ $115$ and $2.5$ $230$ and $2.5$
