Question

A 120 V, 60 Hz, 0.25 Hp universal motor runs at 2000 rpm and takes
0.4 A when connected to a 120 V DC source. Determine the speed,
torque and power factor of the motor when it is connected to a 120 V,
60 Hz supply and is loaded to take 0.6 A (r.m.s) of current. The
resistance and inductance measured at the terminals of the machine
are 20 ohms and
0.25 I respectively​
