- A Series Motor Having An Armature And Field Resistance Of 0 1 Q2 Derives A Fan For Which Torque Varies As The Square Of 1 (37.01 KiB) Viewed 34 times
A series motor having an armature and field resistance of 0.1 Q2 derives a fan for which torque varies as the square of the speed. On 220 V, it runs at 300 rpm and takes 25 A. The speed is to be raised to 400 rpm by increasing the voltage. Find the voltage and current assuming the flux is directly proportional to current and frictional losses are negligible.
