1 a 240 dc motor takes an armature current of 20a when

1. A 240 dc motor takes an armature current of 20A when running at 960 r/min. The armature resistance is 0.2ohm. Determine the no load speed, assuming negligible losses.

2. A 220 dc shunt motor has a srmature resistance of 0.3ohm. Calculate

a) resistance required in series with the armature to limit the armature current to 80A at starting

b) the value of counter EMF when the armature current has decreased to 30A with the resistor still in the circuit.
