In a dc shunt motor

1. no-load speed is directly proportional to flux/ pole and inversely proportional armature voltage; the speed drops off linearly with load torque.
2. no-load speed is directly proportional to flux/ pole and directly proportional to armature voltage; the speed drops of linearly with load torque.
3. no-load speed is inversely proportional to flux/pole and directly proportional to armature voltage; the speed rises linearly with load torque.
4. no-load speed is inversely proportional to flux/pole and directly proportional to armature voltage; the speed rises linearly with load torque
