Shunt DC motor
In this arrangement, the armature and field coils are connected in parallel (the motor is called 'shunt connected').
AnalysisWith reference to the diagram above,
Normally If is a approxmetely constant and Ra is very small (so V>>Ia.Ra).Therefore the motor speed is approximately constant for a given supply voltage, V. The speed may be controlled by reducing the field If by increasing the field resistor Rf is reduced and the so Φ speed increases.
