shunt motor

A shunt motor is a type of direct-current (DC) electric motor where the field coils are connected in parallel with the armature. This configuration allows for speed control by adjusting the field current. When the field current is maximized, the magnetic flux is strongest, resulting in a lower no-load speed. Conversely, reducing the field current weakens the flux, requiring the motor to rotate faster to generate the same voltage, thus increasing the no-load speed. While this provides a wider speed range, the available torque is reduced at higher speeds due to the weaker flux. Shunt motors are known for their ability to provide accurate speed control and are used in applications requiring precise adjustments. A shunt dynamo refers to either a shunt-wound generator or motor.12
