DC motors can be classified into several types based on the connection between the field winding and the armature winding.
Shunt DC Motor
- The field winding is connected in parallel (shunt) with the armature winding.
- It provides nearly constant speed, independent of the load.
- Applications: Lathes, fans, blowers, machine tools, conveyors.
Series DC Motor
- The field winding is connected in series with the armature winding.
- It provides High starting torque.
- Dangerous to operate under no-load conditions, as the speed can increase excessively.
- Applications: Cranes, hoists, electric traction, elevators.
Long Shunt DC Motor
- The shunt field winding is connected in parallel (shunt) with both the series field winding and the armature. This is in contrast to a short shunt DC motor, where the shunt winding is only in parallel with the armature.
Short Shunt DC Motor
- The shunt field winding is connected in parallel with the armature winding only, rather than with the entire combination of the armature and series field winding.
