Types of DC Motor, Shunt wound DC motor, Series wound dc motor, Compound wound dc motor

An Electrical device that Transforms Electrical energy into Mechanical energy is a DC motor. Direct current, the electrical energy used as an input source in a DC motor, is converted into mechanical rotation.

Types of DC Motor

Similar to Generators, there are three different types of dc motor based on how the field winding is connected to the Armature, and they are as follows:

(i) Shunt wound DC motor 

Shunt wound motor with the field winding and armature connected in parallel. The armature current and the current flowing through the shunt field winding are not the same. Shunt field windings are made up of a disproportionately large number of turns of wire with a high resistance in order to generate the required m.m.f. As a result, the shunt field current is minimal in comparison to the armature current.

(ii) Series wound dc motor

A series-wound motor with the armature and field winding connected in series As a result, the armature current is carried by the series field winding. Series field windings must be designed with significantly fewer turns than shunt field windings for the same m.m.f. because the current flowing through a series field winding is the same as the armature current. As a result, a series field winding has a low resistance due to the relatively few turns of thick wire it contains.

(iii) Compound wound motor  

Compound wound motor with two field Windings, one in series and the other in parallel with the Armature. Compound motor connections come in two different Types (like Generators). Short-shunt connections occur when the shunt field winding is directly connected across the Armature Terminals. Long-shunt connections are created when the shunt winding is configured in such a way. That it shunts the series combination of the Armature and series field.
