Self Excited DC Motor
DC motors that excite themselves have a part and coil of field connected in series or partly so, same for parallel connection. They can also have combination of series and Parallel connections. They also get power from only one place. Three types of self-excited DC motors exist:
- Series DC motor
- Shunt DC motor
- Compound DC Motor
Series DC Motor
It is a motor in which the field is in series with the armature and its starting torque is very high. This means that the same flow of current goes through both the coil and armature. Series motors always go in one direction and their speed is affected by the physical load.
Shunt DC Motor
Shunt motor is a DC motor in which the field is jointed in parallel to the armature and its starting torque is less than that of series motor. Inside the shunt motor the field winding is connected parallel to the armature winding. The field winding is made of more turns of thin wire. Shunt motors are used in applications where continuous speed is required.
Compound DC Motor
Compound Motor is a Motor in which both series and parallel fields are added. Compound DC motors use both parallel and connected field windings. In the armature winding, everything is in series. However, field coils can be shunt or series types.
DC Motor
DC motor is a machine that converts electrical energy of direct current into mechanical energy. In a DC motor, the input electrical energy is direct current which is converted into mechanical rotation.
In this article, we will learn what is DC motor, its Diagram, Construction, Working, types, and applications. We will also compare DC and AC Motors based on various parameters.
