The voltage equation can be obtained by applying KVL in the above figure. The connection diagram is shown below: Series Wound Motor In the series motor, the field winding is connected in series with the armature winding. VI a is the electrical power supplied to the armature of the motor. Multiplying equation (3) by Ia we get the following equations. Power input = mechanical power developed + losses in the armature + loss in the field. The voltage equations are written by using Kirchhoff’s voltage law (KVL) for the field winding circuit.įor armature winding circuit the equation will be given as: The sum of the incoming currents at A = Sum of the outgoing currents at A. The current, voltage and power equations for a shunt motor are written as follows.īy applying KCL at junction A in the above figure.
Here the field winding is connected in parallel with the armature as shown in the figure below: Shunt Wound DC Motor This is the most common types of DC Motor. Self-excited DC Motor is further divided into shunt wound, and series wound motor.
The detailed description of the various types of motor is given below.Īs the name signifies, the field coils or field windings are energised by a separate DC source as shown in the circuit diagram shown below:Īs the name implies self-excited, hence, in this type of motor, the current in the windings is supplied by the machine or motor itself. The DC motor is generally used in the location that requires a protective enclosure, for example, drip-proof, the fireproof, etc.
The working principle of the dc motor is based on the principle that the current-carrying conductor is placed in the magnetic field and a mechanical force is experienced by it. But the dc motor has a wide range of speed and good speed regulation in electric traction.

The construction of the dc motor and generator are the same. The dc motor converts electrical power into mechanical power. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor.
