What is the equivalent circuit of DC motor?
The equivalent circuit of a D.C Machine Armature: The equivalent electric circuit is used to represent the armature of a d.c generator. It can be represented by three series-connected elements E, Ra, and Vb. The element E is the generated voltage, Ra is the armature resistance, and Vb is the brush contact voltage drop.
What are the types of DC motors and equivalent circuits?
There are 4 main types of DC motors:
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
- Shunt DC Motors. …
- Compound DC Motors.

What is a shunt motor circuit?
In electrical terminology, a parallel circuit is often referred to as a shunt. Hence, DC motors in which the armature and field windings are connected in parallel are referred to as DC shunt motors.
How do you represent a DC motor in a circuit?
Equivalent Circuit of a DC Motor Armature The armature of a DC Motor can be represented by an equivalent circuit. It can be represented by three series-connected elements E, Ra and Vb. The element E is the back emf, Ra is the armature resistance and Vb is the brush contact voltage drop.
What is the working principle of DC shunt motor?
The working principle of a DC Shunt Motor is, whenever a DC motor is turned ON, then DC flows throughout the stator as well as the rotor. This current flow will generate two fields namely the pole as well as the armature.
