# What are the structural differences in DC motor and generator?

Contents

## Does DC generator and DC motor have same construction?

Whereas an electrical machine that converts electrical energy into mechanical energy is called Electric Motor. … The DC type machines are classified as DC generators or DC motors. The construction of a DC machine remains the same whether it is a generator or motor.

## What are the similarities and differences between electric motor and generator?

The motor and the generator are almost similar from the construction point of view, as both have a stator and rotor. The main difference between the two is that the Motor is an electric device that converts electrical energy into mechanical energy. The generator is vice versa of that motor.

## What are the basic differences and similarities between a generator and an electric motor?

Both the motor and generator are similar in construction; they consist of a stator and rotor parts. However, in a motor, electrical energy is the input, while the input of a generator is mechanical energy.

## What is the basic principle of a DC generator?

A DC generator operates on the principle of Faraday’s laws of electromagnetic induction. According to Faraday’s law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor.

## What are different parts of electric motor and generator?

An AC Motor/Generator Consists of 4 Main Parts:

• A shaft-mounted wire wound armature (rotor)
• A field of magnets that induce electrical energy stacked side-by-side in a housing (stator)
• Slip rings that carry the AC current to/from the armature.

## What does Faraday’s law state?

This relationship, known as Faraday’s law of induction (to distinguish it from his laws of electrolysis), states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.

## What is major difference between galvanometer and simple electric motor?

Galvanometers and electric motors are both based on the same basic principle of an external magnetic field exerting a force on a current carrying wire. The difference is in how far the device is allowed to move.
