What is Construction of DC Motor?

DC Motor Definition

A DC motor is defined as a device that converts direct current electrical energy into mechanical energy.

A DC motor is constructed with:

A Stator
A Rotor
A Yoke
Poles
Field windings
Armature windings
Commutator
Brushes

Stator and Rotor

The stator is the stationary part with field windings, and the rotor is the rotating part causing mechanical motion.

Field Winding in DC Motor

Field winding, made of copper wire, generates a magnetic field for rotor operation by creating electromagnets with opposite polarities.

Commutator Function

The commutator is a cylindrical structure that relays current from the power supply to the armature winding.

Brushes and Their Role

Brushes made of carbon or graphite transfer current from the static circuit to the rotating commutator and armature.

How do I change the motor orientation in a star triangle connection?

In a Star-Delta or Y-delta connection, changing the direction of the motor can be achieved by changing the phase sequence applied to the motor windings. The direction of the motor depends on the power supply phase sequence, that is, the order in which the three phases of the power supply reach the motor winding. The following are the specific operation steps and principles:Star connection (Star/Y connection)Star connection principle: In a star connection, one end of the three windings is connect

Armature Winding

Armature Winding

Armature winding definitionThe armature winding in an alternator is the arrangement of coils to generate electricity and is essential to its operation.Type of armature windingSingle-phase armature windingSingle-phase armature windings can be centralized or distributed.Centralized armature windingWhen the number of slots on the armature equals the number of poles in the machine, the central winding is used. This winding type provides maximum output voltage, but is not always fully sinusoidal. The
