What is Commutation in DC Machine?
Commutation definition
Commutation in a DC motor is defined as the process of converting alternating current generated in the armature winding to direct current using a commutator and a fixed brush.
Continuous contact
This process requires continuous contact between the commutator segment and the brush to maintain the current conversion.
Ideal commutation
Ideal commutation means that the current is reversed within the commutation cycle to avoid sparks and damage.
Current reversal
During commutation, the current flowing through the armature coil reverses the direction, which is essential for the operation of the DC motor.
Improved commutation
Resistance commutation

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 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
