What is an Electric Motor ?

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 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

Power Flow in Inductive CircuitsPower flow through an inductive impedance involves voltage sources and a load with a resistor and inductor.Phasor DiagramsPhasor diagrams visually represent voltages and currents in a circuit, helping to understand power conditions.Power Equation of Synchronous GeneratorThe power equation of a synchronous generator relates the voltage, current, and phase angles to determine power output.Maximum Power Output ConditionsMaximum power output in alternators and synchro

What is an Electrical Generator ?Generator Working PrincipleAn electric generator works by moving a conductor through a magnetic field, inducing an electromotive force (EMF) based on Faraday’s law of electromagnetic induction.Fleming’s Right Hand RuleThis rule determines the direction of EMF, using thumb for motion, first finger for magnetic field, and second finger for EMF direction.AC vs. DC GeneratorsAC generators use slip rings to maintain the alternating nature of the generated current, whe
