# What is rotor balancing weight or key in alternator and its function.

Rotor balancing weight is provided to reduce the excessive vibration due to its high speed rotation. Excessive vibration has some severe impact on the prime mover and alternator. read more

# Cooling scheme of high capacity alternator

The high capacity alternator set is cooled by a shaft mounted fan and a forced cooling fan. read more

# Details of Excitation system of Alternator

Excitation system of Alternator is one of the most important topics of Electrical Engineering. DC voltage is responsible to generate Magnetic field in alternator. This DC voltage can be supplied to the alternator separately or may be produced from the AC current produced by it thorough conversion. This mechanism is called excitation system. We all … Continue reading Details of Excitation system of Alternator read more

# Brief insight on synchronization of alternator or generator.

When two or more electrical generating sets or systems are paralleled to the same power distribution system, the power sources must be synchronized properly. Without proper synchronization of the oncoming unit or system, power surges and mechanical and electrical stress will result when the tie or generator breaker is closed. Effect of synchronization failure. Under … Continue reading Brief insight on synchronization of alternator or generator. read more

# A brief insight to modern brush less excitation system of alternator.

[ada] Basics of modern brush less excitation system of alternator. We all know the classic theory of Faraday’s law of electromagnetic induction, that when there is relative motion between a conductor and magnetic field then voltage is induced in the conductor. So we got two basic things here 1.Magnetic field, 2. Rotation. This magnetic field … Continue reading A brief insight to modern brush less excitation system of alternator. read more

# Alternator basic characteristics- what needs to know.

Alternator Rating: Alternators are rated according to the voltage they are designed to produce and the maximum current they are capable of providing. The maximum current that can be supplied by an alternator depends upon the maximum heating loss that can be sustained in the armature. This heating loss (which is an I2R power loss) … Continue reading Alternator basic characteristics- what needs to know. read more

# Alternator excitation control principle in different brands of alternator.

The basic of Automatic voltage regulator for all brands of Alternator are same.The current sensing and voltage measuring is done as requirement for AVR calculation. read more

# DC Generator basics and answers to some confusions.

DC generator basics is that it is the combination of ac generator generating ac current then converted to dc by commutator and slip ring. read more
