Synchronous Speed

Armature Reaction in Alternator or Synchronous Machine

by

Armature winding in an electrical machine is the winding which carries the load current. Under no-load condition, the armature current is zero. But as the machine is loaded, load current flows through the armature winding and creates magnetic flux. The effect of armature winding mmf or flux on the main working flux created by field … Read more

Concept of Electrical and Mechanical Angles & Synchronous Speed

by

Electrical and Mechanical angles are frequently used in the study of Electrical Machine theory and therefore it is very important to have a crystal clear concept of these two terms and the relationship between them. In this post we will also discuss about the Synchronous Speed and their relationship with Electrical and Mechanical angle. As … Read more
