Stator core classes

Ex :Stator core class: 50 A 350

50 - Value of iron loss multiplied by

A - Symbol denoted non-oriented magnetic steel sheet

350 - Denotes the thickness of plate

The coils are inserted into the stator slots, which have parallel walls to provide a snug fit between the coils and the stator iron. Slot wedges hold the coils in place. Coil ends are connected into the proper groupings to provide the configuration of poles, voltage, and other parameters for which the machine is rated. In our case, each conductor layer has 14 coils insulated by proper insulation. Mica is used in between two conductor layers.
