Alternator Stator Winding Diagram

The stator frame is used to hold the armature windings in alternators and in case of larger diameter alternators which are slow speed the stator frame is cast out of sections and there are holes for ventilation in the casting itself. This winding is either of wave wound type or lap wound type this being much more common especially for high speed turbo generators. Armature winding in an alternator may be either closed type open type.

Diagrams for the sr4 and other sr4b generators appear at the beginning of this manual. Closed winding forms star connection in armature winding of alternator. The result is three overlapping single phase ac sine wave current signatures a b c. There are some common properties of armature winding.

This will cover rewinding of an alternator stator for use in a wind turbine generator. Understanding the alternator the stator winding has three sets of windings. Each is formed into a number of evenly spaced coils around the stator core. First and most important property of an armature winding is two sides of any coil should be under two adjacent poles.

The diagrams that follow apply to the sr4b generators used with 3500 engines. Three phase current provides a. The recent trends towards such stator construction are more in favour of using mild steel plates which are welded together rather than using castings. Thinking out side box 98827 views.

Two important points regarding this winding should be noted. Coils are laid out in a wave pattern and cross all the polesin wave windings the number of parallel paths ais always two 2 and there may be two or more brush positionswhen two adjacent commutator bars make contact with a brush p2 coils are shorted by the brush in the wave windingbecause wave windings have only two parallel paths this winding is more suited for high voltage low. How to rewind an alternator. Traditionally the use of car alternators is discouraged in favor of homemade slow running axial flux generators.
