Two methods of connection can be used for the stator or phase windings - Star (or Wye connection); and Delta connection.
In the Star method of connection, 1 end of each phase winding is taken to a central point where they are connected together. This is known as the star or neutral point. The other end of each winding is connected in the bridge rectifier circuit between a positive and a negative diode. Each winding is then always part of a complete circuit.
In the Delta method, the windings are connected in the shape of a triangle. Connections are then taken from each point of the triangle, to the bridge circuit.
