Abstract
The invention provides a stator for a three-phase induction motor including a core having a plurality of slots that receives wire. The stator further includes a first phase winding wound on the stator having first and second wires electrically connected in parallel. The first wire forms a first group of coils having a first pattern and the second wire forms a second group of coils having a second pattern different than the first pattern. The invention further provides a winding method for the stator.
