Abstract
A stator comprises multiple, stacked laminations, which collectively define a core having a number of posts arranged circumferentially about the core. Each post extends into two prongs defining a first slot between the prongs. The spacing between each posts and its two prongs defines a second slot having a radially inner and outer slot. The outer slot geometry has an increasing width extending radially outward from the radially inner end, and transitioning to a decreasing width extending to the radially outer end.
