BLDC window lift motor system
A powered actuator unit for use in a closure system of a motor vehicle. The powered actuator unit includes a common housing configured to house a brushless DC (BLDC) electronic motor unit, a gear drive unit, a shift support arrangement, and a controller arrangement. The motor unit has a stator unit that includes a plurality of electromagnetic subassemblies each having a carrier and a winding unit. The carrier includes an outer ring segment being planar and an inner ring segment being arcuate and a web segment interconnecting the outer ring segment and the inner ring segment and the plurality of electromagnetic subassemblies are each adapted to abut one another in an annular arrangement upon assembly. The outer ring segments define an outer peripheral surface of the stator unit having a polygonal cross-section and the inner ring segments define a rotor cavity having a circular cross-section.
