Electrical machine for use in fan, has minimum and maximum air gaps between pole pieces and rotor arrangement, where air gaps are defined by outer circular path and internal circular path, respectively, on stator
Electrical machine for use in fan, has minimum and maximum air gaps between pole pieces and rotor arrangement, where air gaps are defined by outer circular path and internal circular path, respectively, on stator
The machine has a stator body divided into a set of stator sections (24,26) in an axial direction. Minimum and maximum air gaps between pole pieces and rotor arrangement (36) are defined by an outer circular path and an internal circular path, respectively, on the stator. The section (24,26) exhibits related pole piece sections, whose related pole surfaces (34,30) lie in relation to an outer and inner paths.
