Electric motor with modular stator ring and improved heat dissipation

摘要: A stator ring for an electric motor, the comprising plural sections being molded of insulated ferromagnetic powder. The each have arcuate shoe having a plurality teeth projecting radially therefrom. are adapted receiving coil windings. retained end to by core form complete ring. shoes create expansion gaps between opposite ends thereof when and subjected heat expansion, prevent damage due expansion. is also constituted with improved dissipation mount electronic circuit board some its components in direct conductivity core. Heat dissipated radiation, convection ventilation.
