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