ABSTRACT:
A stator for use with a permanent magnet rotor electrical machine is disclosed which stator eliminates ferromagnetic teeth previously used in stator cores. The stator of the present invention uses a winding support structure made of non-magnetizable, non-conductive material to support the stator windings, which may advantageously be prewound prior to installation on the winding support structure. The stator is easily adaptable to liquid cooling, and has substantially reduced losses due to its toothless design.
