Abstract
An electric machine has a stator body formed of a coil of concentric layers of amorphous metal tape and slots are formed in one end of the coil for receiving a stator winding. A rotor structure having permanent magnet poles embedded therein is placed adjacent the end surface of the stator and is coupled thereto through the axial gap between the stator and rotor. The magnets are held in place in a nonmagnetic matrix which consists of an epoxy fiber laminate material. By enlarging the outer diameter of the rotor with the epoxy fiber laminate material, the rotor serves as an integral flywheel structure.
