ABSTRACT:
The present invention resides in an improved disc-type, electrical machine having enhanced efficiency and effectiveness. The disc-type, electrical machine comprises a housing unit, a stator connected to said housing unit, a shaft rotatably connected to the stator or housing unit with rotation means, a rotor connected to the shaft wherein the stator surface area and the rotor surface area which are juxtaposed to each other are serrated, thus producing increased magnetic flux areas. The larger surface areas improves heat transfer from the unit's interior and lowers the magnetic flux density between the stator and rotor.
