Permanent magnet rotor for an axial flux motor

An axial flux motor water pump comprising:

• a housing;
• a cover attached to the housing;
• a stator mounted within the housing, the stator comprising a plurality of stator poles mounted in a ring, each stator pole comprising an electric wire winding;
• a rotor journaled to the housing in cooperating relation to the stator on a single bearing, the rotor comprising a rotor shaft having a rotational axis and either a plurality of magnets or a ring magnet, wherein the plurality of magnets or the ring magnet are mounted on a frame on a first end of the rotor shaft in cooperative relation to the stator poles,
• an impeller fixed to a second end of the rotor shaft;
• a seal between the rotor and the housing whereby the stator and the plurality of magnets or the ring magnet are in a dry zone, the plurality of magnets or the ring magnet and the frame being manufactured in a sintering process comprising:
• adding a first material to a die,
• adding a second material to the die above the first material,
• compressing the first material and the second material within the die, and
• magnetizing the second material;
• a condensate chamber and reservoir comprising a vent hole and a drain hole, wherein the condensate chamber and reservoir is positioned to collect any fluid that may leak past the seal, and the vent and drain hole are open to ambient;
• the stator enrobed in thermal potting within the housing;
• and
• power electronics contained in the cover.
