NOVELTY - NOVELTY B The motor has a rotor (1) that is set with a rotating shaft and several permanent magnets which are orderly arranged along a circumferential direction of the rotating shaft. A machine base jacket is sleeved outside of a stator core (2). A machine base is provided with a liquid inlet (3211), a liquid outlet (3212) and a first flow passage (3213). A stator iron core is provided with a second flow passage whose one end is connected with the liquid inlet. A balance disc is sleeved on the rotating shaft of the rotor and is provided in interference fit with the rotating shaft. A column hole is matched with a balance column. Multiple coils are concentrically embedded from outside to inside. Multi-sized coils are reduced, and multiple groups of the windings are interconnected in the adjacent two groups of the windings. The stator iron core, the rotor, the stator winding and the end of the balance ring are coated with a graphene dispersion layer. USE - Ultra-high speed motor. ADVANTAGE - ADVANTAGE B The ultra-high speed motor can generate only less heat, and good heat dissipation effect. The rotor strength is high and the copper consumption is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the ultra-high speed motor. Rotor (1) Stator core (2) Liquid inlet (3211) Liquid outlet (3212) Flow passage (3213)
