Abstract
The utility model provides a suspension rotor motor. The suspension rotor motor includes a rotor arranged on a rotating shaft and annular supporting seats which are arranged at two ends of the rotating shaft and are used for pivoting the rotating shaft; the two ends of the rotating shaft are circumferentially and uniformly provided with at least two fan-shaped bosses; ventilation cavities are formed in the rotating shaft in a radial direction where the bosses are located; and an air pumping device provides air pressure for the ventilation cavities. According to the suspension rotor motor of the utility model, gas of which the pressure is higher than atmospheric pressure in the ventilation cavities in the bosses is utilized to make the bosses separated from the annular supporting seats, such that rotating shaft can suspend like a hovercraft, and therefore, a lubricant is not needed to be used in the motor, and problem of wear and lubricant deterioration can be solved.
