The invention discloses a magnetic suspension motor with high reliability vibration compensation, including a motor body, First leg, Heat dissipation rib, second leg, bearing cap, end cap, Position sensor, impeller, rotor, demarcation line, limit ring, mounting shaft, axial cushioning mechanism, Iron core, impeller blade, electrostatic precipitator, Filter screen and seal cover, the bottom side ofthe motor main body is provided with a first leg, one side of the first leg is provided with a second leg, one side of the motor main body is provided with a rotor sleeve, the other side of the motormain body is provided with an end cover. The side end of the rotor sleeve is provided with a finite position ring, the middle part of the limit ring is provided with a position sensor, and one side of the position sensor is provided with a rotor. Under the high-speed operation, the phenomenon of the rotor jumping can be eliminated by using an axial cushioning mechanism, and the axial force of therotor can be counteracted, so that the movement of the rotor is stable, and the labor intensity of the working personnel is reduced.
