The invention discloses an elevator traction machine equipped with a magnetic suspension outer rotor. The elevator traction machine comprises a main shaft, a stator assembly, a stator coil and a traction wheel; the traction wheel is mounted on the main shaft through a bearing; annular magnetic steels are mounted on two sides of the bearing on the main shaft; the magnetic pole in the inner ring of the annular magnetic steels is N pole; a coil is mounted between the annular magnetic steels and the main shaft; the coil is fixed on the main shaft; the magnetic steels are fixed on the traction wheel; and the outer ring magnetic pole of the coil positioned in the upper half part of the main shaft is N pole while the outer ring magnetic pole of the coil positioned in the lower half part of the main shaft is S pole. According to the elevator traction machine equipped with the magnetic suspension outer rotor, the service life of the bearing can be greatly prolonged; the elevator traction machine can be applied to high-speed elevators at speeds faster than 20 m/s; and meanwhile, the maintenance cost of the bearing is reduced, and the product quality is improved.
