Abstract
(EN)
Disclosed are a motor rotor, a compressor, and an air conditioner, wherein same are applicable to a suspension bearing. The motor rotor comprises: a magnetic portion (1) used for rotating under the action of an energized coil, and a shaft body (2) connected to the magnetic portion (1) and extending in the axial direction of the motor rotor towards the direction away from the magnetic portion (1). The shaft body (2) comprises cavities (3) extending in the axial direction of the shaft body, and connecting portions (5) used for connecting same with a compression working part, with the connecting portions (5) and the cavities (3) being arranged at intervals.
