Abstract
An electric compressor and a refrigeration device having the same are provided. The electric compressor includes: an electric motor having a stator and a rotor; a compressing mechanism having an eccentric shaft rotatably and slidably connected to the rotor and defining a compressing chamber therein, the compressing chamber being configured to perform a compression by the eccentric shaft; and a torque damping device configured to connect the rotor with the eccentric shaft, in which during the compression of the compressing chamber, a difference between a rotation angle of the eccentric shaft and a rotation angle of the rotor is a phase angle which is increased and decreased.
