Abstract

The present invention refers to a motor having a constructive arrangement capable of cooling the environment in which said motor is disposed. In a preferred embodiment, said electric motor (101) has a stator (103) disposed inside a rotor (102). This rotor (102) comprises an outer surface (104) that has a first end portion (105) provided with a central hub (108) concentrically surrounded by a radial sector (109) disposed substantially inclined in relation to a perpendicular plane to the central axis of the rotor (102). Said radial sector (109) is convergent upon the central hub (108) and comprises at least a radial opening (110) capable of providing the dispersion of gas contained in an internal environment of the rotor (102). In another preferred embodiment, the rotor (102) comprises at least an agitation element (111) associated to the outer surface (104). This agitation element (111), which is also the object of the present invention, is capable of providing a movement of gas when the rotor (102) rotates. The present invention also refers to a gas compressor (100) having an electric motor (101) mentioned above according to at least one of its preferred embodiments.
