Motor, gas compressor and agitation element

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.
