Abstract: The present invention refers to a heatsink (100) mounted between an electric motor (200) and a frequency inverter (300), comprising a plate (110) equipped with protrusions (120) that are cams of the plate (110) which project towards the deflector cover (210) of the motor (200).

Abstract: A rotary electric machine in which the casing containing the rotor/stator assembly comprises an intermediate closing cover that closes one end of the casing, a roller bearing immersed in oil and seated inside the oil tank of the machine, which has a casing with an outer wall that is spaced apart axially from the intermediate closing cover. The spacing between the outer wall and the intermediate closing cover forms a path for air to flow from a fan or a space to be filled with thermally insulating material.

Abstract: A system for fixing the inner air deflector on a deflective cover for a rotating electrical machine, wherein this deflector is fixed onto the deflective cover using a fixing element and a nut placed through elongated holes on flaps of the inner deflector and through elongated holes on the deflective cover, so that the tightening of the fixing set is performed from an outer part of the housing of the machine, enabling adjustment of a gap between an outer edge of blades of a fan and an inner surface of the inner air deflector, in order to minimize the effects of formation of counter-flowing air currents near the gap.

Abstract: A fastening system for the air deflector of a rotating electric machine and, more specifically, to a fastening system allowing variations in the axial position of the deflector and eliminating the need for additional fasteners. In the fastening system of the present invention, the casing has at least a portion of the inner surface configured with a plurality of axially spaced ridges, and the deflector comprises a substantially flat annular plate. The deflector has at least two resilient legs projecting from the annular plate, each leg having a shoulder sized to snap fit against a space formed between the axially spaced of the inner surface of the casing.
