Brush holding assembly for an excited-rotor electric machine

A brush holding assembly for an excited-rotor electric machine, comprising:

• a casing provided with at least two ducts mutually flanked to each other and developing along a preferential direction between a first end and a second end;
• said second end being open and accessible;
• at least two brushes housed and capable of sliding each in a respective duct and projecting externally to said second end;
• a connecting member arranged to connect with an electric current generation unit associated with said casing at said first end of the ducts;
• wherein it comprises:
• presser members associated with the brushes and configured to push said brushes in the direction of the second end in order to keep them pressed on the respective tracks of a rotating manifold of a rotor;
• at least two conductive elements developing along said preferential direction, each operatively interposed between a respective brush and said connecting member and configured to deform along said preferential direction in order to follow the movement of the brush imparted by the presser members,
• wherein said casing comprises fixing means externally faced to it and shaped to allow a reversible coupling of the casing with the housing of the manifold.
