Abstract

An electric motor (1) for automotive traction comprising: a stator (4) provided with a plurality of electrical windings (11), which are distributed around a motor longitudinal axis (A); a rotor which is accommodated in the stator (4) with the capability of rotating about said motor longitudinal axis (A); and an inner electric circuit (7), which connects said electrical windings (11) to an external terminal block (6) so as to allow the passage of electric current to and from said electrical windings (11), and includes an annular body (20) comprising: a series of annular flat-wires (21), which are made of electrically conductive material and are arranged one above the other so as to form a tubular stack; a tubular jacket (22), which is made of electrically insulating material and encloses within its annular wall the stack of annular flat-wires (21), isolating the individual annular flat-wires (21) from each other; and a series of longitudinal rods (24), which are made of electrically conductive material, protrude from one of the two axial ends of the tubular jacket (22), and at the same time extend inside the annular wall of the tubular jacket (22) until they reach and electrically connect to respective annular flat-wires (21).
