<p>This electric motor (M) includes a stator (S) comprising a housing (2) in which stator coils (22) are arranged, and a non-rotating portion (4) fixed in rotation with respect to the stator coils (22), a rotor (R) including a rotor shaft (6) and a magnetized ring (14) adapted to rotate with respect to the non-rotating portion (4) of the stator (S), a bearing (12) mounted between the rotor (R) and the stator (S), comprising an inner ring (120) and an outer ring (122), and a sensor unit (16) comprising an encoder (160) fast in rotation to the rotor and a sensing element (162) fixed to the stator (S). The outer ring (122) of the bearing (12) is fast in rotation with the rotor (R), and the sensing element (162) is mounted in an interior volume (V8) of the rotor (R), extending radially between the magnetized ring (14) and the non-rotatable portion (4) of the stator (S).</p> |
