Abstract
An electric motor unit includes a casing, a first electric motor and a second electric motor, housed within the casing, a drive shaft operatively connected to the first electric motor and a drive shaft operatively connected to the second electric motor, in which the drive shafts can be rotatably actuated in an independent way with respect to each other around a same rotational axis.
Claims9
An electric motor unit comprising a casing, a first electric motor and a second electric motor, housed within said casing, said first electric motor comprising a first stator winding and said second electric motor comprising a second stator winding, a first drive shaft, which can be rotatably actuated around a rotational axis, operatively connected to said first electric motor, a second drive shaft, which can be rotatably actuated around said rotational axis, operatively connected to said second electric motor, said casing comprising a first half-shell, a second half-shell, and a spacer element interposed between said first half-shell and said second half-shell, said first half-shell, said second half-shell and said spacer element being removably connectable to each other by means of connection means, wherein said first electric motor is housed in a position interposed between said spacer element and said first half-shell and said second electric motor is housed in a position interposed between said spacer element and said second half-shell, wherein in that said first half-shell has, at the portion which during use faces said spacer element, an inner annular seat for at least partially housing said first stator winding of said first electric motor and said second half-shell has, at the portion which during use faces said spacer element an inner annular seat for at least partially housing said stator winding of said second electric motor, said spacer element has at opposite end portions which during use respectively face said first half-shell and said second half-shell, a first inner annular seat and a second annular seat for at least partially housing respectively said stator winding of said first electric motor and said second electric motor.
