An electric motor including a rotor (10) mounted on a motor shaft (18) for rotation around a stator (11), the rotor (10) including a generally cylindrical wall (12a) and a rotor top (12b) generally closing the cylinder of the rotor wall (12a), the rotor (10) being connected to the motor shaft (18) by a connecting device (20), the connecting device (20) being received within an opening in the rotor top (12b) and having an aperture for receiving the motor shaft (18) as an interference fit which prevents of rotation of the shaft (18) with respect to the connecting device (20), the connecting device (20) including a first radially outwardly extending formation (21b) at a first side of the rotor top (12b), and a second radially outwardly extending formation (21c) at a second side of the rotor top (12b) such that the rotor top (12b) is received between the first and second radially outwardly extending formations (21b, 21 c), and there being a spacer (22) between the first radially outwardly extending formation (12b) and the first side of the rotor top (12b), the spacer (22) including teeth (22a) which dig into the first side of the rotor top (12b) and the first radially outwardly extending formation (21b) to prevent of rotation of the connecting device (20) with respect to the rotor (10). <IMAGE> |
