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

Electric motor

An electric motor including a rotor with a generally cylindrical rotor wall and a plurality of magnetic field producing elements mounted on an inside surface of the rotor wall, the rotor being mounted for rotation around a central stator, wherein the magnetic field producing elements are mounted on the rotor wall by means of a plurality of resilient retaining members, at least one resilient retaining member being located between and engaging with edges of two adjacent magnetic field producing elements, the edges of the magnetic field producing elements extending generally parallel to an axis of rotation of the rotor, the resilient retaining member being elastically deformed so as to exert a retaining force on the magnetic field producing elements.
