The electric motor includes a cylindrical casing (1), inside which a number of ferrite magnets (9,10) are arranged. An additional moulding of plastic material (12-15) is formed inside the casing in order to produce U-shaped stirrups (4). The stirrups include flexible arms (5,6) whose ends act on the edges of the ferrite magnets (9,10). The end of each flexible arm includes a small hook (7,8) designed to retain the edge of the ferrite magnet. The casing (1) has a cover (2) fitting over one end. This cover includes a bearing for the shaft of the rotor.
