RADIAL-FIELD ELECTRIC MICROMOTOR, CYLINDRICAL BODY FOR USE IN THE MICROMOTOR, METHOD OF MANUFACTURING THE MICROMOTOR, AND AXIAL-FIELD ELECTRIC MICROMOTOR

摘要

An electric micromotor comprising a stator winding, a rotor magnet (11) mounted for rotation about a rotor axis (13) and having permanent-magnet poles facing the stator winding, and electrical connection means for the electrical connection of the stator winding to a power source. The stator winding is formed by a cylindrical body (1) having an electrically conductive cylindrical wall (3) provided with longitudinal slots, which extend from an axial end face (15) of the cylindrical body over at least a part of the length of this body, to bound and form axially extending electrical conductors (5) for cooperation with the permanent-magnet poles. The conductors are mechanically interconnected by electrically insulating reinforcement means (19) at the location of the longitudinal slots.
