Title (EN) PERMANENT-MAGNET BRUSHLESS MOTOR
(FR) MOTEUR SANS BALAI À AIMANT PERMANENT
Abstract: front page image
(EN)A brushless motor comprising a four-pole permanent-magnet rotor (11) and a four-pole stator (12). The stator comprises two stator elements (15, 16) arranged on opposite sides of the rotor. Each stator element (15, 16) comprises a c-shaped core (17) having a back (22) and two arms (23, 24) that extend from opposite ends of the back (22), and a coil (20, 21) wound about the core (17). The free end of each arm (23, 24) defines a pole tip (25), and the pole tips (23, 24) collectively have fourfold rotational symmetry about the rotational axis of the rotor.
(FR)Moteur sana balai comprenant un rotor-aimant permanent tétrapolaire et un stator tétrapolaire. Le stator comprend deux éléments statoriques disposés sur des côtés opposés du rotor. Chaque élément stator comprend un noyau en forme de C ayant une partie arrière et deux bras qui s'étendent depuis des extrémités opposées de la partie arrière, et un bobinage enroulé autour du noyau. L'extrémité libre de chaque bras définit une corne polaire, et les cornes polaires ont collectivement une symétrie de révolution d'ordre 4 autour de l'axe de rotation du rotor.
