Title (EN) GROUPED TOOTH ELECTRIC MOTOR
(FR) MOTEUR ÉLECTRIQUE À DENTS GROUPÉES
Abstract:
(EN) An electric motor may comprise a rotor and a stator comprising rotor and stator teeth, respectively. A non-uniform angular spacing or grouping of rotor teeth may facilitate desired rotational speeds of the rotor.
(FR) L'invention concerne un moteur électrique qui peut comprendre un rotor et un stator comprenant des dents de rotor et des dents de stator, respectivement. Un espacement angulaire non uniforme ou un groupement de dents de rotor peut favoriser l'obtention de vitesses de rotation désirées du rotor.
