Title (EN) BRUSHLESS MOTOR
(FR) MOTEUR SANS BALAI
Abstract:
(EN) A brushless stepper motor is described comprising a first and a second stator (11, 12); and a rotor disc (1) that is rotatable about a rotation axis (Y). The rotor comprises two faces; and is interposed between the first and second stator, so that each face of the rotor is opposed and parallel to a stator. The rotor comprises a first circular series (SM1) of permanent magnets (7M1) arranged at constant angular-step along a first circumference concentric to the rotation axis (Y), each permanent magnet having a parallelepiped shape with a longitudinal axis (X) orthogonal to the rotation axis (Y). Each stator comprises a first constant angular-step circular series of electromagnets (2) with polar expansions (5) facing the permanent magnets of the stator disc.
(FR) L'invention concerne un moteur pas à pas sans balais pourvu de premier et second stators (11, 12) et d'un disque de rotor (1) pouvant tourner autour d'un axe de rotation (Y). Le rotor comprend deux faces et est interposé entre les premier et second stators, de telle sorte que chaque face du rotor est opposée et parallèle à un stator. Le rotor comprend une première série circulaire (SM1) d'aimants permanents (7M1) disposés à pas angulaire constant le long d'une première circonférence concentrique à l'axe de rotation (Y), chacun des aimants permanents ayant une forme parallélépipédique avec un axe longitudinal (X) orthogonal à l'axe de rotation (Y). Chacun des stators comprend une première série circulaire à pas angulaire constant d'électroaimants (2), des extensions polaires (5) faisant face aux aimants permanents du disque de stator.
