Title
(EN) DEVICE FOR ATTACHING MAGNETS TO ELECTRIC MOTOR STATOR OR ROTOR YOKES
(FR) DISPOSITIF DE FIXATION D'AIMANTS SUR CULASSE DE STATOR OU DE ROTOR DE MOTEURS ELECTRIQUES
Abstract
(EN)
A device for attaching magnets (3) to an electric motor stator or rotor yoke (1) comprises clips (2a, 2b, 2c, 2d) attached to said yoke (1), wherein each clip has a base portion (14) attachable to said yoke, and two flanged side fins (18) for attaching said magnets, and the device is characterised in that the yoke (1) and the base portions (14) each have co-operating attachment means for retaining the clips at least in a radial direction of the cross-section of the yoke (1) and in that the attachment means co-operate with each other in order to attach the base portions (14) to the yoke (1).
(FR)
Le dispositif de fixation d'aimants (3) sur culasse (1) de stator ou de rotor de moteurs électriques comprend des agrafes (2a, 2b, 2c, 2d) fixées à ladite culasse (1), chacune desdites agrafes étant constituée d'une base (14) fixable à ladite culasse et de deux ailettes latérales (18) à rebords destinés à fixer lesdits aimants, et est caractérisé en ce que ladite culasse (1) et lesdites bases (14) comprennent chacune des moyens de fixation coopérant entre eux, assurant le maintien des agrafes au moins dans la direction radiale de la section droite de la culasse (1) et en ce que la fixation desdites bases (14) à ladite culasse (1) est constituée par la coopération desdits moyens de fixation.
