Title (EN) ENHANCED ELECTRICAL MACHINE COOLING
(FR) REFROIDISSEMENT DE MACHINE ELECTRIQUE AMELIORE
Abstract:
(EN) In one embodiment, the present technique relates to a motor having enhanced cooling. The exemplary motor includes a stator core that is formed of a plurality of stator laminations and that is, at least partially, a peripheral surface of the motor. Each stator lamination has a plurality of fins that extend radially outward. When assembled, the fins of adjacent laminations cooperate to form larger fins extending the length of the stator core. These fins enhance the cooling of the motor, by improving heat dissipation of the motor.
(FR) Un mode de réalisation de la présente invention concerne un moteur qui présente un refroidissement amélioré. Le moteur tenant lieu d'exemple comprend un noyau de stator qui est constitué d'une pluralité de tôles de stator et qui constitue au moins en partie une surface périphérique du moteur. Chaque tôle de stator présente une pluralité d'ailettes qui s'étendent en direction radiale vers l'extérieur. Une fois montées, les ailettes de tôles adjacentes coopèrent afin de former des ailettes plus grandes qui allongent la largeur du noyau de stator. Ces ailettes améliorent le refroidissement du moteur en améliorant la dissipation de chaleur du moteur.
