Title
(EN) AXIAL FLUX MOTOR WATER PUMP
(FR) POMPE À EAU À MOTEUR À FLUX AXIAL
Abstract
(EN)
An axial flux motor water pump comprising a housing, a cover attached to the housing, a stator mounted within the housing, the stator comprising a plurality of stator poles mounted in a ring, each stator pole comprising an electric wire winding, a rotor journalled to the housing in cooperating relation to the stator on a single bearing, an impeller fixed to an end of the rotor, a plurality of magnets mounted to an end of the rotor in cooperative relation to the stator poles, a seal between the rotor and housing whereby the stator and magnets are in a dry zone, the stator enrobed in thermal potting within the housing; and power electronics contained in the cover.
(FR)
Une pompe à eau à moteur à flux axial comprend un carter, un couvercle fixé au carter, un stator monté à l'intérieur du carter, le stator comprenant une pluralité de pôles de stator montés dans un anneau, chaque pôle de stator comprenant un enroulement de fil électrique, un rotor tourillonné sur le carter en relation de coopération avec le stator sur un palier unique, une hélice fixée à une extrémité du rotor, une pluralité d'aimants montés sur une extrémité du rotor en relation de coopération avec les pôles de stator, un joint d'étanchéité entre le rotor et le carter, le stator et les aimants se trouvant en zone sèche, le stator étant enrobé dans un enrobage thermique à l'intérieur du carter ; et des composants électroniques de puissance contenus dans le couvercle.
