Title (EN) MOTOR HAVING SPLIT SPRAY RING FOR COOLING END TURNS
(FR) MOTEUR COMPORTANT UN ANNEAU D'ASPERSION FENDU POUR LE REFROIDISSEMENT DE SPIRES D'EXTRÉMITÉ
Abstract:
(EN) A motor is cooled with a coolant. The motor includes a rotor rotatable about an axis, a stator including a stator core and windings wound about the stator core, a housing enclosing at least a portion of the stator, and a resiliently deflectable spray ring extending circumferentially relative to the axis. The spray ring defines at least one orifice configured to direct coolant on the stator. The spray ring presents first and second arcuately spaced apart ends defining a gap therebetween.
(FR) L'invention concerne un moteur qui est refroidi par un fluide de refroidissement. Le moteur comprend un rotor pouvant tourner autour d'un axe, un stator comprenant un noyau de stator et des enroulements enroulés autour du noyau de stator, un boîtier entourant au moins une partie du stator, et un anneau d'aspersion élastiquement déformable s'étendant de manière circonférentielle par rapport à l'axe. L'anneau d'aspersion définit au moins un orifice configuré pour diriger un fluide de refroidissement sur le stator. L'anneau d'aspersion présente des première et seconde extrémités espacées l'une de l'autre de façon arquée délimitant un espace entre elles.
