Abstract: The present invention relates to a rotor assembly for an electric water pump. More specifically, the present invention relates to a rotor assembly for an electric water pump, capable of reducing a damage to a bearing. According to the present invention, the rotor assembly for an electric water pump comprises a shaft, a core, a can, and a pair of caps. The core has a magnet mounted thereon and is engaged with the shaft by having a groove formed in a way that a bump is formed on both ends in an axial direction from an inner circumferential surface in a radial direction. The can surrounds an outer circumferential surface of the core so that both ends of the can protrude from both ends of the core. The pair of caps surround both ends of the core, wherein outer side surfaces of the caps are engaged with both ends of the can in a radial direction and inner side surfaces are inserted into the groove of the core to be engaged with the shaft. According to the present invention, an inner side surface of the can does not protrude in an axial direction of the core such that the bearing mounted on both ends of the core comes in contact with a flat plate of the caps. Accordingly, the contact surface of the bearing becomes broader and thus, the load is prevented from being concentrated on a small local part of the bearing. Therefore, it is possible to reduce a damage to the bearing.
