发明名称 ELECTRIC MOTOR AND METHOD FOR MANUFACTURING SAME
摘要 An electric motor has: a rotor; a stator; a housing, an opening for opening the storage space upward, and a notch that is concaved downward from an edge surface surrounding the opening; a lead wire connected to the stator ; a partition wall that is provided on the inside of the notch in order to separate a sealing space for injecting a sealant and a space outside the sealing space from each other, and has a through-hole for allowing the lead wire to be extended to the outside of the sealing space; a cover that can be attached to the housing from above; and an elastic member that is more elastic than the partition wall and disposed under the partition wall. An end surface of the partition wall is disposed on or above a plane surface including the edge surface of the housing.

主权项 1. An electric motor, comprising: a rotor; a stator disposed around the rotor; a housing that has a storage space for storing the rotor and the stator, an opening for opening the storage space to one side of an axial direction along a central axis of rotation of the rotor, and a notch that is concaved from an edge surface surrounding the opening toward the other side of the axial direction; a lead wire connected to the stator; a partition wall that is provided on the inside of the notch of the housing in order to separate a sealing space for injecting a sealant for covering at least a part of the stator and a space outside the sealing space from each other, and has a through-hole for allowing the lead wire to be extended to the outside of the sealing space; a cover that can be attached to the housing from the one side of the axial direction; and an elastic member that is more elastic than the partition wall and overlapped with the partition wall in the axial direction, wherein an end surface of the partition wall or of the elastic member that is disposed on the one side of the axial direction is disposed on a plane surface including the edge surface of the housing or on the one side of the axial direction with respect to the plane surface, and the cover has a flat contact surface capable of coming into contact with the end surface of the partition wall or of the elastic member and the edge surface of the housing.
