Abstract
The utility model discloses a motor end cover and a motor provided with the motor end cover. The motor end cover has a sandwich structure with an inner cavity. The external end surface of the motor end cover is provided with a first ventilating opening and a second ventilating opening. One part of flowing air flows out through the first ventilating opening, and the other part of the flowing air flows out through the second ventilating opening via the above mentioned inner cavity. The distance between the first ventilating opening and the center of the motor end cover is greater than the distance between the second ventilating opening and the center of the motor end cover. The distance between the second ventilating opening and the center of the motor end cover is less than the distance between an air channel of a stator external wall and a central line of a drive shaft.
