Abstract: A motor includes a shaft, a rotor shell, a bushing, a bearing, and a thrust plate. The rotor shell is connected with the shaft. The bushing has an accommodating space. The bearing is disposed in the accommodating space, and the shaft is disposed through the bearing. The thrust plate is connected with the shaft, and is disposed between a bottom of the accommodating space and a bottom of the bearing. At least one surface of the thrust plate is formed with a plurality of grooves tapering off from an edge to a center.
