An electric motor has a rotor shaft which is journalled in an axial bearing located within a bearing tube of a stator. To control relative axial movement of the rotor shaft and bearing, a butting ring is fixed, by supporting arms, in the butt end of the rotor shaft. An abutment surface of the butting ring abuts an end face of the bearing. Lubricant pockets are formed in the abutment surface to hold a lubricant. A further supply of lubricant is received within a lubricant storage pocket formed in a surface of said butting ring opposed to said abutment surface. The lubricant storage pocket is connected to the lubricant pockets by way of connecting channels. |
