DYNAMOELECTRIC MACHINE AND METHODS Abstract of the Disclosure A method of forming a bearing having a body of sintered powder metal. The bearing body includes a plurality of surfaces with interstices in the sintered powder metal defining a plurality of lubricant flow capillary paths through the bearing body communicating with the surfaces thereof, respectively. In this method, at least some of the sintered powder metal of at least one of the surfaces on the bearing body is mechanically worked with respect to the capillary paths communicating with the at least one surfaces, and the capillary paths communicating with the at least one surface are thereby at least re- stricted to a preselected degree limiting the porosity thereof generally at the at least one surface. A dynamoelectric machine, a method of manufacturing a dynamoelectric machine and a method of fabricating a bearing and lubrication system in a dynamoelectric machine and operating the system are also disclosed.
