Abstract: Disclosed is an improvement to the stability of D.C. motor brushes mounted in brush boxes with wings is improved by angling the wings toward the commutator such that the brush spring contacts the brush at one or more points intermediate the ends of the brush. Improved cooling is provided by utilizing an end plate with apertures and a brush plate which in combination with the commutator, provides a brush plate aperture for cooling air flow. In a preferred embodiment, speed variations of the motor can be achieved by selectively disconnecting one or more brushes in a four brush embodiment reducing the torque and rotating speed of the motor. In a preferred embodiment, the use of a diode to interconnect same polarity brushes permits a speed change to be accomplished by selectively connecting one or the other end of the diode.

Abstract: A self contained, "package", bearing system, has relatively rotating and sliding, precisely formed, truncated spherical, journal and bearing surfaces with a high hardness and with a low surface roughness, that operate on a thin hydrodynamic film of pressurized lubricant, when the bearing system is operated under any combination of axial and radial loads. It optionally contains either a supply of dry lubricant, or normally a capillary supported, self-contained reserve of fluid lubricant, and a system of "internally discharging" throwers, for keeping the fluid lubricant within the system, to promote a long operating life.Lubricant re-circulation channels at the ends of the bearing and the inherently lower rates of flow of lubricant from the ends of truncated spherical bearings facilitates achieving long operating life. Grooves and recesses are optionally included in the bearing surfaces for enhancing the axial load capacity.

Abstract: A motor assembly for use in combination with an air handling system such as an automotive blower system for supplying cooling or heating air to a passenger compartment of an automobile. The assembly comprises a support member which is adapted to be mounted on the air handling system. Stationary and annular rotatable assemblies are mounted on one side of the support plate and a printed circuit board including a motor control circuit is mounted on the other side thereof. The stationary assembly has a plurality of winding stages adapted to be electrically energized to generate an electromagnetic field. The annular rotatable assembly has a plurality of permanent magnet elements surrounding the stationary assembly and is adapted to engage a squirrel cage fan for moving air in the air handling system.

Abstract: A method of providing a lubrication system for a shaft journaled in a dynamoelectric machine. In this method, the shaft is lubricated with a solid lubricant of a feeder wick member impregnated therewith during at least a part of the run-in operation of the dynamoelectric machine when it is first energized. A mixture of a lubricating oil and the solid lubricant is then created to effect the lubrication of the shaft by passing the lubricating oil from a storage wick material therefor through the feeder wick member in response to the rotation of the shaft when the dynamoelectric machine is energized.

Abstract: A dynamoelectric machine has a structural component including a partial spherical seating surface having a preselected center of curvature, and a bearing device is adapted for seating association in a plurality of aligned attitudes with the structural component. The bearing device includes a partial toroidal seating surface disposed in seating engagement on the partial spherical seating surface with the seating engagement therebetween generally defining at least a circular line located within a preselected angular range along the partial spherical seating surface in any of the aligned attitudes of the bearing device.A bearing device and wick and bearing assemblies methods of assembling a wick and a bearing and a method of providing a lubrication are also disclosed.

Abstract: In a method of assembling a wick and bearing, the wick is passed into a bore of the bearing through one end thereof, and bridge means on the bearing spanning the bore thereof is captured between bifurcated sections of the wick. In another method of assembling a wick and bearing, wiping sections of the wick are respectively disposed in slots in the bearing intersecting with a bore thereof and a bridge section on the wick is twistably displaced between the wiping sections thereof so as to span across a peripheral portion of the bearing.

Abstract: An illustrated lubrication arrangement substantially prevents end leakage oil from flowing along the shaft to an oil thrower, and also causes end leakage oil to recirculate through wicking material to a feed wick which in turn feeds oil to a bearing clearance. A feed wick includes a feeding portion that extends through a window in the bearing and contacts the shaft. This same wick includes recirculatory pick-up wicks that protrude into a capillary oil collection region at each end of the bearing. The pick-up wicks have a smaller cumulative effective axial length than the feeding tab of the wick. The pick-up wicks also contact the shaft, and they recirculate end leakage oil to the feeding tab because of gradients in oil content within the wicking that interconnects the pick-up wicks with the feeding tab. The pick-up wicks and feeding tab may actually be separate pieces, the capillary interstices of which communicate with each other.
