摘要： A method of securing a tubular metallic magnet retainer to a tubular metallic frame of a dynamoelectric machine, the tubular frame having an annular internal surface, the steps comprising, forming an annular end surface at an end of said tubular frame that is located at an angle to said annular internal surface of said frame, an intersection of said annular end surface and said internal annular surface of said frame forming an annular first ridge, inserting said magnet retainer into said tubular frame, bending an annular end portion of said magnet retainer into engagement with said annular surface on said frame to thereby form a second annular ridge on said magnet retainer that is aligned with said first annular ridge, moving a welding electrode that has an annular tapered surface into engagement with said second ridge, a shape of said tapered surface on said welding electrode being such that there is annular line contact between a portion of said tapered surface on said welding electrode and said second ridge, and causing a welding current to flow through said electrode and through said first and second ridges to cause an annular imperforate weld to be developed between said first and second ridges.

摘要： The method of the present invention involves setting a penetration threshold as well as a maximum weld time when hot staking armature conductors to the slots of a commutator. To perform each weld, an electrode is forcibly contacted with the top conductor in one of the slots of the commutator. Next, electric current is delivered to the electrode, causing the conductor to heat and begin to deform within the slot. During this time, the electrode moves further into the slot. If the electrode reaches the penetration threshold in the commutator slot before the maximum weld time is reached, current to the electrode is terminated. After terminating current to the electrode, the electrode remains in contact with and applies force to the conductor until the maximum weld time is reached. After the maximum weld time is reached, the electrode is removed from contact with welded conductor.
摘要翻译：本发明的方法包括设置穿透阈值以及将电枢导体热敷在换向器的槽上时的最大焊接时间。为了执行每个焊接，电极在换向器的一个槽中与顶部导体强制接触。接下来，电流被传送到电极，导致导体加热并在槽内开始变形。在此期间，电极进一步移动到槽中。如果在达到最大焊接时间之前电极达到换向器槽中的穿透阈值，则终止电流到电极。在将电流终止于电极之后，电极与导体保持接触并施加力，直至达到最大焊接时间。达到最大焊接时间后，电极与焊接导体脱离接触。

摘要： An apparatus for and a method of brazing copper armature conductors to a commutator during the production of automotive starting motors. In the inventive method, two conductors of the armature are brazed together and are also brazed to the corresponding slot in a commutator in a single step. The process is aided by an inventive brazing clip which includes a cleat or inwardly bent tab that engages the conductor of an armature to hold it in place.

摘要： A frame and magnet assembly for a dynamoelectric machine. The assembly includes an imperforate frame member formed of metallic magnetic material. A one-piece tubular imperforate stainless steel magnet supporting part is disposed within the frame. The magnet supporting part has pockets that contain permanent magnets. The opposite ends of the frame have annular chamfered or tapered surfaces which intersect a tubular inner surface of the frame to define annular ridges. Annular end portions of the magnet support are bent into engagement with the tapered surfaces on the frame to thereby provide ridges on the magnet support that are aligned with the ridges on the frame. The ridges on the frame are welded to the ridges on the magnet support by a welding current that is supplied to a pair of welding electrodes that respectively engage the ridges on the magnet support. The welding electrodes have annular tapered surfaces which have line contact with the ridges on the magnet support.
