Title: Rotor core
Inventor: KAWANO SHINICHIROU
IPC: H02K19/10
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the shape of a rotor from being transformed, and enable highspeed revolution, by widening the rim end around a slit in the stress concentration part of a core sheet more than those in other parts. SOLUTION: In a core sheet 1, slits 3 are arranged in rows toward the center of a rotor. The slit positioned innermost is the first slit 7, and its width s is made larger than those of other slits 3. Moreover, the width L of the brim around the slit is the same at other part than a stress concentration part 11, but at the stress concentration part 11, the width is made larger than those of other parts. This way, the high-speed revolution of a rotor is enabled by making the width L1 of the rim end around a slit larger than those in other parts. Moreover, a magnetic flux in axis d never flows in q axis direction through the rim end 10 around the slit by making the width of the rim end 10 around the slit in such size that the magnetism is saturated.

Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To fully automate switching and controlling of welding conditions by making the pressurizing of a welding head numerically controlled and also providing a mechanism for measuring the pressurization. SOLUTION: Using a pulse motor 9 in driving an NC machining mechanism, a ball screw 6 and a ball nut 7 are attached to the motor shaft, enabling an electrode 1 to be positioned at an arbitrary speed. In other words, the electrode is moved at high speed to a tentative origin slightly before coming into contact with an object to be welded; then, after slowly descending to be in contact with the object, the electrode stops at the position where a spring 3 is contracted with a limit switch 13 turned ON inside the head; upon completion of welding, the electrode moves at high speed to the position of the tentative origin, ending a series of operation. Then, with a pressurizing force confirmed using a strain gauge 10, and with the abrasion loss (L0 -L1 ) of the electrode determined, switching is performed for the optimum welding conditions according to the length of an electrode and for the pressurizing timing, as preliminarily obtained from experiments. Thus, stable welding is efficiently carried out without the requirement for human intervention.
