摘要： PROBLEM TO BE SOLVED: To provide a stator for a dynamo-electric machine, which is high in space factor and reduces the power loss caused by leakage flux. SOLUTION: This stator 100 is the one for a dynamo-electric machine consisting of a stator and a rotor. This stator 100 includes a stator core 102 which has a plurality of slots in parallel with the rotating shaft of the dynamo-electric shaft, and a stacked plate conductor made of plate conductors in predetermined form and of predetermined number of stacked sheets in press process. For the predetermined form, the stator core 102 has an open end which is open windably. The stacked plate conductor is inserted into the slot of the stator 102, thereby closing the open end of the stacked plate conductor and forming a coil 112. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enable the rise of power generation efficiency and the drop of temperature, by constituting at least a part of a bobbin for field winding of insulating material. SOLUTION: This generator has a bobbin 11 for field winding whose one part at least is made of insulating material, and when a current is applied to a field coil 12, a main magnetic flux 16 is generated in fixed direction by the polarity of current application. Then, an alternating field is generated in a stator 3 by a rotary shaft 5 rotating by the driving force from outside, and electromotive force is generated in a coil wound on the stator 3, thus power generation is performed. A leaked magnetic flux arises between a first pole 7 and a second pole 8, and also a magnetic flux 17 arises in a bobbin 11 for field winding, and the density of a leaked magnetic flux fluctuates by the rotary shaft 5, the core 6, the first pole 7, and the second pole 8 rotating, but eddy current loss does not arise since insulating material is used for the bobbin 17 for field winding. As a result, the rise of power generation efficiency and the drop of temperature can be contrived.

摘要： PROBLEM TO BE SOLVED: To make the width of an electric motor narrow by inserting one end of an electric coil in a slot between teeth of a core and then winding the electric coil around parts of the core which are located between the teeth of the core. SOLUTION: On the inside of a stator core 2 ring, a plurality of coil grooves or slots SL1-24 are formed radially and slot teeth ST1-24 which are projecting sections formed between each two slots SL1-24 are projected toward the center of the ring. Then, one end of each of electric coils C1-24 is inserted into each of the slots SL1-24 and then the coils C1-24 are wound around parts of the ring-shaped core 2 which constitute a main body of the core 2 and which are slots and have no teeth. In short, the electric coils are wound around the stator core 2. By this method, the width of an electric motor can be made narrow.

摘要： PURPOSE: To realize the strong rotor structure of an asynchronous electric machine which is useable under high revolution, without causing increase in losses. CONSTITUTION: A rotor structure 2 has a conductive conductor structure 6 related to a rotary shaft 4, so as to be adjacent to a stator structure 1 of an asynchronous electric machine. A covering layer 7, which is made of a ferromagnetic granular material with a conductivity lower than the conductivity of the conductor structure 6, is applied to the surface of the rotary shaft 4, and the conductor structure 6 is retained with a covering layer 7.
