Title: Rotary electric machine of permanent magnet
Inventor: KOBAYASHI HIDEAKI
Filed: 1978-10-04
Abstract: PURPOSE: To manufacture a permanet magnent rotor appropriate to a synchronous machine, by preparing the same number of line-symmetric trapezoidal permanent magnets as poles and annularly placing the permanent magnets in a prescribed  positional relation to one another in a rotor core.  
     CONSTITUTION: As for a four-pole machine, four line-symmetric trapezoidal permanents 1a∼1d are prepared. A magnetic pole side a of each permanent magnet, which is longer than other sides c, d, is magnetized as an N-pole. Another magnetic pole side b of the magnet is magnetized as an S-pole. The magnets are annularly placed so that the magnetic pole sides a or b face the sides c of the adjacent magnets across a gap 3. The gap 3 is increased from the side c toward the side d in consideration of the number of magnetic fluxes which pass through the gap. Rotor core segments 4a∼4d, which are provided with slits 8, 9 leaving bridge parts 6, 7 in order to increase the reluctance, are arranged around the permanent magnets 1a∼ 1d, thereby constituting a rotor.

Abstract: PURPOSE:To keep burrs in the same direction for extending the service life of a cutting mold and reducing production cost by providing a frictional and Jug section on a pair of rotary cutting blades having an approximately H-cross section, and continuously feeding and cutting a long electrode plate material therewith. CONSTITUTION:When an electrode plate material is cut with a pair of rotary cutting blades B and C, the front key portion thereof is in the state of an approximately H-cross section (a) and the side is in (b) state. The electrode plate as a conductive material constitutes a positive electrode active material 1a, and this material 1a is filled with a core 1b of a metal porous body. In addition, the electrode plate material is continuously fed in an arrow direction with the rotary cutting blades B and C.
