Claims

[Claims for Utility Model Registration] 1. A core shaft made of a non-magnetic material rotatably supported by a casing, a stator provided on the inner peripheral surface of the casing with a number of magnetic poles corresponding to the number of poles; Three or more coil parts are wound around the core axis, and each coil part is provided with stator facing parts of the number corresponding to the number of poles mentioned above on the same pole side. and the stator facing part of each coil part is "360 degrees/(number of poles x number of coil parts)"
Iron cores are arranged in sequence with pitch angles determined by A rectifying section is provided with segments that are sequentially connected to a coil section having a stator facing section located between the N and S poles, and the width in the rotation direction is set so as not to contact three segments at the same time. A brush that is set smaller than the segment width and that slides into contact with the segment in order to pass a direct current to the lead wire from the same coil part, and is further arranged between adjacent coil parts of the iron core, A direct current rotation characterized in that a spacer unit is pre-assembled in a spacer which is interposed so that the adjacent coil parts do not interfere with each other, and the spacer unit is assembled by being interposed between the coil parts. Electric machine. 2. A DC rotating electrical machine as claimed in claim 1, characterized in that straight portions for positioning are formed on both side edges of the central portion of the iron core.
