Claims

[Claims for Utility Model Registration] 1. A cylindrical belt-shaped coil made by folding a coil band in which the same number of element coil windings as the number of phases overlap each other with electrical phases and bending them into a wave shape with a predetermined pitch and inclination angle. The stator is fitted into the frame by gluing and fixing the winding wire molded with resin so that the center of the armature core in the axial direction is almost the same as the center of the cylindrical armature winding in the same direction. In a gear winding motor, a cup-shaped ring made of a material with good thermal conductivity is fitted and pressed from the left and right on both the anti-load side and load side coil ends of the cylindrical armature winding. A cylindrical armature-wound motor characterized by: 2. The cylindrical armature-wound motor according to claim 1, wherein the frame and both brackets are fixed with a tightening member or adhesive, and the space between the coil ends on both sides and the cup-shaped ring is impregnated with a good heat conductive resin. . 3. A coil band in which the winding arrangement of the same number of element coils as the number of phases is overlapped with electrical phase is formed by resin molding a band-shaped coil into a cylindrical shape by bending it into a wave shape with a predetermined pitch and inclination angle. In a gear winding motor in which the winding is adhesively fixed so that the axial center of the armature core and the axial center of the cylindrical armature winding are almost the same, and the stator is fitted to the frame. One side end of this stator part is molded integrally with the frame, and when the bracket that closes the other side end is fitted to the end face of the frame, a step is provided at one side end of the frame to prevent the armature from forming. The core is characterized by having a portion facing the side end surface protrude into a cylindrical shape, and the surface of the cylindrical armature winding facing the stator portion abutting against the stator portion and being impregnated with a good heat conductive resin and fixed. Cylindrical armature winding motor.
