Abstract: An automatic taping apparatus for taping a conductive member such as a coil wire of a motor has an automatic adhesive supplying mechanism consisting of an adhesive tank, a tube, a gun and a cylinder for controlling the position of the gun for supplying the adhesive on the coil wire; and further, a tape cutting and clamping mechanism provided on a taping head for clamping a starting end and a finishing end of the tape to adhere them on the coil wire and cut the tape.

Abstract: A manufacturing method for a diamond coil for a rotating electric machine comprises bending a straight conductor in a first plane at eight points so as to produce coil leads, coil ends, and coil straight portions. The conductor is next twisted about its longitudinal axis so as to bend the coil ends out of the first plane. The conductor is then bent in two in a second plane, which is perpendicular to the first plane and which includes the longitudinal axis of the conductor, until the two leads of the conductor point in approximately the same direction.

Abstract: An apparatus for the in situ chamfering of DC motor commutator segments 1 separated by insulating spacers 2 is directly mountable on the motor yoke 62, and includes a frame 32 mounting a reversible drive motor 30 and slidably carrying a reciprocating work table 42. A cutter head 44 mounting a chamfering bit 45 is rotatably mounted to the work table by a pin 43 and is swung out of engagement with the commutator segment assembly 11 during each return pass of the work table, during which time the motor rotor is advanced one pitch by a worm driven roller 53.
