PURPOSE:To obtain circular windings which have varying-speed taps successively without discontinuity of the coils by a method wherein turning direction of a coiling terminal by whch coiling is performed and traveling direction of the wound part are reversed at the end of each varying-speed coil. CONSTITUTION:Coiling is started from a terminal A0 of a complementary winding A and a coiling terminal makes winding in each slot in such a manner that it is turned around the inside and the outside circumference of the yokes of the slots. The coiling of a winding A1 is carried out until the coiling comes to an end X1 by transferring the position of the wound part from one slot to another successively to the certain direction. After the coiling terminal reaches the and X1 of the winding A1 the turning direction of the coiling terminal and the direction of transferring the position of the wound part are reversed and the coiling of a winding A2 is carried out. Then after the coiling terminal reaches the end X2 of the winding A2, the turning direction and the direction of transferring are again reversed and the coiling of a winding A3 is carried out. And at the end of the winding A3, a common terminal COm is formed. |
