Method and apparatus for forming rotor winding for dc coreless motor

Abstract

Abstract PURPOSE: To make winding operation more efficient by the procedure in which winding process is divided into simplified processes involving forming the development pattern of skew winding with enameled wire and then forming its pattern around drum. CONSTITUTION: Skew winding is made with the enameled wire 33 coming from the flyer 32 on the pins 30 and 31 provided in two rows at equal intervals around the circumference of the drums 18 and 19, and the skew wound enameled wire of a definite pattern is transferred by operating it by pressure to the core axle 21 provided near the circumference of the drum to form the winding 34 on the core axle. Then, the core axle is drawn out of the winding 34 to form the rotor winding 35. The method enables one to greatlt reduce the number of processes for forming the rotor winding as compared with the Maxon method, to raise its produtivity, and to more simplify the winding mechanism than polelesscap method. Thus, the automatic operation of winding can be attained. COPYRIGHT: (C)1979,JPO&Japio
