With the wire-wound manner and its manner of the amateur coil the coil has the amateur coil which is done the core less motor

摘要

PROBLEM TO BE SOLVED: To provide a coil winding method which can prevent the armature coil of a coreless motor from separation while the efficiency of a flux is improved when the armature coil is wound on a cylindrical resin insulator provided in the coreless motor.;SOLUTION: A magnet wire 7 is laid straight and horizontally on an upper end plane of a cylindrical resin insulator 6 and then made to descend vertically along the outside surface of the resin insulator 6. The descending magnet wire 7 is laid straight and horizontally on the lower end plane of the cylindrical insulator 6 and then made to ascend vertically along the outside surface of the resin insulator 6. The above-mentioned operations are repeated to form an armature coil. With such a constitution, the same force (torque) can be obtained by the application of a smaller current, the power consumption is reduced, the number of manufacturing processes is reduced to reduce the cost of the product and the productivity and economy of the product as a whole can be improved. Further, the stable coil difficult to separate can be obtained.;COPYRIGHT: (C)2002,JPO
