ABSTRACT:
An improved armature for a small motor comprising a stator core constructed by laminating a plurality of magnetic plates having a plurality of salient poles projecting radially from a ring section, driving coils wound around coil winding sections created on the salient poles, winding slots created at positions where the salient poles adjoin each other and an insulating holder for insulating connecting sections for connecting end wires of the driving coils and lead wires from the driving coils; wherein the insulating holder comprises a plurality of insulating sections created in a manner communicating with each other in the lamination direction of the stator core to be mounted to the slots; holes penetrating through the insulating sections in the lamination direction for inserting the connecting sections and the vicinity thereof and a linking section for linking an end of each of the plurality of insulating sections. The insulating holder having a plurality of insulating sections and the linking section for linking the insulating sections are created in one body, so that a plurality of insulating sections may be created and handled as one part and the size of the insulating holder can be large, thereby facilitating its handling.
