摘要：PROBLEM TO BE SOLVED: To provide an armature, a winding method of a coil of the armature and a DC motor, in which the coil consisting of a concentrated winding type coil around a center portion of an armature core and distributed winding type coils around outer side portions of the armature core, can be wound by a simple process.SOLUTION: Each of a plurality of teeth T of an armature core 6 that are juxtaposed in a circumferential direction comprises: an inside winding part Tc extending in a radial direction from a base end side; and a first branch part Ta and a second branch part Tb branching from a front end of the inside winding part Tc into two in a circumferential direction, and extending in a radial direction. First to ninth coils C1-C9 are wound around all the inside winding parts Tc of the teeth T, and thereafter, tenth to eighteenth coils C10-C18 are sequentially wound over the first branch part Ta of one tooth T of the adjacent teeth T and the second branch part Tb of the another tooth T of the adjacent teeth T.
