A symmetrical double-layer concentric wiring method applicable on an electric power/mechanical power conversion device capable of having N poles corresponding to the plural coil grooves for coil winding, in which the method comprises the following steps: (a) laying a first major winding group into a plurality of coil grooves corresponding to (N/2) poles in a variable pitch way; (b) laying a second major winding group into a plurality of coil grooves corresponding to (N/2) poles in a variable pitch way; thereby completing a first layer of winding by carrying out the step (a) and the step (b); (c) laying the second major winding group completed with the first layer of winding into a plurality of coil grooves corresponding to the (N/2) poles in the step (a); and (d) laying the first major winding group completed with the first layer of winding into a plurality of coil grooves corresponding to the (N/2) poles in the step (b); thereby completing a second layer of winding by carrying out the step (c) and the step (d).
