The invention provides a stator coil of a direct current motor and a stator coil insulation integration method, and relates to the technical field of the direct current motor. The stator coil of the direct current motor comprises multiple numbers of turns of buses, insulating paper bands and a silicone rubber insulating band, wherein the multiple numbers of turns of buses are configured into the coil appearance of the stator coil of the direct current motor; the insulating paper bands are placed between adjacent two turns of buses in a cushion manner; and the outer sides of multiple numbers ofturns of buses are bundled with the silicone rubber insulating band. The stator coil insulation integration method is used for manufacturing the stator coil of the direct current motor; and by virtueof the stator coil of the direct current motor, the motor input current can be highly increased without changing the motor appearance, so that the motor can output higher power and torsion, and the service life of the motor is not shortened.
