A method for starting the winding of an electric motor stator that includes: a stator core having a plurality of teeth; an insulator disposed on each of the plurality of teeth; a coil formed in a concentrated winding manner on each of the plurality of teeth having the insulator; a power supply terminal inserted into a connection side of the insulator and supplying voltage to the coil, the power supply terminal including an insertion section inserted into the insulator and a bent back section bent by 90 degrees vertical to the insertion section and then bent back by 180 degrees in a direction vertical to the insertion section; and a pin having an insulating property and two side surfaces, one side surface being opposite from the power supply terminal and one side surface facing the power supply terminal, and being juxtaposed to the power supply terminal on the connection side of the insulator, said method comprising: at a start of winding of the coil, a first step of forming a two-turn winding portion by winding a magnet wire in a direction away from the said plurality of teeth and around the pin for two turns; a second step, subsequent to the first step, of winding the magnet wire to cross the two-turn winding portion by forming two cross sections (3b1, 3b2), each cross section (3b1, 3b2) being on an outside of the said two turn winding portion and on one of the said side surfaces of the pin; and a third step, subsequent to the second step, of guiding the magnet wire to be hooked on the bent back section. a stator core having a plurality of teeth; an insulator disposed on each of the plurality of teeth; a coil formed in a concentrated winding manner on each of the plurality of teeth having the insulator; a power supply terminal inserted into a connection side of the insulator and supplying voltage to the coil, the power supply terminal including an insertion section inserted into the insulator and a bent back section bent by 90 degrees vertical to the insertion section and then bent back by 180 degrees in a direction vertical to the insertion section; and a pin having an insulating property and two side surfaces, one side surface being opposite from the power supply terminal and one side surface facing the power supply terminal, and being juxtaposed to the power supply terminal on the connection side of the insulator, said method comprising: at a start of winding of the coil, a first step of forming a two-turn winding portion by winding a magnet wire in a direction away from the said plurality of teeth and around the pin for two turns; a second step, subsequent to the first step, of winding the magnet wire to cross the two-turn winding portion by forming two cross sections (3b1, 3b2), each cross section (3b1, 3b2) being on an outside of the said two turn winding portion and on one of the said side surfaces of the pin; and a third step, subsequent to the second step, of guiding the magnet wire to be hooked on the bent back section. at a start of winding of the coil, a first step of forming a two-turn winding portion by winding a magnet wire in a direction away from the said plurality of teeth and around the pin for two turns; a second step, subsequent to the first step, of winding the magnet wire to cross the two-turn winding portion by forming two cross sections (3b1, 3b2), each cross section (3b1, 3b2) being on an outside of the said two turn winding portion and on one of the said side surfaces of the pin; and a third step, subsequent to the second step, of guiding the magnet wire to be hooked on the bent back section.
