The invention discloses a novel winding type motor wave winding rotor star point fixing method, which belongs to the technical field of motor manufacturing and motor repairing, and comprises the following steps of manufacturing a flat copper wire into a circle matched with a motor to form a star point connecting wire, welding the star point and the flat copper wire, after welding is finished, cutting a polyester felt into long strips according to the size of the rotor, stacking the long strips in a wave shape, and putting the long strips between the winding and the star point connecting wire,namely between two star points, and firmly binding the winding and the star point connecting wire through a polyester wave rope to form three sets of fixing points, wherein the distance between the second fixing point and the first fixing point is 120 degrees, the distance between the second fixing point and the third fixing point is 120 degrees, and the fixing points are firmly fixed in sequence.The problem that the moto
