description The utility model discloses an improved structure of a motor rotor, which is provided with a rotor core, wherein the two side surfaces of the rotor core are provided with winding slots; the range of the narrowest point of the iron core width from the winding slot at one side to the winding slot at the other side is 52-53mm; the middle diameter of the winding slot is phi 60-63mm; a fixed slot for installing a plastic pressure plate is convex in the middle of the winding slot; a winding in the slot is fixed by the plastic pressure plate; the plastic pressure plate is inserted into the fixed slot and the winding slot and is pushed in place and clamped and fixed; and the rotor core is appropriately widened. The temperature rise is reduced by reducing the magnetic flux density of an iron core column, and the power and overload capacity are improved; in addition, the installation method of the plastic pressure plate is more economical, and the cost is relatively lower.
