Pressure rings are copyrighted. According to the inquiry of relevant public information, Suzhou Yongtaixing Machinery Co., Ltd. applied for a rotor pressure ring on March 1 1 2022, and the patent was granted on July 15, 2022 and expired on March12032. The utility model discloses a rotor pressure ring, which comprises a pressure ring body, wherein the pressure ring body comprises a central hole, a punching groove, a cooling plate and a cooling hole; Punching grooves are evenly distributed around the outer ring of the pressure ring body, and cooling holes penetrate through the pressure ring body; Cooling holes extend along the axial direction of the pressure ring body, are located between the punching groove and the central hole, and are evenly distributed around the central hole, and the cooling plate is annular. The temperature inside the rotor punching sheet is conducted to the cooling plate located outside through the cooling jacket, which increases the heat dissipation area, realizes self-ventilation cooling when the rotor rotates, and improves the working efficiency of the motor; At the same time, the radiating fins arranged on the radiating plate further increase the radiating area, that is, the radiating effect is improved.
