The invention relates to the field of motors, in particular to a permanent magnet stepping motor, and the motor comprises a casing, a front cover, a rear cover and a rotor core, wherein the front cover used for ventilation and dust prevention is fixedly arranged on the right side of the casing, the rear cover used for heat dissipation is fixedly arranged on the left side of the casing, and the rotor core used for buffering and heat dissipation is arranged in the casing. According to the permanent magnet type stepping motor, the cooling fins, the heat conduction block, the first cooling fan andthe second cooling fan are arranged, the cooling fins make contact with the rotating shaft, the rotating shaft is subjected to primary heat dissipation through the cooling fins, and the heat on the surface of the rotating shaft can be transmitted into the heat conduction block; at the moment, the heat near the heat conduction block enters the rear cover through the first groove and the ventilation pipe, the rotating shaf
