[0022] (1) In this solution, by forming air inlet and air flow channels inside and on the outer wall of the entire motor rotor core, the air flow can quickly flow in the channels inside the entire motor rotor core, improving the heat dissipation performance of the entire motor rotor core. When combining the entire motor rotor core and the rotating shaft, the second fixing plate on the rotating shaft passes through the slot and inserts into the corresponding installation opening, and then the rotating shaft is rotated to move the second fixing plate on the rotating shaft in the same trajectory direction, so that the jacks on the second fixing plate are inserted into the corresponding fixing columns, increasing the connection stability between the rotor core laminations and well reducing the looseness between the rotor core laminations;
