PURPOSE: A laminated rotor core of a motor is provided to prevent problems due to a motor overheating by emitting heat generated in a motor driving process through through-holes outside of a housing. CONSTITUTION: A rotor core member(101) is formed into a thin disc shape. A shaft hole(102) is formed at the center of the rotor core member penetrating the same. Multiple magnet insertion holes(103) are formed in positions near the outer periphery of the rotor core member penetrating the same. A magnet(103a) is inserted into the magnet insertion hole. Multiple through-holes(104) are formed between the magnet insertion hole and the shaft hole in a regular interval. |
