Abstract

PURPOSE: To provide a coreless motor wherein air in the hollow part of a rotor is sent out to the ouside thereof by providing a slit in a commutator plate, whereby even when the motor is mounted with its brush side directed downward, the rotor does not slip toward the brush side by the weight of the rotor.
CONSTITUTION: When a rotor A is rotated, air in the inner side of the rotor A is sent out to the outside thereof through an inclined slit 2a formed in the commutator plate 2, and by the blasting operation, the rotor A is pressed against a permanent magnet 4. Even when the motor is mounted with its the brush 11 side directed dawnward, on a cause of said pressing force, the rotor A rotates by the weight of the rotor A without the abutment of an E ring 12 with a bearing 8, thereby to prevent the wear of the brush 10
