MOTOR

摘要

PURPOSE: A motor is provided to reduce power consumption by connecting the space between the bottom of a disc and a rotor case to the outside of the rotor case and reducing pressure difference and temperature difference. CONSTITUTION: A chucking apparatus(120) mounts a disc. A rotor case has a plurality of air flow channels(150) to circulate air. A disk support member(160) forms an air flow path together with the air flow channels. The disk support member has a circular loop shape. A push part accelerates the air which is flowed in rotating the case.
