PURPOSE: A rotor for disc type motor is provided to reduce a windage loss or a friction loss from a high speed rotation by strengthening a structural intensity. CONSTITUTION: In a rotor for disc type motor, a stator disc(600) having a plurality winding coil(61) inside, couples in a motor case(200) at regular intervals. A rotor disc(700) is inserted in the intervals of the stator disc(600), and fixed to a motor axis(400) inserted in the middle of the rotor disc(700). The rotor disc(700) includes a disc(70) having a regular thickness and area. A plurality of permanent magnets(71) are coupled in the inside of the disc(70) to correspond with a winding coil(61) coupled with the stator disc(600). A ring-formed supporting member(72) is inserted to enclose the disc(70) and reinforces and supports a centrifugal force of the permanent magnets(71) when the disc(70) is rotated.
