PURPOSE: A rotor frame of motor is provided to decrease the deformation generated in the frame to stabilize permanent magnets and enhance workability. CONSTITUTION: A rotor frame(2) of motor comprises a yoke(4) for arraying permanent magnets(3) and a support for fixing the yoke(4) and the permanent magnets(3). The support consists of a fixture surface(10), fixture protrudes(11) and bending protrudes(12). The fixture surface(10) is an internal lower surface of the frame(2). The fixture protrudes(11) are protruded outwardly from the surface(10). The bending protrudes(12) are formed on top end of the frame and bended after the magnets are attached to the surface(10) so that the magnets cannot be detached.
