Abstract
The present invention relates to a brushless type motor and to rotor for brushless type motor with surface magnets. The rotor having an axial extension in which is inserted the shaft having the axial extension a height greater than that of the stator package, and the axial extension also characterized by having a radial extension into the lower base of the magnets, the radial extension having an external radius greater than or equal to the radius of the axial extension, but less than or equal to the external radius of the magnets. The axial and radial extensions being used for fixing the shaft, increasing the moment of inertia, increasing the magnetic flux generated by the magnets and also serving as a base for the assembly of the magnets.
