The invention relates to a manufacturing method for a rotor of a motor. To manufacture a rotor of the motor, a base component is manufactured for the rotor. The base component is provided with an external cover surface basically in a cylindrical shape and two end surfaces basically in a circular shape; the base component is provided with a plurality of recessed parts extending from one end surface to the other end surface; a cross section of each recessed part is remained the same from one end surface to the other end surface; a plurality of accommodating containers are provided and equipped with a plurality of continuous accommodating grids following each other in a corresponding longitudinal direction; a permanent magnet is introduced to each accommodating grid of each accommodating container from an introducing direction orthorhombic to the longitudinal direction; the permanent magnet introduced to the accommodating grid is fixed; the accommodating container having the accommodating grid containing the permanent magnet is introduced to one recessed part of the base component in a longitudinal direction and fixed there. The invention further relates to a motor having the rotor.
