Zusammenfassung:Disclosed is a rotor for a motor for reducing the amount of usage of permanent magnets, in which a rotor structure in which multiple multilayered permanent magnets are embedded has a vacant space in which no permanent magnet is embedded, such that the amount of usage of the permanent magnets is reduced, and an output, torque, and efficiency of the motor are improved by using the space in which no permanent magnet is embedded. The present invention has an effect in that the amount of usage of the permanent magnets is markedly reduced during a process of manufacturing the motor, such that material costs are reduced, working time required to embed the permanent magnets is reduced, working time is greatly reduced, costs are reduced, the number of working processes is reduced, and assembly workability is improved.
