The utility model discloses a near-net forming motor powder metallurgy rotor. The rotor comprises rotor body. The rotor body is provided with a center hole and a blade installation straight flute. The rotor body is a component which takes powder metallurgy as a main body. A bottom of the blade installation straight flute adopts fillet transition connection. A working surface of the blade installation straight flute is provided with a wear-resistant composite layer. The rotor of the utility model is manufactured by using a near-net forming powder metallurgy technology. A small amount of machining is needed. A material utilization rate is high and working hours are saved. The working surface of the blade installation straight flute is provided with the wear-resistant composite layer, which can greatly increase wear resistance performance of an eccentric ring. Heat treatment is not needed. The bottom of the blade installation straight flute adopts the fillet transition connection so that stress of the bottom of the blade installation straight flute can be greatly reduced and a service life of the motor rotor can be effectively prolonged.
