Motor rotor iron core support

The utility model relates to a motor rotor iron core support. The iron core support is of a shaft shape. The surface of the iron core support is provided with support ribs axially extending and inclined along the circumferential direction of the iron core support. The motor rotor iron core support which has a simple structure and is easy to carry out not only lowers the punching sheet manufacturing cost, increases the production efficiency but also makes support ribs with corresponding inclination angles processed on itself according to an inclined slot design angle during a processing operation. Design requirements are met. Meanwhile, similar straight slot rotor punching sheet structures can be adopted. When there are defective sheets or deficient sheets, what is needed is only to replace the defective sheets with punching sheets of the same specification. Sheet complementing operations can be very easy.
