Claims

[Scope of utility model registration request]

A plurality of T-shaped salient pole pieces are connected radially, a rotor shaft is projected from the upper and lower surfaces of the joint part to form a rotor iron 6, and a coil is wound around each salient pole piece to form the rotor. A rotor for a small DC motor characterized by a magnetic ring fitted around the outer periphery of an iron core.
