Commutator with mica supporting iron ring structure

The utility model discloses a commutator with a mica supporting iron ring structure. The commutator comprises commutator segments and bakelite powder, the commutator segments are arranged on the outerside of the bakelite powder; adjacent commutator segments are isolated through mica sheets. Two ends of each commutator segment are provided with inner grooves. The commutator is characterized in that inner grooves are formed in the mica sheets, supporting iron rings located in the inner grooves are arranged in the bakelite powder, supporting notches are formed in the two ends of the inner sidesof the mica sheets, the supporting iron rings are embedded into the corresponding supporting notches, and the supporting notches support the supporting iron rings so that the supporting iron rings cannot make contact with the commutator segments. The commutator is simple in structure, and the supporting iron rings are supported by the mica sheets, so that the iron rings and the commutator segments are effectively insulated
