Abstract

PURPOSE: To provide a commutator which can be readily produced with small-sized rigidity by punching one conductive plate into a governor and a commutator piece, extruding then a commutator conductor, and finally cutting the base end of the commutator piece.
CONSTITUTION: A conductive arm 2a and a supporting conductive piece 2b are buried in an insulating plate 3 in a manner that the end 2c is merely projected from the edge of the plate 3. A hole la is perforated at the center of a cylinder 1 at the center of the plate 3. Supporting posts 4, 5 are formed by bending the end of the piece 2b, a spring retainer 4a is fixed to the post 4, and a spring piece 5a is fixed to the post 5. When the plate 3 is rotated with the rotary shaft, the piece 5a in contact with the retainer 4a is separated by the centrifugal force of the weight 5b. The pieces 4a and 5a are mounted after molding. After the piece 2 and the governor portion 5 are punched from one conductive plate, the piece 2 is extruded, and finally cut at the connected portion of the commutator piece in the vicinity of the center.
