Latest Patents
Yoshida's latest patents include a method of manufacturing flat-type commutators. This innovative design secures the fixing of carbon (graphite) commutator pieces to metal plates with terminals for connecting windings and electrically insulating support. The manufacturing process is designed to be simple and cost-effective. The flat-type commutator features a brush slide-contact surface that is perpendicular to the rotor's axial direction. A plurality of commutator pieces, isolated by slits, are directly fixed to an electrically insulating support. Additionally, a metal plate for connecting the commutator pieces is affixed to the outer peripheral surface of each commutator piece, which runs parallel to the rotor's axial direction. This method allows for simultaneous formation and fixing of the commutator pieces, enhancing efficiency in production.
