FIXED IRON CORE FOR MOTOR

摘要

PURPOSE:To stabilize motors in quality with the inclination of a bearing holding plates eliminated by placing one upon another punched iron core plates for fixed machine iron cores under specified conditions. CONSTITUTION:Punched iron core plates 2 for fixed machine iron cores 1 are turned in an equal angle smaller than 120 deg. are placed one upon another so that the portions whose horizontal thickness B is large may be formed at the three places separated in about 120 deg.. The core 1 is sandwiched between the bearing holding plates 3 which are placed in front and behind a motor and of which a bearing 4 is fastened to the center. Thereby, the inclination of the bearing holding plates 3 can be eliminated for stabilizing motors in quality.
