Motor wiring diagram 466703 12 lead single voltage wye start delta run or part winding start revised. Refer to the motor manufacturers data on the motor for wiring diagrams on standard frame ex e ex d etc. Motors with six leads are nearly always single voltage motors. Typically the motor will be a 6 lead or 9 lead motor.
3 schéma de principe pour démarrage à bobinage partiel représentation simpli. 31 prinzipschaltung und motor anschluss kt 400 3 abb. The winding in the motor must be split in order for it to use a part winding start. This method used only a portion usually one half but sometimes two thirds of the motor winding increasing the impedance seen by the power system. 18 nidec motor corporation. These diagrams are current at the time of publication check the wiring diagram supplied with the motor.
Such motors might be dual winding motors in which case you can wire them for a part winding start. Microsoft word 466703 author. Two speed one winding chp ms single voltage. Your first task is to identify how many leads the motor has. Reduced voltage starting methods reduce inrush current and modify acceleration and starting torque characteristics. The part winding starter consists.
