Part winding motor wiring diagram. The part winding starter consists. Motor wiring diagram 12 lead single voltage wye start delta run or part winding start revised. Inst maint wiringqxd 5032008 1002 am page 6. Your first task is to identify how many leads the motor has. Therefore part winding starters can be used only with motors having stator windings divided into two equal parts with the terminals of each part available for external connection. A portion of the winding either half or two thirds will be connected when the motor is started.
Part winding stop start the part winding starter reduces inrush current by using two different sets of windings in the motor. 18 nidec motor corporation. Reduced voltage starting methods reduce inrush current and modify acceleration and starting torque characteristics. Dual voltage motors have split windings but they can only be started on the lower voltage winding. 3 schéma de principe pour démarrage à bobinage partiel représentation simpli. Two speed one winding vt or ct ms single voltage.
The winding in the motor must be split in order for it to use a part winding start. Motor wiring diagram 466703 12 lead single voltage wye start delta run or part winding start revised. Typical wiring diagrams always use wiring diagram supplied on motor nameplate connection diagrams co leads part winding weg three phase motors volts 12 lead part winding 12 10 11 12 3 l1 l2 12 10 11 64 5 78 9. It is to be used only for voltage recovery and must not be left on the start connection for more than 2 to 3 seconds. In this lesson well examine part winding reduced voltage starters. 182014 nidec motor corporation st.

Such motors might be dual winding motors in which case you can wire them for 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.
31 prinzipschaltung und motor anschluss kt 400 3 abb. Typically the motor will be a 6 lead or 9 lead motor. 3 prinzipschaltbild für teilwicklungs an lauf vereinfachte darstellung für hubkolben verdichter fig. Motors with six leads are nearly always single voltage motors. Refer to the motor manufacturers data on the motor for wiring diagrams on standard frame ex e ex d etc.
