Part winding motor wiring diagram. Refer to the motor manufacturers data on the motor for wiring diagrams on standard frame ex e ex d etc. You can connect them for a delta start or a wye start. 182014 nidec motor corporation st. Part winding stop start the part winding starter reduces inrush current by using two different sets of windings in the motor. 3 scematic wiring diagram for part winding simplified sketch for reci procating compressors fig. Dual voltage motors have split windings but they can only be started on the lower voltage winding.
In this lesson well examine part winding reduced voltage starters. 31 prinzipschaltung und motor anschluss kt 400 3 abb. 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. Motor wiring diagram 466703 12 lead single voltage wye start delta run or part winding start revised. The winding in the motor must be split in order for it to use a part winding start. 18 nidec motor corporation.
Your first task is to identify how many leads the motor has. 3 schéma de principe pour démarrage à bobinage partiel représentation simpli. A portion of the winding either half or two thirds will be connected when the motor is started. 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. Two speed one winding chp ms single voltage. The part winding starter consists.
Typically the motor will be a 6 lead or 9 lead motor. 182014 11406 pm. Two speed one winding vt or ct ms single voltage. 3 prinzipschaltbild für teilwicklungs an lauf vereinfachte darstellung für hubkolben verdichter fig. 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. Such motors might be dual winding motors in which case you can wire them for a part winding start.
Reduced voltage starting methods reduce inrush current and modify acceleration and starting torque characteristics. 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. Motor wiring diagram 12 lead single voltage wye start delta run or part winding start revised. Microsoft word 466703 author. These diagrams are current at the time of publication check the wiring diagram supplied with the motor.
