12 lead part winding motor. 1 8 2014 1 14 06 pm. Motor wiring diagram 12 lead single voltage wye start delta run or part winding start revised. There are also some distributors or oem s who like to stock dual voltage wye start delta run motors such as 3 50 220 440.

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 12 l1 l2 12 10 11 64 5 l1 l2 starting type. If leads are numbered 1 to 12 the motor is typically rated for two voltages and could be used with a wye delta starter at either voltage or a part winding starter for low voltage only. The 12 leads represent six different windings.

It can be connected two wye to start and two delta for run operating on the two delta voltage. Twelve lead induction motors will almost always run connected delta. Delta run special feature.

Motor wiring diagram 466703 12 lead single voltage wye start delta run or part winding start revised. See the figure below. For the higher voltage pairs of windings are connected in series then the three resulting pairs are connected into a delta configuration to tie to.

It can also be connected one wye start and one delta run operating on the one delta voltage. This type of motor requires twelve leads and is connected parallel wye delta for low voltage and series wye delta for high voltage. 3 phase motor wiring diagram 12 leads 3 phase 6 lead motor wiring diagram elegant awesome 12 lead 3 phase motor wiring diagram electrical.

12 lead dual voltage wye start delta run both voltages or 6 lead single voltage wye start delta run. Units rated for single voltage may have 12 leads and be suitable for wye delta or part winding starts. Motors designed by us motors for wye start delta run may also be used for across the line starting using only the delta connection.
