Connecting Motors For A Change Of Voltage
Wiring a 12 lead motor. I need wiring diagrams for 3 phase 240480v 12 lead 75 hp ac industrial motors. Hold the bare ends of the conductors together and twist on a wire nut. Electrical motors 12 lead dual voltage wye startdelta run both voltages or 6 lead single voltage wye startdelta run motors designed by us motors for wye start delta run may also be used for across the line starting using only the delta connection. The 3 phase ac source line voltage l1 is connected to the motor terminals 1 12 line voltage l2 is connected to the motor. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6. Electric motor wire marking connections.
Motor wiring diagram us. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. Always use wiring diagram supplied on motor nameplate colored leads are only applicable on the new rolled steel motor lines single phase wiring diagrams. 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. Symbols that represent the components in the circuit and lines that represent the. The other 9 wires would be connected as in a 9 wire motor note in a 9 wire motor the equivalent of t10 t11 and t12 are internally connected together.
Always use wiring diagram supplied on motor nameplate. W2 cj2 ui vi wi w2 cj2 ui vi wi a cow voltage y high voltage z t4 til t12 10 til t4 t5. Wire a three phase motor in either a wye configuration or a delta configuration in high or low voltage using a nine lead set up. Three phase see below single voltage. Motor wiring diagram 12 lead single voltage wye start delta run or part winding start revised. On a 12 wire motor wired for high voltage ie 480v 10t 11t and 12t must be connected together but not connected to anything else.
Wiring diagrams are made up of two things. Phase a brown wire motor lead t1 phase b yellow wire motor lead t2 phase c orange. A wiring diagram is a form of schematic which uses abstract pictorial symbols to exhibit each of the interconnections of components inside a system. For specific leeson motor connections go to their website and input the leeson catalog in the review box you will find connection data dimensions name plate data etc. If the motor runs backwards swap any two phases to reverse the rotation like this. 3 phase motor wiring diagram 12 leads whats wiring diagram.
