When a motors power supply is brought in from three wires instead of just one with the power delivery cycling through each of these in sequence hence the a part of ac it permits an effective power level that is 3 times higher about 1728 times higher than a. Elektrim motors designs and manufactures ac nema and metric iec motors up to 6300 hp in. 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.
Collection of 3 phase motor wiring diagram 12 leads. It reveals the components of the circuit as simplified shapes and the power as well as signal connections between the gadgets. Three phase wiring diagrams always use wiring diagram supplied on motor nameplate.
