480 Volt 3 Phase 2 Speed Motor Wiring Diagram. Constant horsepower 2 speed. Line 2 to motor terminal 2 line 3 to motor terminal 3 leave motor terminals 4 5 6 open and insulated from each other.
Please explain to me. Diagram dd5 two speed motors for all other single phase wiring diagrams refer to the manufacturers data on the motor. High speed higher hp line 1 to motor terminal 6 line 2 to motor terminal 4 line 3 to motor terminal 5 short circuit 1 2 3 neutral this connection is 2 wye.
A three phase motor must be wired based on the diagram on the faceplate.
On a 12 wire motor wired for high voltage i e 480v 10t 11t and 12t must be connected together but not connected to anything else. Diagram dd5 two speed motors for all other single phase wiring diagrams refer to the manufacturers data on the motor. On a 12 wire motor wired for high voltage i e 480v 10t 11t and 12t must be connected together but not connected to anything else. 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.
