12 Lead High Voltage Motor Wiring. I need wiring diagrams for 3 phase 240480v 12 lead 75 hp ac industrial motors. Typical connection diagrams three phase motors y start delta.
12 lead dual voltage wye start delta run both voltages or 6 lead single voltage wye start delta run. You would wire it high voltage if you were supplying 460v. And whether a 9 lead motor is wired wye or delta at the factory has no effect on whether your supply is wye delta.
Across the line starting on the delta run connection where the full winding is energized at either high or low voltage.
12 leads 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. Furnished upon request only. A 12 lead wye start delta run motor has the ability to meet several starting criteria such as. 12 leads 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.
