How to Wire a 3 Phase Motor | Hunker
Jul 17, 2017You must match the wiring to the both the motor nameplate specification and the power you are supplied with. If you have 230-volt three-phase, you have to wire the motor in the lower voltage configuration. Likewise with 460 volts, you have to wire the motor for the higher voltage configuration.
Three Phase Transformer Connections and Basics
Where: V L is the line-to-line voltage, and V P is the phase-to-neutral voltage. A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase. To make the transformer connections compatible with three-phase supplies we need to connect them together in a particular way to form a Three Phase Transformer Configuration.
