How to Wire a 3 Phase Motor | Hunker

You 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.

A three-phase motor must be wired based on the diagram on the faceplate. The first step is to figure out the voltage of your phases. In the United States, for low voltage motors (below 600v), you can expect either 230v or 460v. That being said, there is a wide range of different motors and what you

Single-phase motors are used to power everything from fans to shop tools to air conditioners. Residential power is usually in the form of 110 to 120 volts or 220 to 240 volts. Wiring a motor for 230 volts is the same as wiring for 220 or 240 volts. Some motors allow both 120-volt and 240-volt wiring by providing a combination of wires for doing so.

All wiring and electrical connections should comply with the National Electrical Code (NEC) and with local codes and practices.

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). L1 to T1, L2 to T2, L3 to T3, T4 to T7, T5 to T8 and T6 ...

Another difference between three-phase wire and single-phase wire concerns where each type of wire is used. Most, if not all, residential homes have single-phase wire installed. All commercial buildings have three-phase wire installed from the power company. Three-phase motors provide more power than a single-phase motor can provide.

Generally, a motor with a nameplate rating of 3ph 230 volts can operate as low as 3ph 207 (+/-10%) system volts. However, if the operating conditions are a heavy load at or near nameplate full load rating, operation at 3-phase 208 volts could result in higher operating amperes, resulting in higher operating temperature.
