We hear a lot about two-compartment motors, three-phase motors, or two-phase or three-phase motors. What do we mean by three-phase? What is three-phase electricity? What's the difference with one-phase electricity? If you are unsure of the difference between single phase and three phase AC motors, just keep on reading
Three-phase electricity refers to U, V, and W, that is, three hot wires; a hot wire is called a phase, a three-phase motor between phase and phase is 380V, the voltage between phase and zero line is 220v, and the use of three-phase wire access motor is a three-phase motor. In addition to three-phase motors, there are also single-phase motors, namely, one with a live wire, which is somewhat different from the other. The voltage of single-phase motors is 220v, and the power of the motors is also low due to the low voltage, so the single-phase motors are generally not used for production but only for civil use. The motor used in industrial production is generally a three-phase motor because the industrial motor power is large, generally on the kilowatt, and such a single-phase motor is not up to. If using a single-phase motor to generate several kilowatts of power, you need to add some devices in the middle to complete. Generally, adding a capacitor can, but this will inconvenience industrial production. The basic difference between three-phase and single-phase motors is that they use different power sources. One needs to use three-phase electricity, while the other USES phase electricity.
For GX Fan, 220V&380V, you can choose either voltage.
Summarized as follows:
Single-phase power is:
– Used in most homes and small businesses
– Able to supply ample power for most smaller customers, including homes and small, non-industrial businesses
– Adequate for running motors up to about five horsepower; a single-phase motor draws significantly more current than the equivalent 3-phase motor, making 3-phase power a more efficient choice for industrial applications
3-phase power is:
– Common in large businesses, as well as industry and manufacturing around the globe
– Increasingly popular in power-hungry, high-density data centers
– It is expensive to convert from an existing single-phase installation, but 3-phase allows for smaller, less expensive wiring and lower voltages, making it safer and less expensive to run
– Highly efficient for equipment designed to run on 3-phase
GX Fan can suit both 220V &380V.
