You probably already know what phase/voltage you have in your facility, but you shouldn’t take your power for granted. Specifications should always be double-checked before you make a decision on which machine you should buy.
Most of the machines we have in our extensive product line come with Single-Phase or Three-Phase motors and different voltages.
FACT 1: SINGLE-PHASE THREE WIRE
Single-phase electrical service wires usually have a three wire configuration, also known as the Edison system or the center-tapped neutral. This type of single-phase wiring is most commonly found in Canada and the United States. It provides 120 volts for lighting and conventional plug loads and 240 volts for single-phase appliances, such as water heaters and air conditioners.
FACT 2: SINGLE-PHASE THREE WIRE
Three-phase installations provide a smooth and reliable wavelength that many industrial and high-voltage appliances, such as saw mills, air conditioners and refrigeration systems, require to operate. This makes three-phase electrical service popular in commercial and industrial buildings which need to operate voltage-hungry machinery. There are two commonly used three-phase electrical service wiring types: the four-wire Wye and the three-wire Delta. The Wye electrical service is by far the most common in the United States.It has a neutral wire which also allows it to be used for single-phase appliances. The Delta system provides service voltages ranging from 208 to 600 and higher, which explains why it is mostly used in industrial facilities.
Q: What if the machine I am looking for only comes in single-phase or three-phase or some other different voltage?
A: You can use Rotary Phase/Roto Phase Converters and Transformers.
Rotary Phase Converters (to go from Single Phase to Three Phase or vice-versa):
A phase converter is a device that converts electric power provided as single phase to multiple phase or vice-versa.The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service. Phase converters are used where three-phase service is not available from the utility, or is too costly to install due to a remote location. A utility will generally charge a higher fee for a three-phase service because of the extra equipment for transformers and metering and the extra transmission wire.
Transformers (to go from higher voltage to lower voltage or vice-versa):
A transformer is an electrical device that transfers energy between two circuits through electromagnetic induction. A transformer may be used as a safe and efficient voltage converter to change the AC voltage at its input to a higher or lower voltage at its output without changing the frequency. Other uses include current conversion, isolation with or without changing voltage and impedance conversion.
