3 Phase Loads
One of the most common class of 3 phase load is the 3 phase electric motor. A 3 phase induction motor has a simple design, inherently high starting torque, and high efficiency. Such motors are applied in industry for 3 phase pumps, fans, blowers, compressors, conveyor drives, and many other types of motor-driven equipment. There are a lot of benefits to using a 3 phase motor over a 1 phase electric motor.  A 3 phase motor is more compact and less costly than a 1-phase motor of the same voltage class and rating; also 1-phase AC motors above 10 HP (7.5 kW) are not as efficient and thus not usually manufactured.   Large air conditioning equipment (for example, most air conditioning units above 2.5 tons (8.8 kW) cooling capacity) use 3 phase motors for reasons of economy and efficiency.  Read more about 3 phase power loads below.

3 Phase Loads
Resistance heating loads such as electric boilers or space heating may be connected to 3 phase systems. Electric lighting may also be similarly connected. These types of loads do not require the revolving magnetic field characteristic of 3 phase motors but take advantage of the higher voltage and power level usually associated with 3 phase distribution.

Large rectifier systems may have 3 phase inputs; the resulting DC current is easier to filter (smooth) than the output of a single-phase rectifier. Such 3 phase rectifiers may be used for battery charging, electrolysis processes such as aluminum production, or for operation of DC motors.

Another interesting example of a 3 phase load is the electric arc furnace used in steel making and in refining of ores.

In much of Europe stoves are designed to allow for a 3 phase feed. Usually the individual heating units are connected between phase and neutral to allow for connection to a 1 phase supply where this is all that is available.

3 Phase Power Generators
There are many options for 3 phase power generators.  These range from small portable 3 phase generators to large industrial diesel generators.  There are many different fuel options to choose from and your application will help determine what is best for your companies need.  Propane generators and diesel generators are the most popular because of the availability of these common fuels.

3 Phase Loads from 3 Phase Power Generated on 1 Phase Power
There are many places and instances where 1 phase power is all that is available, or where the power company wants to charge tens, or even hundreds of thousands of dollars to install and supply 3 phase power.  When this is the case a quality 3 phase generating phase converter can be run on 1 phase to power 3 phase equipment of any type.  Click here to read more about powering 3 phase loads with 3 phase power generated from 1 phase power.

3 Phase Converters
Often the advantages of 3 phase motors, and other 3 phase equipment, make it smart and easily worthwhile to convert single-phase power to generate 3 phase with a Rotary Phase Converter. Small and large customers, such as residential, rural businesses, or farm properties may not have access to a 3 phase supply, or may not want to pay for the extra cost of a 3 phase service, but may still wish to use 3 phase equipment. Such 3 phase converters may also allow the frequency (see also frequency converters) to be varied allowing for different equipment frequency requirements (50Hz, 60Hz, 400Hz, etc.) and also for motor speed control (VFDs).  Some locomotives are driven by 3-phase motors with 3 phase converters converted from the incoming supply of either DC or 1 phase AC.   The two main types of 1 phase to 3 phase converters are Rotary Phase Converters and Static Phase Converters.  Click here to read more about 3 phase converters.
