![]() A VFD can ONLY run motor loads, its main purposes are motor speed regulation and used as a soft start for motor. This option does provide three-phase power but the quality of the power can vary depending on the manufacturer of the generator.Ī Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Then, with it being an engine that is running to create the power you have to keep up with the standard engine maintenance schedule. With a generator, the operating costs will fluctuate with the cost of oil. What we can look at to evaluate this option is the operating costs of a generator. The price is also reflected by the size of the generator and can range greatly. There are many different sizes available depending on specific needs. Generators are also available in both single-phase and three-phase options. These generators can run on gas or diesel fuel. This option is good if no power is available at the site. If the 3 phase utility is a route you want to choose, it's a good idea to do a true cost analysis to know all of your costs upfront before investing in having it brought in. Moreover, the power quality is not good as expected, the voltage could be either too low or imbalanced across the three legs because most installation sites are far away from substation. This is typically the first option that comes to mind when someone thinks about getting three phase power, however, three phase power from the utility company is not always available in all areas, such as rural, suburb and other remote locations.Įven when 3 phase is available nearby, it can be cost prohibited, the costs of bringing in new service, adding additional transformers and wires can drive costs too much. Here we give you the analysis of each option so you can make a decision on which route is best for you. Each option has its pros but it does come down to what is affordable for you and your situation. These options are through the utility line, a gas or diesel generator, a variable frequency drive (VFD), or through a phase converter. It is true there are many options out there to get three-phase power from single-phase source for your equipment. Thus converting single-phase power to three-phase increasingly become the subject of the calls or emails between the factory and customers, especially 220v single phase to 3 phase 220v or 380v. The general use of 3-phase equipment is increasing on farms and ranches, in home and shops, or in other locations where utility-provided is only single phase and three phase isn't readily available. Payment Methods: T/T, Payoneer, Western Union, Credit CardĪ large number of applications and equipment once considered "industrial" require 3-phase power. ![]()
