How a Variable Frequency Drive Works

Using a variable frequency drive (VFD) can save you on energy costs and consumption. VFDs can also tighten processes, reduce maintenance, increase production, and prolong the life of your equipment. What Is a VFD? A VFD or variable frequency drive is an electronic device used to control an AC induction motor or synchronous motor. A VFD controls the torque, speed, and direction of the motor, smoothly starting and accelerating the motor to the desired speed at a controlled acceleration rate.  Deceleration is also controlled, and braking is available as an option. VFDs allow you to use a single motor for …

Single Phase to Three Phase Conversion

What is phase conversion? A phase converter is a device that produces three-phase electrical power from a single-phase source, allowing the operation of three-phase equipment at a site that only has single-phase electrical service. Why would I need phase conversion? A large number of applications and equipment once considered “industrial” require three-phase power. The general use of three-phase equipment is increasing on farms and ranches, in home wood and metal shops, or in other locations where utility-provided 3-phase isn’t readily available. Even when 3-phase is available nearby, the costs of bringing in new service, adding additional transformers and wire can …

Why Is My Phase Converter Voltage High?

We get asked all the time, “why is the voltage of the one line so much higher than the other two?” All traditional phase converters are high leg delta. This means that when using your meter you will measure 120 volts to ground on two of the three lines, but around 240 volts to ground on the third. This is perfectly normal and will work just fine for most motor loads. Here are some pictures of what you might be seeing. Traditional phase converters create only the 3rd line. The other two lines are left untouched. In a phase converter, the …

Can a VFD Convert Single-Phase Power to Three-Phase?

Using VFDs To Convert Single-Phase To Three-Phase Can a Variable Frequency Drive (VFD) convert my single-phase power supply to run a three-phase motor? Many who call us are looking at the ability to combine phase conversion and speed control in one device and like the potential to save money, hassle, and space. Like most things, however, there is not a simple answer to this question. Single-phase AC power is common in many residential and agricultural settings, although it can also be seen in some industrial locations. It typically will only have two phases (L1 & L2) and possibly a neutral. …

Three-Phase Converters for Metalworking & Welder

Like many other applications, three phase metalworking equipment requires three phase power to operate properly. Industrial metalworking equipment can include both motor and non-motor (resistive and inductive) loads. The voltage-sensitive equipment needs to be operating at full capacity with a balanced output, allowing for different types of loads to be handled with efficiency and precision. ATO phase converters are incredibly versatile, able to power both tiny, lightly-loaded machines and huge, heavily-loaded machines. You’ll only need one phase converter to get the job done. Some of the common metalworking applications that can be powered by a three-phase converter include: Welders Ironworkers …

What Does a Phase Converter Do & Its Types

Why do we need phase converter and what does it do Phase converters are mostly used to convert the single-phase to three-phase. Most of the commercial and industrial electrical equipment need three-phase power, small and large customers such as residential, rural businesses may not have access to a three-phase power or they don’t want to pay for the extra cost of three-phase service. Many locations are still supplied with single-phase power and local power utilities will not allow any suggestion for additional lines to an unserved location. Most of the single-phase users like to use three-phase for their equipment because …

Installation & Application of Phase Converters on Submersible Pump Motors

The phase converter and the four or six inch submersible pump motor have been quite successfully applied to single phase lines for many years. The phase converter and the four or six inch submersible pump motor have been quite successfully applied to single phase lines for many years. It is necessary to recognize the special characteristics of the submersible pump motor and also the characteristics that are encountered whenever this motor is operated from a phase converter. These characteristics must be considered in determining the proper size of phase converter for the submersible pump motor. Submersible motors do not follow …

Knowledge about Phase Converters

Sometimes a woodworker will find himself with a 3-phase tool, but his shop only supplies single phase, 240 volt power. 3-phase motors are common for industrial grade tools, as their efficiency is higher than their single phase counterparts. In order to operate a 3-phase motor on single phase power, we need to make an artificial three phase system. This is accomplished by using a phase converter. The phase converter will artificially generate the third leg of a three phase system from the two poles of a single phase system. This is not a perfect transformation, but it does get the …

Is It Worth Looking into a 3-Phase Converter?

YOU’RE LOOKING FOR MORE RELIABLE 3 PHASE POWER – SHOULD YOU BE LOOKING FOR A 3-PHASE CONVERTER? HERE’S WHAT YOU NEED TO KNOW TO MAKE THAT SWITCH. Three-phase power is awesome. But it is right for you? Look at what a 3-Phase converter can do for you and your business. Most phase converters are used to produce three-phase electric power from a single-phase source. This allows for the operation of three-phase equipment at a site that only has single-phase electrical service. There are many benefits to shifting from single-phase to the more versatile 3-phase. Whether you’re working with a 1-phase shop, or …
