Phase Converters vs. Variable Frequency Drive Controller

Comparison / March 9, 2022 / Leave a Comment

Question: What is the difference between a phase converter and a “Variable Frequency Drive” Why would I choose one over the other? Let’s first look at what defines each product… Phase Converters Generally phase converters are divided into three popular methods of control: Static conversion techniques in which the motor is run at less than full efficiency mainly on two of the legs of the three-phase motor. Current is sometimes injected into the third leg with a capacitor or transformer arrangements that provide imperfect phase shift. In these systems the motor must be de-rated. Rotary phase converters constructed from a …

How Do Phase Converters Work?

Knowledge / March 9, 2022 / Leave a Comment

Do you know how factories and homes in isolated areas get supplied with high electric power at a lesser cost? This is due to a device called phase converter, which converts power from a single-phase source into a three-phase power. This ScienceStruck post tells you all about the functioning of this device. Phase converters were invented in the later part of the 1900s. This machine converts power from a single-phase source to three-phase power. There are scenarios wherein applications need three-phase power; however, only a single-phase source exists. These converters are used in such cases to convert the power obtained …

Digital vs. Rotary Phase Converters

Comparison / March 9, 2022 / Leave a Comment

Digital Three-Phase Converters In terms of generated power, these are the top of the heap. It is quite simple how they work. Single-phase motors have two wires which make it turn. Three-phase motors will turn with two legs, but also generate voltage on the third leg that is 60 degrees out of phase with the other two coming from the power company. If you only have single-phase power, you can upgrade to a digital three-phase converter; two phases from the power panel and one generated electronically to be exactly 120 degrees from the other two legs thus giving you the full three …

How Does a Rotary Phase Converter Work?

Knowledge / March 9, 2022 / Leave a Comment

A Rotary Phase Converter is designed to create three-phase power from a single-phase power source. Unlike a Static Phase Converter (that only STARTS a three-phase motor), a Rotary Phase Converter will RUN your equipment continuously and get to its full horsepower potential. The Rotary Phase Converter system is made up of an idler generator and a control panel. Your start capacitors and run capacitors go inside this control panel, as well as any of the switches and relays. By hooking your 3-phase motor to an idler generator and capacitors, you will get a 3-phase power source even though only 1-phase …

Comparing Phase Converter and Variable Frequency Drive (VFD) Applications

Comparison / March 9, 2022 / Leave a Comment

Facilitating voltage conversion, from single phase to three phase, is a common issue in locations where three phase power is unavailable, severely lacking or too costly to introduce from the supply line.  As a solution, businesses may use a device that converts a two-line, single-phase AC source to three-line, three-phase power. The two options that will be explored in this article include phase converter and variable frequency drive (VFD or inverter). Types of Phase Converters A phase converter facilitates three-phase conversion by taking two single-phase lines and supplementing them with an additional leg, resulting in true three-phase power. Phase converters …

Advantages of Rotary Phase Conversion Systems

Benefits / March 9, 2022 / Leave a Comment

All Rotary Phase Conversion Systems have common components: (1) a three phase motor winding that acts as a generator to produce a three phase output from a single phase power source, and (2) a run capacitor section that provides for a more stable current and voltage condition when loads are applied. Some Rotary Phase Converters also have what is known as a “start circuit” which consists of start capacitors, a contactor, and a control relay. The “start circuit” is the most critical link in these Rotary Phase Converters, since if one of these components should fail, the “generator motor” will …

Static vs. Rotary Phase Converters

Comparison / March 9, 2022 / Leave a Comment

Phase converters are devices that aim at transforming a single phase power to three phase electricity. In this article, we discuss why rotary phase converters are preferred over static converters. Phase converters are used to run machinery by converting single phase electricity to three-phase power. There are different types of phase converters. Static, rotary and digital phase converters are the three-phase converters used. However, the most widely used phase converter is the rotary phase converter. Static phase converters have the ability to fire up engines, contrarily, the rotary phase converters are employed to convert single phase power to three-phase power. …
