Balancing Output Voltage of Rotary Converter

Instructions / March 9, 2022 / Leave a Comment

What’s the deal with the output voltage of a 3 phase rotary converter? Why does the output voltage seem to be so inconsistent? What can be done about this? To address this, we first need to understand how the rotary phase converter produces 3 phase electricity. Second, we need to understand why that voltage can be so variable. Finally, we need to look at ways to address this voltage imbalance. How does a Rotary Phase Converter work? In a single phase electrical system, there are 2 hot wires. A 3 phase electrical service adds a 3rd hot wire. A 3 …

How to Run a 3 Phase Motor on Single Phase Power

Instructions / March 9, 2022 / Leave a Comment

Motors usually come in two different types, single or three phase. The number of phases on the motor is determined by how the motor is wound. It is easy to find out how many phases your motor has by looking at one of two factors. First, you can check the motor nameplate data which is usually located on a paper or metal label attached to the side of the motor. Second you can simply look at the number of electrical leads coming out of the motor. If your motor has three black leads and a green lead then it is …

How Do You Balance Voltage in a Rotary Phase Converter?

Instructions / March 9, 2022 / Leave a Comment

For years, many companies have used (and continue to use) the inexpensive method of “stacking” run capacitors in order to get a phase converter started. Those capacitors are not taken out of the circuit once the phase converter is running, which results in extremely high voltage and current imbalance. This condition causes current overloads that will burn out motors that are smaller than what the phase converter was sized for (ie. running a 2HP mill on a 40HP converter). Furthermore, this condition will ultimately cause the phase converter itself to burn out. The justification for continuing to build phase converters …

How to Properly Operate a Three-Phase Motor Using Single-Phase Power?

Instructions / March 9, 2022 / Leave a Comment

There are several methods to operating a three-phase motor using single-phase power to make what would be an otherwise expensive and arduous process a little easier. Three-phase power involves three symmetrical sine waves that are 120 electrical degrees out of phase with one another (See Figure 1). One method of converting single-phase power that worked well for decades was connecting two phases to the incoming 220 V single-phase power and create a “phantom leg” for the third phase by using capacitors to force an offset between the main and auxiliary windings. In this case, the offset is 90 electrical degrees. …

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

Instructions, Knowledge / March 9, 2022 / Leave a Comment

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. …

What Does a Phase Converter Do & Its Types

Comparison, Knowledge / March 7, 2022 / Leave a Comment

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

Instructions, Knowledge / March 9, 2022 / Leave a Comment

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 / March 9, 2022 / Leave a Comment

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 …

Static vs. Rotary Phase Converter-Which to Use?

Comparison, Instructions / March 9, 2022 / Leave a Comment

Phase converters have been around for decades, transforming a single-phase power source into a 3-phase. The two most popular types of phase converters are: Static Phase Converter Rotary Phase Converter Static Phase Converter typically consists of one or several capacitors and a relay switch. Rotary Phase Converter is the same Static Phase Converter only with a small idler motor (or generator) and run-capacitors, that give you a continuous 3-phase power while you use your equipment. The main difference between Static and Rotary Phase Converters is that Static Phase Converter will disconnect itself after your engine has started and you will …
