Phase Converters: Running a Three-phase Pump on Single-phase

Knowledge / March 9, 2022 / Leave a Comment

Consider this scenario: You go to a flea market, and spot an electric motor that looks similar to the one on the wash-down pump in your barn that is starting to make noise. You know that a new motor would cost way more than what this guy is asking for his so-called slightly-used-but-not-abused motor, so you buy it. You get it home, and in the process of installing it, you find out that it is a three-phase motor, and you only have single-phase power on the farm. You call the utility company, and are told that it will be glad …

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 …

Phase Converter vs. VFDs: Which to Use?

Comparison / March 9, 2022 / Leave a Comment

Performing a voltage conversion will allow your business to take a single-phase system and convert it into a three-phase system. You can facilitate this conversion in one of two main ways — with a phase converter or with a variable frequency drive (VFD). While both options can help you achieve the same result, they each work differently and have distinct advantages and disadvantages. Let’s take a look at each type to help your business decide which one is best for your applications. Phase Converter A phase converter facilitates the conversion by adding another leg to the two single-phase lines. About …
