Rotary Phase Converters

Phase converterRotary Phase Converter also refers to a rotary converterphase converterstatic converterphase conversion, or even some of the brand names like rotorphase, phasemaster, phase-a-matic or convert-a-phase. It is a synonymous term for phase conversion. As a generic term converter could mean phasemaster or a rotary converter referring to a product or process. The “heart” of our units has been specifically designed for optimal efficiency and endurance. Featuring our proprietary armature design, they operate cool and quiet.

static converter is simply a bank of capacitors that help energize a 3 phase motor. The static in static converter means that once the system is started the static converter is taken out of the system and not used. A rotary converter or phase converter stays in the electrical system for overload relief.

Voltage Stabilizers

The term voltage stabilizer in the world of a rotary converter refers to a problem associated with rotary converter but not necessarily with a phase converter referring to a static converter. The rotating field of a rotary converter produces a high voltage leg of the three phase system. Some applications need to have that voltage stabilizer. A voltage stabilizer is not necessary with the use of a convert-a-phase rotary converter because of the technology it uses. A phase converter that has a rotating member and used tap-able capacitors can be applied so that the voltage stabilizer is not necessary. The convert-a-phase rotary converter can be extremely functional with less capacitors and the dropping of them can act like a voltage stabilizer.
