National Stone Sand & Gravel Association members and others allied to the industry are crushing it this “Rocktober” thanks to Single Phase Power Solutions (SPPS) products which power three-phase equipment from single-phase utility service. Their 1-to-3 MicroGrid Power Source™ features a BELLE™ Motor which uses Written-Pole® technology to deliver clean, stable, three-phase power from single-phase utility service. This revolutionary approach eliminates the high fuel and maintenance costs, and the pollution of fossil-fuel-powered Gen-Sets while delivering superior power quality to that of a conventional phase converter. It is far more cost-effective than extending 3-phase power where it is not currently available. Available in 50, 75, and 100 HP configurations, the 1-to-3 MicroGrid Power Source™ is ideal for a broad range of applications in the sand and gravel market.

High Horsepower Motors Which Run-on Single-Phase Service
In addition to the 1-to-3 MicroGrid Power Source™, SPPS manufactures high horsepower single phase BELLE™ motors which use Written-Pole® technology. With ratings from 40 to 100 HP these single-phase electric motors can power aggregate and mining equipment like pumps, conveyors, radial stackers, crushers, and many other products found in aggregate and mining applications.
Motor and Pump Combinations Without The Hassle
The world’s only manufacturer of high horsepower single-phase electric motors can also match their motors to a pump to provide instant productivity. Available from 30 to 100 HP these single phase pump solutions are easily installed by simply connecting to available single-phase utility power – they do not require a phase converter or Variable Frequency Drive (VFD).
Cost Effective and Ongoing Cost Savings
Extending three-phase distribution is expensive, typically between $30K to $110K per mile. Using a 1-to-3 MicroGrid Power Source™ avoids that cost. Utilities often amortize the high cost to extend distribution, charging customers monthly fees whether they use the power or not. Use of a 1-to-3 Power Source™ avoids these charges, which can range from $12K to $60K per year. The highly efficient written-Pole® Motor driving the 1-to-3™ achieves a full load efficiency exceeding 88%, which can reduce energy costs by thousands of dollars each year. Since the 1-to-3™ input runs at unity power factor, there is no power factor penalty, a potentially significant cost avoidance.
Low Maintenance
The 1-to-3™ can replace the diesel or gas engines that are often used as the prime movers for pumps and generator sets. In addition to adding fuel, these engines require significant maintenance and upkeep such as filters, spark plugs, belts, oil changes, and more. The Written-Pole® motor requires very little maintenance in comparison. Air and noise pollution are also reduced, but most importantly reliability is greatly improved with the 1-to-3™.
The 1-to-3™ allows weak single-phase lines to deliver strong three-phase power with excellent voltage regulation and precise 60 Hz frequency. The generator output voltage provides well-balanced three-phase power capable of staring and running large three-phase motors and power quality-sensitive electronic controls. This equipment isolates the application (and the utility) from harmonics that are harmful to sensitive loads.
Efficiency
Written-Pole® motors start using only 1.7x their rated running current. This eliminates the excess voltage sag or “flicker” that can cause problems on distribution lines. The efficiency rating of the motor is 95.5% and the generator efficiency is 93.5%, resulting in an overall efficiency of 89% with 10% electrical isolation. With the 1-to-3 Power Source, ™ customers served by single-phase lines can get high-quality power for three-phase applications. Unlike conventional phase converters, the 1-to-3™ provides true, balanced, three-phase power eliminates disruptive harmonic feedback, is a unity power factor load to the utility, and with an added flywheel, can ride through momentary power interruptions with ease. Single Phase Power Solutions manufactures the world’s only large horsepower single-phase motor. Their patented Written-Pole® technology delivers a robust and reliable solution for agricultural, industrial, municipal, oil & gas, and emerging market applications that needs large horsepower output but only have access to a single-phase power line. They manufacture a full range of Belle Motors™ up to 100 HP as well as their 1-to-3 PowerSource™ that generates three-phase power from a single-phase line.
