1-to-3 Power SourceT Generates 3-Phase Power from Single Phase Input Unique Technology available in 50, 75 and 100 HP Configurations

(Cincinnati, OH) – Single Phase Power Solutions introduces the 1-to-3 Power SourceT features a BELLET Motor which uses Written-PoleR technology to deliver 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 Power SourceT is ideal for a broad range of industries and applications, including mining, agriculture, and commercial and industrial sites where three phase power is not available, and more.

A Written-PoleR single-phase motor can drive a three-phase conventional generator to produce clean, balanced voltage.  The proven converter circuit can start multiple smaller 3-phase motors.  The 1-to-3 Power SourceT can start a single motor up to about 50% of tis rating, and other smaller motors up to its output rating, thus providing flexibility and cost savings.

Because of the high load synchronizing capability of the Written-PoleR drive motor, a large flywheel can be added to greatly improve the motor starting capacity of the three-phase generator.

Cost Effective and Ongoing Cost Savings

Extending three-phase distribution is expensive, typically between $30K to $110K per mile.  Using a 1-to-3 Power SourceT 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 SourceT avoids these charges, which can range from $12K to $60K per year. The highly efficient written-PoleR Motor driving the 1-to-3T achieves a full load efficiency exceeding 88%, which can reduce energy costs by thousands of dollars each year.  Since the 1-to-3T input runs at unity power factor, there is no power factor penalty, a potentially significant cost avoidance.

Low Maintenance

The 1-to-3T 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-PoleR motor requires very little maintenance in comparison.  Aire and noise pollution are also reduced, but most importantly reliability is greatly improved with the 1-to-3T.

Power Quality

The 1-to-3T allows weak single-phase lines to deliver strong thre-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-PoleR 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 SourceT customers served by single phase lines can get high-quality power for three-phase applications.  Unlike conventional phase converters, the 1-to-3T 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-PoleR technology delivers a robust and reliable solution for agricultural, industrial, municipal, oil & gas, and emerging market application that need large horsepower output but only have access to a single-phase power line.  They manufacture a full
range of Belle MotorsT up to 100 HP as well as their 1-to-3 PowerSourceT that generates three-phase power from a single-phase line.  For additional information visit www.sppowersolutions.com, or write sales@sppowersolutions.com, or Single Phase Power Solutions, LLC, 5460 Muddy Creek Road, Cincinnati, OH,  45238, or call (877) 430-5634.
