CHARACTERISTICS
Demand for three-phase power is growing much faster than the availability of three-phase service. Many agricultural, telecommunications, industrial and municipal applications are best powered by three-phase equipment. However, in most rural and remote areas, only single-phase service is available. The 1-to-3™ Power Source solves this problem. Using the revolutionary BELLE Single-Phase Motor™ with Written-Pole® technology, the 1-to-3™ avoids high fuel and maintenance costs, and pollution of fossil-fuel-powered engines. It delivers superior power quality to that of conventional phase converters and is far more cost e�ective than extension of three-phase service for both utilities and their customers, providing bene�ts across a broad spectrum of applications.

SINGLE-PHASE MOTORSLARGE HORSEPOWER
LOW STARTING CURRENT AND HIGH EFFICIENCYWritten-Pole® motors start using less than 2x their rated running current. This eliminates excess voltage sag or “�icker” that can cause problems on distribution lines. The e�ciency rating of the motor is 95.5% and the generator e�ciency is 93.5%, resulting in an overall e�ciency of 89%, with 100% 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 �ywheel, can ride through momentary power interruptions with ease.
PERFORMANCEBELLE Written-Pole® Motor (Input) Driving a Rugged Three-Phase Generator (Output)
• Written-Pole motors are well suited for conversion of single-phase to three-phase power. A Written-Pole single-phase motor can drive a three-phase conventional generator to produce clean, balanced voltage.
• The 1-to-3 (phase converter) can start multiple smaller three-phase motors. The 1-to-3 can start a single motor up to about 65% of its rating and other smaller motors up to its output rating.
• Because of the high load synchronizing capability of the Written-Pole drive motor, a large �ywheel can be added to greatly improve the motor starting capability of the three-phase generator.
