Large-hp, single-phase motor is ideal for industrial use
Single Phase Power Solutions
The Belle Single-Phase Motor (photo) is said to be the world’s first 100-hp single-phase electric motor. It uses patented Written-Pole technology to deliver a 100-hp single-phase motor that is compatible with readily available single-phase utility services. This eliminates the need for phase converters or complex variable-frequency drive installations, and minimizes voltage sags and flicker on long, single-phase distribution lines. It is ideal for industrial applications where three-phase power is not readily available or cost-effective, to power equipment such as pumps, compressors, injection wells, blowers, fans, dryers water- and wastewater-processing equipment and more. Rated as a 100-hp, 460-V, 1,800-rpm electric motor, it is suitable for indoor or outdoor installation. The NEMA 449T frame motor weighs about 2,700 lb and draws just 170 A at full load, says the company. In addition to a full range of Belle Motors from 30 to 100 hp, the company also offers a 1–to–3 MicroGrid solution that generates clean, high-quality, three-phase power from a single-phase line for packaged equipment requiring a three-phase power source. — Single Phase Power Solutions, Cincinnati, Ohio
