SPPS introduces single-phase electric motor

Single Phase Power Solutions (SPPS), Cincinnati, has introduced a 100-horsepower single-phase electric motor. Belle Motors use Written-Pole technology to “minimize voltage sags and flicker on long single-phase distribution lines,” SPPS says.

Ideal for industrial applications in areas where three-phase power is not readily available or cost-effective, the technology eliminates the need for phase converters or complex variable frequency drive installations, according to a SPPS release.

Featuring an enclosed fan-cooled design in a cast iron frame, the design is suitable for indoor or outdoor installation in some of the most demanding environments and applications. Rated as a 460-volt, 1,800-rpm electric motor, SPPS says the innovative design delivers 95.5 percent efficiency at rated load with a near-unity power factor. The NEMA 449T frame motor weighs about 2,700 pounds and draws just 170 amps at full load.

The motor windings are fabricated using high-grade copper and Class H insulation materials similar to materials used in three-phase electric motors.

Belle Motors, available in 30- to 100-horsepower ratings, are ideal for industrial, agricultural, mining, municipal and oil and gas applications such as pumps, compressors, injection wells, as well as blowers, fans, dryers, water and wastewater processing.

Belle Motors features include low starting current, energy efficiency, instantaneous restart and a high inertia starting capability.
