SPPS has introduced its 100-hp single-phase electric motor. The Belle Single-Phase Motor uses 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. It is ideal for powering equipment like pumps, compressors, and other equipment typically found in industrial, municipal, agricultural, mining and oil & gas installations.
The BELLE Motor™ utilizes patented Written-Pole® technology to deliver large-horsepower output from 230v or 460v single-phase lines. This revolutionary motor system allows operators to drive a variety of applications without the need for a Variable Frequency Drive or Phase Converter and without the prospect of costly 3-phase line installation.
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.
Written-Pole® technology is a revolutionary, yet fundamentally simple approach to enhancing the performance of electric motors and generators. The application of Written-Pole® technology frees engineers from one of the most basic constraints faced by designers of conventional induction and synchronous machines. Unlike conventional designs, where the magnetic poles are fixed by the geometry of the rotor cage and stator windings, Written-Pole® machines incorporate a proprietary concept that optimizes the magnetic geometry of the rotor for peak performance as the operating speed of the machine varies.
BELLE™ Motors are up to 60% more efficient than diesel engines. With a near unity power factor, operating efficiencies of 95.5%, and a running speed of true 1800 rpms, our motors outperform diesel engines for most applications. Utilizing our patented Written-Pole® technology, we are able to produce starting currents of less than 2x the running current (typical induction motors require 6x the running current for starting) allowing for a utility-friendly startup on the power line as well as making our motors more cost efficient due to our low startup requirements.
Low Starting Current
BELLE™ Written-Pole® single-phase motors exhibit starting current requirements comparable to conventional single-phase motors one-fourth their size. This feature reduces annoying voltage sags when starting without requiring users to install complex reduced voltage starters.
Their low starting current dramatically enhances the capability of a single-phase service to support much larger motors than previously thought possible, eliminating the need for costly three-phase service extensions.
Three-Phase Performance using Single-Phase Power
While their low starting current and high operating efficiency eliminate the need for three-phase power in many applications, BELLE™ Written-Pole ® single-phase motors also compare favorably to premium efficiency three-phase motors in many areas. In fact, BELLE™ Written- Pole® single-phase motors often go beyond three-phase performance, enhancing the system’s performance by reducing starting current requirements to levels below that of three-phase motors and eliminating the need for reactive power through their unity power factor operation.
Oil and gas motors that can stand up to the harshest conditions
The oil and gas undustry places electric motors in some of the harshest conditions around. In areas where only single-phase power is available the BELLE Motor from Single Phase Power Solutions provides a large horsepower solution that is reliable, tough and needs very little maintenance. From the frigid enviroments of the oil sands to injection sites in the extreme heat of texas, electric motors are a critial part of the operation of these facilities. The BELLE Motor from Single Phase Power Solutions are more than up to the task.
Complete Solutions for Compression and Pumping: The BELLE™ motor from Single Phase Power Solutions provides a large horsepower solution for oil and gas applications that only have access to single-phase power. Whether it is one of our high-speed, gearless permanent magnet motors for a single application or our innovative 1-to-3 Microgrid Power Source™ capable of running multiple 3-phase motors on a single-phase line while eliminating the need for a variable-frequency drive (VFD), our solutions are designed to deliver maximum efficiency and reliability.
