The Peerless turbine is a work of art whose primary inventor is a lifelong kinetic artist who has created massive public art commissions that interact with the wind for over 40 years. In Peerless Wind Systems, Robert Perless works hand-in-hand with engineers who are deeply experienced in turbine evaluation. One reason why the Peerless Wind Systems helix turbine is more than just a pretty face.

Unlike ordinary helix turbines, because of its 270° arc, the rotating motion of the PWS turbine is almost mesmerizing to watch. As it creates power it also creates a beautiful environment.

But the beauty of the Peerless helix turbine is more than skin deep. It is also almost completely silent and self-starting with a cut-in speed as low as 2 mph (our largest competitor has cut-in speeds of 8 mph.) Even in environments such as NYC, where summer winds can drop down as low as 2 or 3 mph, the PWS turbine will continues to operate, although there is not very much energy to convert to electricity at the lowest wind speeds.

Its nearly silent operation ensures low impact to the site area. Regenerative braking controls to continue operation in high wind conditions. PWS turbines were tested in real time during Hurricane Sandy in CT at sustained winds of over 70 mph. Survival speed is 110 mph.

While the PWS turbine efficiently processes airflow, it produces substantially no vibrational effects. The vibrational effects generated during operation of many turbines may be translated throughout the structure of the building, resulting in shaking or even structural cracking. Vibrational effects also produce a great amount of wear upon the turbine itself. Another problem with small-scale turbines is that they process turbulent airflow inefficiently. That is a particular problem in urban environments in which surrounding buildings disrupt airflow, thus increasing turbulence.

While other helical turbines on the market have few design innovations that distinguish them from the original patent filed by Alexander Gorlov in behalf of Northeastern University in the 1990's, the Peerless Wind System turbines represent a true design innovation.

Wind Turbine

In addition to the shape of the turbine, many innovations in design have been incorporated into the PWS wind turbine. The air foil shape has been designed to provide the lift to allow the turbine to spin faster than the wind speed that it pushing it, so that it can extract more energy from the wind than devices of similar size. The leading and trailing edges of the wing blades have been aerodynamically shaped so as to eliminate vortices and allow the turbine to extract more wind energy. The struts that hold the blades in place have their own air foil shape to eliminate drag which slows down a turbine and makes it less efficient. The sum total of the features incorporated into the turbine, results in a very energy efficient design that can utilize more energy from the wind than competitive vertical axis turbines of an equivalent size.

Electric Generator

Rotor/Stator Assembly

Rotor with one set of magnets installed

Stator with potted copper core

Our custom designed electric generator has been created to provide a nearly friction-less environment for our wind turbines, allowing them to drive the generator at very low wind speeds. A rotor, consisting of two rows of very strong permanent magnets, is placed over and rotates freely around a stator containing a thick potted copper core that is created using a proprietary process at PWS. There is little force required to allow the wind to start the rotor spinning around the stator getting the generator operating.

This enormous reduction of friction comes from the incorporation of magnetic levitation technology into the generator, something that has never been done before. In a large scale generator built in the development lab, a two hundred pound rotor applied only one pound of downward force when placed over the stator, as the magenetic levitation eliminated the weight which would otherwise put a lot of friction on the bearings around which the rotor rotates. This also reduces the wear and tear on the bearing, reducing ongoing maintenance to a minimum and allowing PWS to offer a longer warranty on the devices.

The Peerless Wind Systems generator is an air core generator that is easy to assemble and disassemble without any special tools and does not suffer from the magnetic attraction that makes service on other generators a very difficult task.

Our turbines are tested in our own wind tunnel using our wind generator.

The Bella-14 is also a building block for our small wind farms of multiple Bella-14 units connected together in a special mounting shared by the farm to reduce installation costs and combining the power all turbines together.

Note: all turbines come with the Peerless Electric Generator and control electronics to control the amount of electricity output at all wind speeds. The output can charge batteries (DC), be converted to AC (110/220 VAC 50/60Hz) or be feed into the grid to augment other power being used.
