[Ссылки могут видеть только зарегистрированные пользователи] The Pivoted Panel Wind Turbine will tap its power from the perimeter rather than the axis. In doing so and when implemented, this system will eliminate or greatly reduce the need for a step-up gear.

An animation of a vertical axis wind turbine that I created in 3DS Max. These things are real, and are supposed to be more efficient than the standard three-blade windmill-like turbines. [Ссылки могут видеть только зарегистрированные пользователи]

[Ссылки могут видеть только зарегистрированные пользователи] Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates.

[Ссылки могут видеть только зарегистрированные пользователи] We Make The Worlds Largest PMA's

SLOW TURNING - HIGH POWER!

LOW RPM Permanent Magnet Alternators. (Very rare)

We ONLY custom make this PMA line so it
takes about 3 months to build our really big ones.

We start out with AC motors and totally gut them and install magnets and windings!

These are very rare 135 Pole ultra slow turning, super slow speed motors.

The DC units are Single phase and the AC units are Three phase.
What makes these PMA's SO special is that some develop full
power at only 140 RPM! Perfect for large direct drive props.

Permanent magnets frameless [Ссылки могут видеть только зарегистрированные пользователи]
alternators
for Direct Drive

The range of STK Permanent Magnet frameless alternators addresses the applications of Wind Turbine generators in low and medium power needing the highest power-to-weight ratio in Direct Drive without gear for matching cost-effective solutions.

Each component of a wind turbine generator and wind turbine alternator requires maximum strength and precision in order to ensure perfect control over the blades.

Main characteristics of wind turbine alternators

# Rated power from 200 W up to 99 kW depending on size and rated speeds.
# Rated speeds from 80 RPM up to 1500 RPM.
# Six overall diameters from 145 mm up to 795 mm.
# Internal diameter from 56 mm up to 630 mm.
# Various available voltages up to 500 Vac.

Assets of wind turbine alternators

# No speed multiplier, no gear
# No maintenance
