Simply effective
Simplicity and efficiency. The anatomy of a LEITWIND wind turbine:
The LEITWIND-patented direct drive is the core of the entire system. The connection between the hub and the generator eliminates the gearbox, an essential part of traditional wind turbines. The system reduces the number of rotating parts, rotation speed, and friction. This solution increases reliability while reducing wear and maintenance costs. In its 20-year lifespan, a LEITWIND generator performs the same number of rotations that traditional ones perform in a few months. Reducing the number of rotating parts and, thus, friction results in higher efficiency. Therefore, LEITWIND wind turbines are also suitable for less windy areas.
Modular Design for excellent production at reduced costs
LEITWIND wind turbines’ design is based on a modular concept that reduces transport costs, making installation possible even in places that are difficult to access. In LEITWIND wind turbines, the synchronous generator is part of the bearing structure, making the entire system cost-effective.
The transformer and electronic parts are integrated into the tower base, making external transformer stations obsolete.

Designed to reduce maintenance costs
The innovative frame ensures safety and easy access to all parts that need maintenance. In addition, the modular design allows for quick replacement of the various parts without using a crane or having to dismantle the generator.
A generator that optimizes energy production
The multi-pole synchronous generator with permanent magnets helps make the most out of the wind. Whatever results from the induction process is converted into energy.
Permanent magnets improve energy production without exciting the generator’s coils. This asset ensures significant advantages, especially in the partial load range.

Yaw and pitch control System for top performance
The LEITWIND control system analyses performance automatically and allows for a variable number of revolutions and progressive pitch control. This way, we can optimise production under any condition. The mechanical brake and the yaw system consist of hydraulically- and electrically-operated parts. The electrically-operated brake opens only when the yaw motor is running. The hydraulically-operated part consists of a primary control system and mechanical brakes.
