Enercon E-92

2.35 MW rated power, 92 m rotor. A larger rotor but a lower rating than the E-82 — that choice explains the whole E-92: it was designed to stay in production for more of the year on low- and medium-wind sites.

Why a larger rotor and a smaller rating?

Rated power is the turbine’s ceiling, reached only in strong enough wind. On a weak-wind site the turbine spends most of its time below it. What counts there is not a high ceiling but useful power in light wind.

A larger rotor collects more energy from the same weak wind; a lower rating keeps the generator and power electronics at a point they reach early. The result is an earlier start and a high capacity factor. On a strong-wind site the same choice wastes potential.

Key technical data

Drivetrain and systems

Low speed, high torque

• For the same power, lower speed means higher torque; the annular generator and rotor connections carry that load.

Annular generator and heat

• A turbine that stays in production for long hours in light wind keeps its generator cooling working constantly; clean air paths are a first-order concern.

Yaw

• A larger rotor means a higher moment on the yaw system; lubrication of the adjustment gears and the damping are followed.

Maintenance topics that matter in the field

• Generator cooling air paths and filters.
• Pitch emergency supply and connections.
• Yaw adjustment gears and lubrication.
• Blade surface and root connections: periodic visual checks on a long blade.
