Focusing on the areas of industrial automation, energy saving and wind industry, Lafert is the preferred partner for many world leaders in the wind industry with motors installed in more than 20,000 nacelles on turbines worldwide.

The primary benefit of installing Lafert motors is a reduction in life cycle costs. Lafert has a strong focus on quality and reliability, which – combined with continuous improvements in motor efficiencies – puts Lafert in a strong position as the partner of choice.

The company has identified several applications where lifetime reliability, weight, size and efficiency can be key factors for a motor within the wind industry. These may include yaw and pitch drives, hydraulics, pumps, ventilation and lifts for service or personnel.

For pump and ventilation applications, Lafert has particular strengths in offering AC motor and PM motor designs alike. A strong AC motor range has the ability to meet the needs of specific applications through customisation. In general, PM motors are half the weight of AC motors of a similar power/size. If IEC dimension housings are required, PM motors for IE4 or IE5 are available.

In a wind turbine, there are numerous pump and ventilation applications. Pumps secure the energy-efficient flow of fluids, fans in ventilation systems cool equipment, and both are critical for quality and require robust motor designs adapted to the applications.

Lafert motors are designed for the harsh environments found in hubs or nacelles. It takes into consideration possible vibrations, temperature and environmental conditions, and provides corrosion protection, which is now required in offshore installations.
