LTI Motion presented its new PitchOne for the first time at WindEnergy Hamburg from 25 to 28 September 2018. The 5th generation of dedicated pitch servo drives is specially designed for the requirements of the 3 to 4 MW class of wind turbines. With its very compact design and passive cooling, the PitchOne is convincing at first glance. In size 20, it delivers up to 45 kW of power for safe emergency blade travel.
In product development, the aim was to combine the most technologically sophisticated innovations with a cost-efficient design. Thanks to the high level of function integration, the pitch system can be designed more cost-effectively overall, since fewer individual components and less wiring are required. With remote update capability via OPC-UA and its modular and service-friendly design, PitchOne also significantly reduces OMS costs. Further significant cost savings at turbine level can be achieved through a series of newly implemented safety functions and the TÜV-certified emergency run with Performance Level E.
Thanks to its wide voltage tolerance of 140 %, the new PitchOne meets all known HVRT grid connection requirements. The internal DC/DC converter also provides a high DC link voltage during LVRT load conditions, allowing efficient dimensioning of the motor and backup energy storage capacity. The optional PLC programming via CODESYS offers flexibility and know-how protection for your application.
With the PitchOne, LTI Motion, based on 20 years of experience in the field of pitch drives, once again presents a product that sets new standards.
