PitchMaster II+ Especially for challenging operating conditions

The extremely robust PitchMaster II+ pitch drives were specially developed for the rough operating conditions in wind turbines rotor hubs. PitchMaster II+ drives make the cabinet design easier with the high level of functional integration and also considerably reduce the pitch control cabinets’ volume and wiring. The certification for your wind turbine will be simplified due to TÜV-certified functional safety.

PitchMaster II+ products are designed for the rough environmental conditions in a wind turbine’s rotating hub. They feature the following product properties:

  • High overload capacity, available in two sizes:
    • E40 with 40 A nominal and 100 A peak
    • L60 with 60 A nominal and 200 A peak
  • AC and DC motor support: The software supports the control of synchronous, asynchronous and DC motors
  • Integrated GL2010-compliant monitoring of the emergency power without additional converters
  • TÜV-Rheinland certificate for emergency operation safety function with performance level d in accordance with EN ISO 13849-1
  • Preconfigured and application-specific software functions simplify and speed up commissioning
  • Service diagnosis and remote maintenance by Ethernet: PitchMaster II+ logs configuration changes and critical external events

We are back - with new vital energy! In the 5th generation of high-performance and compact pitch solutions.

The global wind turbine market is changing at fast pace. Only strong innovators are able to satisfy their customers in times of price pressure and digitisation.

LTI Motion has been satisfying its customers with servo drives for 45 years. We manufacture dedicated wind pitch drives for more than 20 years. Onshore and offshore.

High availability Suitable for installation at operating heights up to 3,000 m

Electrical pitch systems with PitchMaster II+ models are suitable for installation at operation heights up to 3,000 m and internal controls cabinet temperatures from -40 to +70 °C. This device platform’s innovative product features include an intelligent pre-charge DC link unit that which protects the slip ring from too high charging currents and allows for optimised, safe fault ride through operation (LVRT, HVRT).

Easy servicing Reduced number of components

PitchMaster II+ drives include a PWM high voltage brake driver to directly control the motor brake. Like the integrated backup power charger, this reduces the number of components in the control cabinet and maximises availability and easy servicing.


Pitchmotor

PitchMotors For challenging use in wind turbines

The pitchmotors are adapted for challenging use in wind turbines and tested under extreme climate conditions. The AC synchronous motors are distinguished by their high power density and field weakening capacity.

Your benefits at a glance:

  • Suitable for onshore/offshore operation thanks to corrosion protection class C5-M, and special inner coating
  • Long life and low maintenance thanks to integrated wear-free permanent magnet brake and robust resolver
