Pitch systems

ATECH - your partner for customized pitch systems

ATECH is your partner for individual, tailor-made, customer-specific pitch systems and pitch products in the low voltage range for both onshore and offshore wind turbines from 200kW to 6MW.

Our pitch solutions are already used worldwide and have proven their worth for many years. Due to the optimal adaptation to the current wind speed and the torque of the drive shaft, we guarantee a highly efficient reliable solution for your wind turbines. They are designed to meet the exact customer requirements. Our ATECH pitch system guarantees a long service life and an extremely low maintenance effort

  • More than 24,000 turbines are in operation worldwide
  • Low maintenance
  • Partner of the world’s leading wind turbine manufacturers
  • Years of experience

 

 

The ATECH pitch system for low-voltage, regulates the angle of the blades of wind turbines, thus guaranteeing an optimal energy yield and safe operation of the wind turbine at all times. Each pitch system can be individually adapted to your requirements. Even in case of strong winds, extreme climatic conditions or in offshore regions – we will find an optimal solution for your application.

The ATECH pitch system consists of the following main components:

  • Pitch Inverter
  • Power Supply
  • Backup capacitator system (Low voltage Design)
  • SPS
  • Power surge protection
  • DC/DC-converter

ACE-2 NG / BLE-2 NG

With the ACE-2 NG / BLE-2 NG (NEW GENERATION), ZAPI brings its industry-leading experience in brushless control technology to offer a flexible and robust product. These models are designed to drive asynchronous or synchronous motors.

Depending on the application, these models can handle the majority of vehicle control via the configurable integrated I/O.

The field upgradeable firmware can be fully customised to OEM specifications or a CANopen solution can be supplied to provide extensive flexibility.

The ACE-2 NG is compatible for operation with asynchronous motor technologies with incremental encoder signals. The BLE-2 NG is compatible for operation with synchronous motor technologies with SIN/COS or 3 x Hall sensor or six-step sensor or resolver.

This ZAPI motor controller is equipped with CAN bus communication, flash programming and the patented ZAPI algorithm as standard and is compatible with the standard diagnostic tool from ZAPI.
