The MDS module is designed for pitch control on wind turbine rotor blades
Integrated hardware and software solution
Integrated safety software
Compact and user-friendly design
Quick and easy installation
In General:The Mita Drive System- MDS - is used for pitch control of wind turbine rotor blades. The MDS is suitable for all types of turbine con-trollers.
Features:The MDS is a hard- and software solution for pitching rotor blades.
The MDS has a detachable, remote-operation seven-seg-ment LCD keypad. It is used to communicate with the drive, set parameters and for monitoring.
The design allows a quick and easy installation.
The very sturdy Drive Sys- tem is placed in the wind turbine hub, and is able to resist severe vibrations and rotations.
Function:The MDS is supplied by the grid for normal operation. A DC back-up system allows emergency operation during grid loss. The MDS controls the motor brake of the pitch motors.
Configuration:Mita-Teknik supplies com-plete pitch solutions includ-ing pitch motors, brake resis-tor encoders, position gauges, and limit switches.
There are 2 principal con- figurations:
a) with hub controller con-trolling the MDS by analog and digital signals.
b) control of the MDS through Modbus communication. (other bus systems can be delivered upon request).
Generally, each MDS drive works independently and is controlled individually. This allows full interchangeability and requires no individual programming.

Plug-and-play solution•
The MDS Pitch MotorsMita-teknik has a long-standing experience with controlling wind turbine pitch systems with our MDS (Mita Drive System). We are offering a motor which is thoroughly tested and prepared for safe and strong control of the blades from the MDS.
the motor is usually mounted on a gearbox at the blade root which allows the heavy blade to be moved without any problems. We can deliver the motor as a raw unfinished product, and you must mount the encoder and all cable connections your-selves. However, we do prefer to deliver the motor with plugs and cables made ready by Mita-teknik. Thus, you will benefit from a plug-and-play solu-tion, and avoid eMC problems due to wrong ca-bling because we have taken care of all the weak and crucial points a drive system could give a mo-tor. We strongly recommend you to choose a com-plete plugable solution from Mita-teknik.
the MDS-motor is a 3 phase asynchronous mo-tor which is ready to function together with the MDS (Mita Drive System). it has a forced ventila-tion integrated depending on the application and motor size. the motor is prepared for Mita-teknik incremental encoder which is a very strong and well-tested solution.
the motor has a DC brake controlled by the MDS with battery backup. the motors have an inte-grated PtC temperature measurement (thermis-tor) allowing the MDS to monitor the motor tem-perature. the motor has a temperature bimetallic control of forced ventilation which allows the mo-tor to run with full performance even by low RPM for a long time. Mita-teknik uses standard 4-pole motors with rated full speed motors to 1440 RPM at 50 Hz. the motor can run double speed by 100 Hz, but the torque power will only be half on the motor shaft. For a short time it can deliver much more power than the rated power (more than 200%). the motor torque curve will tilt after 2 x nominal torque (Ma/Mn > 2).
All the motor features are designed to fit the MDS pitch system. Please try our complete solution and enjoy the performance.
