- All our converters allow sensorless control of turbo compressors and motors up to the highest speeds.
- The solution from one single source guarantees optimal compatibility of the converters and the turbo compressors and motors, thus minimizing losses in the turbo compressor or motor and ensuring high converter efficiency and a smooth startup process.
- Matching the modulation and control to our own motors and turbo compressors, your permanent-magnet synchronous machine (PMSM) or your brushless DC motor (BLDC) guarantees maximum performance in the converter and minimal losses in the motor, especially in the rotor.
- The proprietary sensorless control strategies enable speed control without encoders or Hall sensors.
- The converter software makes it possible to diagnose the compressor and monitor the condition of the gas bearing as well as providing various application-specific functions.
