Sensorless control – from standstill to 1 million rpm. All of our converters allow sensorless control of permanent magnetic synchronous machines (PMSM) and brushless DC motors (BLDC).
The tuning of the modulation and control systems of our motors and turbo compressors, or of your electric motor, guarantees the highest converter operating efficiency and reduced motor losses. In the same converter we can operate with both pulse-width modulation (PWM), with varying switching frequencies, and pulse-amplitude modulation (PAM). Thanks to PAM technology, the output filter between Motor and Converter can be eliminated.
A Celeroton developed sensorless control method allows for complete speed control without an encoder or Hall sensors. Auto tuning, automatic control parameterization and support from Celeroton engineers results in a simple and fast commissioning.
