Frequency Converter SD2S-FPAM
Highest speeds, lowest motor heating and best control performance – always in real time: The technical basis is the controlled intermediate DC circuit combined with the established pulse-amplitude modulation (PAM) which allows SD2S doing without additional motor chokes even at high speeds.
Based on this technology SIEB & MEYER developed two extremely robust and sensorless control methods: V/f-PAM for asynchronous motors and FPAM for synchronous motors. The usually very special applications in this area require close coordination between the user and SIEB & MEYER. Applications with a large variance of engine types (such as engine test stations) are rather unsuitable.
