In this paper we present a system for assessing the quality of electronically commutated motors. |
Commutation failure in line commutated converter based HVDC systems cause severe damages on the entire power grid system. |
The required dynamics narrow the options to electronically commutated motors. |
This brings an additional degree of freedom compared to line commutated switches. |
The Mentor MP, in common with all naturally commutated thyristor drives, causes voltage notches at the input supply terminals. |
This latest generation of electrically commutated circulation pumps have an integrated frequency converter and a permanent magnet motor. |
