| This latest generation of electrically commutated circulation pumps have an integrated frequency converter and a permanent magnet motor. |
| Thanks to the electronic commutation of the drives, the lifetime is much longer in comparison with mechanically commutated motors. |
| The units provide sinusoidal commutated motor drive as well as field-oriented motor control. |
| Commutation failure in line commutated converter based HVDC systems cause severe damages on the entire power grid system. |
| In this paper we present a system for assessing the quality of electronically commutated motors. |
| This brings an additional degree of freedom compared to line commutated switches. |
