Three-phase Asynchronous Marine Motors
| Power outputs | 0,12 - 75kW |
| Voltages | Up to 830V |
| Frames | 63 - 280 |
| Efficiency classes | IE2 - IE3, where applicable |
| Sectors | Marine |
| Most common applications | Fans / Pumps / Lifting Systems |
The electric motors for the marine sector are meant for on-board auxiliary services up to 100kW. Reliability in aggressive environments and under sensitive mechanical stresses make our products the ideal choice to drive pumps, fans, air treatment systems and, above all, critical services such as over-deck lifting cranes.
