Propulsion First AIM for CVF


from Converteam Power conversion specialist Converteam has completed delivery of the first of the propulsion motors for the UK Royal Navy’s Queen Elizabeth class aircraſt carriers as a part of the company’s contract to design and supply major components of the electric propulsion systems for the two new ships. At 65,000 circa tonnes each the two aircraſt carriers


will be the largest ships ever built for the Royal Navy and they will be propelled by a Converteam designed Integrated Full Electric Power (IFEP) system. Each ship is designed with two shaſt lines, each driven by two of Converteam’s Advanced Induction Motors (AIMs). Te first AIM, weighing approximately 110tonnes,


recently left Converteam’s Rugby factory on a 72-wheel trailer for a three-day journey to BAE Systems’ Govan shipyard where it was craned into position in one of the construction blocks of Queen Elizabeth almost immediately.


The first AIM is lowered in to place.


Converteam’s electrical propulsion expertise is also


being brought to bear via further critical elements of the IFEP system including the six generators, four high-voltage (11kV) switchboards, 12 VDM25000 variable-speed drives, the harmonic filters and the Electrical Power Control and Management System (EPCAMS). WT
