Shipbuilding

VEM has many years of experience in building ship motors and it also has the licences from all of the important ship classification companies. We build and supply motors and generators for a wide range of all ship models. They range from the large-scale machine with a weight ranging from 200 tonnes to the broad spectrum of accessory drives. Our scope of delivery includes shaft, diesel and on-board electrical system generators, propeller drives, bow thrusters and transverse rudder drives, pump drives and drives from on-board auxiliary equipment.

VEM asynchronous motors designed for the upper low-voltage and medium-voltage range are in wide use in a variety of forms as deck and auxiliary equipment drives.Applications include cutter-head drives on work barges and pump motors for suction-dredge ships or tankers.

Output range: 500 – 5,000 kW
Voltage range: 400 – 11,000 V
Frequency: 50 Hz, 60 Hz or for converter operation
Speed range: 500 – 1,800 r.p.m.
Number of poles: 4- to 12-pole
Cooling types: IC 8A1 W7 and IC 01

VEM generators are manufactured as nonsalient or salientpole machines with welded housing and brushless excitation.

The machines are equipped as required, with digital controllers and accompanying monitoring systems.
The majority of our generators use sliding bearings with flange mounting, though antifriction bearings may be used for machines with a lower output. Generators with a particularly high output also come with pedestal bearings, along with the complex oil-feed units these require.

Output range: 500 – 30,000 kVA
Voltage range: 400 – 11,000 V
Speed range: 500 – 1,800 r.p.m.
Number of poles: 4- to 14-pole
Cooling types: IC 8A1W7
