Introduction Innovative drives made in Germany Electric machines made by VEM have millions of applications around the globe. VEM stands for high-quality products such as large and special-purpose machines, standard motors and customized drives which have given reliable service in a variety of industries. Systems of all types use our motors, generators and drives for a wide range of voltages. They have stood the test for decades even under extreme conditions – whether in the dust and heat of mill trains, chemical plants with explosion hazards, or in the moist, salty air aboard ships. Our...

Technical explanations Application Motors in sea-water design have to be equipped at a high technical level, because they are subject to special environmental and operational conditions. The requirements for reliability are high and they are also subject to special regulations. Motors in sea-water design are used as drives for ancillary units on board of ships and they comply with the special climatic and mechanic loads of these application ranges. To ensure a high-quality engineering and technological design for new developments, reconstructions and repairs of ships the working procedures...

Technical explanations Technical data The performance characteristics can be taken from the lists for motor selection data. For more important hints for selection of three-phase asynchronous motors please refer to the VEM main catalogue “Low voltage asynchronous motors, IEC motors with squirrel-cage rotor”. If the operation on board of ship is only permitted under observance of additional regulations like gas or dust explosion protection, please use the corresponding motor series. Dimensions and types of construction The mounting and assembly dimensions comply with the values for the basic...
