Low-voltage Marine propulsion motors

VEM motors and drives designed and intended for use in auxiliary power units on board of oceangoing vessels live up to those specific requirements encountered in such environments. These are, among others, high atmospheric humidity and salt content in the air, marine splash water and major temperature fluctuations. These motors conform to the requirements of national and international classification societies. They are designed according to and available with various types of protection and type series and for operation on deck or under deck respectively.
