DC ELECTRIC MACHINES OF GENERAL USAGE
APPLICATION
DC motors and generators produced by ELMOR S.A. are provided for operation at sea and land in various climate conditions.
TECHNICAL CHARACTERISTIC
Various types of fixing are possible (on feet, with a flange for horizontal operation, with flange for vertical operation, on feet with flange for horizontal operation). Various kinds of excitation are available (shunt excitation, compound excitation, series excitation). Insulation class B or F. Motors are made with a brake or without as drip-proof (IP22) and splash-proof (IP44, IP55, IP56). Generators are made as drip-proof (IP22); they are equipped with condensers, which together with windings of commutating poles create an interference eliminator. They can be driven by petrol motors, diesel engines, electric motors, etc.
TECHNICAL PARAMETERS
Generators
Powers are given for operation S1; voltage 115V or 230V; protection degree IP22.
