Totally Enclosed Eater Cooled Motors (TEFC Motors) is a design of asynchronous electric motors in a fully enclosed enclosure with a degree of protection IP55, IP56, IP65 with self–ventilation or forced cooling. Electric motors of alternating current TEFC Marelli Motors are manufactured with a power of up to 2 MW and a voltage of up to 11 kV.
Feature of operation: the design of the electric motor provides complete protection of the electromagnetic system from the effects of a negative external environment, forced cooling can be installed in severe operating conditions.
Depending on the nominal operating voltage and housing material, TEFC electric motors Marelli Motori they are classified by series:
- B5H – industrial high-voltage electric motors in a cast-iron case;
- B5M – high-voltage, low-voltage marine engines;
- A5M - high-voltage, low-voltage motors in marine aluminum housing;
- B5C, B6C – industrial low-voltage electric motors in cast iron housing;
- A5C, A6C are general industrial low–voltage electric motors in an aluminum housing.
