DC Motors

comap

The "Special" IEC Standard.
 
The A.C. generator operated by diesel motors of high vibrations and D.C. traction motor are the electrical machines with the highest exigency in their service.
 
The equipment and experience developed by CRAMACO®, in addition to the high technology, are now applied to C.A. Three-phase Motors - Type Cage Induction to manufacture the high confiabilitySpecial IEC Standard.
