Alternator IP-54
HEIMER LAUNCHES ALTERNATOR TYPE ated / TFVE
FULLY CLOSED
Alternators Heimer represent the latest in electrical rotating machines, due to the improvement of electromechanical projects and experience gained in several decades. Made with the most modern building techniques and using the best materials available to ensure their flawless performance and durability.
The alternators Heimar are characterized by their mechanical protection IP-54 (mechine protected against dust and machinery aspersion from any direction), allowing its use in spacecraft to prospect of oil or in any environment that produce high levels of pollution (particulate matter, gases , etc.) it's eccitation system is do thruogh out it's rotative eccitation of alternative electrical curent and fixed pole.
The continuous power for excitation of the main field is obtained by rectifying the ac three-phase exciter, through rotating bridge rectifier system (brushless).
