Project Description

DXFA 1-95
Dual application drive system

DAFA 31-91 series liquid resistance starters come in two editions. According to power range and analogue to the AFA series, either the blade or the classic ring electrode system is incorporated. These liquid resistance starters are used in mill drives where the motors operate in parallel. Mill drives operate through a reduction gear unit and cannot be coupled electrically due to the mechanical coupling of the grinder. With a liquid resistance starter from the DAFA series, every motor operating in parallel has its own electrode system that prevents large overloads from occurring in the drive or in the mill gearing. The highest levels of precision are achieved for the resistance values by keeping both electrode systems synchronised and by maintaining a constant electrolyte temperature and concentration.
