Siemens adds water cooling to Sinamics S120 converters

November 21, 2016 - Based on its IDS concept, Siemens has announced an environmentally friendly integrated drive system for open circuits comprising Simotics FD motors and water- cooled Sinamics S120 converters. Using an integrated cooling concept, the system turns available service water into cooling water for the drive system, enabling a joint open cooling circuit for the plant, motor and converter. The joint cooling circuit allows the recooling module for the converter to be dispensed with. Flexible drive trains can be created to address complex applications in fields such as the steel, automotive and process industries, as well as for offshore and shipping applications.

Water cooling is a method of dissipating heat generated by the  motor and converter, and is particularly vital in the process industry. With its water- cooled drive system, Siemens is providing an efficient overall concept which makes minimal demands on the quality of the water. This means that any kind of available water, from service water customarily occurring in industry through to treated river water, can be used for drive system cooling. Because the overall system is resistant to oxygen enrichment of the cooling water, it is also able to prevent unwanted oxidation. Dispensing with additives in the cooling water lessens the environmental impact of the drive system. Use of a copper-nickel alloy makes the drive system for open circuits particularly corrosion-proof, resistant to biological growth and consequently durable. The integrated cooling concept with water cooling of both motor and converter makes for more efficient heat dissipation. The waste heat can additionally be put to good use, increasing the overall energy efficiency of the system and, depending on the application, opening up scope for regenerative feedback. The overall system with water cooling operates with the utmost reliability even in harsh environments due to the high protection ratings which can be implemented for both converter and motor.
