Siemens Launches Integrated drive system with open cooling circuit

by:V&T Technologies     2020-02-17
Based on fully integrated drive system (IDS) Concept, Siemens recently introduced an environment-friendly integrated transmission system composed of Simotics FD motor and water-cooled Sinamics S120 inverter. The system adopts the integrated cooling concept and converts available industrial water into cooling water for the transmission system, so that the equipment, motor and frequency converter share the open cooling circuit. The shared cooling circuit enables the frequency converter to save circulation cooling links, greatly reducing the required space while improving economic and energy efficiency. This flexible transmission system can meet the complex application requirements of steel, automobile and process industries as well as the application requirements of offshore and ships. Water cooling is an effective heat dissipation method for motors and frequency converters, which is very important in the field of process industry. Siemens has introduced an efficient integration concept to minimize the requirements for water quality. This means that any available water can be used for cooling the transmission system, including industrial water commonly used in the industrial field and treated river water. Because the whole system can resist oxygen enrichment in cooling water, it can prevent harmful oxidation. No additives are needed in the cooling water, which can not only reduce the environmental impact of the transmission system, but also simplify debugging and maintenance. The use of copper-nickel alloy can ensure the corrosion resistance and anti-microbial growth of the transmission system, thus enhancing the durability of the system. In addition, the integrated cooling device for cooling the motor and frequency converter can improve the heat dissipation efficiency and greatly reduce the demand for expensive air conditioning systems. In addition, waste heat can also be used effectively, improve the overall energy efficiency of the system, and create possibilities for energy recovery (Depending on the type of application). Due to the high protection level of frequency converter and motor, this water cooling system can achieve the highest reliability even in harsh environment.
