Introduced an integrated drive system with an open cooling circuit

• Industrial water transformation into drive system cooling water

• Efficient cooling concept reduces acquisition and operating costs

Based on the concept of Totally Integrated Drive System (IDS), Siemens has introduced an environmentally-friendly integrated drive system consisting of a SimoticsFD motor and a water-cooled Sinamics S120 inverter. The system uses an integrated cooling concept that converts available industrial water into driveline cooling water, allowing equipment, motors and frequency converters to share an open cooling circuit. The shared cooling circuit allows the frequency converter to eliminate cycle cooling and significantly reduce the required space while increasing economic and energy efficiency. This flexible drive system meets the complex application needs of the steel, automotive and process industries as well as marine and marine applications.

Water cooling is an effective method for heat dissipation of motors and inverters and is very important in the process industry. Siemens has introduced an efficient integration concept that minimizes water quality requirements. This means that any available water can be used for driveline cooling, including industrial water commonly used in the industrial sector and treated river water. Since the entire system is resistant to oxygen enrichment in the cooling water, it prevents harmful oxidation. No additives are required in the cooling water, which not only reduces the environmental impact of the drive train, but also simplifies commissioning and maintenance. The use of copper-nickel alloys ensures that the drive system is resistant to corrosion and microbial growth, thereby enhancing the durability of the system. In addition, an integrated cooling unit that water-cools the motor and frequency converter increases heat dissipation efficiency and significantly reduces the need for costly air conditioning systems. In addition, waste heat can be used effectively to increase the overall energy efficiency of the system and create possibilities for energy recovery (depending on the type of application). Thanks to the high degree of protection easily achieved by the frequency converter and the motor, this water-cooled system achieves the highest reliability even in harsh environments.
