Description
Product Description
The Siemens 6SE7031-8ES87-1FE0 is a heavy-duty output reactor designed for use with SIMOVERT MASTERDRIVES and compatible SINAMICS drive systems. Installed between the inverter and motor, this three-phase output reactor minimizes PWM-induced voltage peaks, reduces motor insulation stress, suppresses electromagnetic interference (EMI), and enhances overall drive system reliability. With a rated current of 180A and an operating voltage range of 380–460V AC, it is engineered for demanding industrial motion control applications requiring high power and dependable motor protection.
The reactor helps reduce cable reflections, limits motor bearing currents, and enables longer motor cable lengths while improving electromagnetic compatibility (EMC). It is ideally suited for high-power drive systems used in CNC machine tools, robotics, material handling equipment, cranes, conveyors, packaging machinery, and automated manufacturing facilities.
