Description
Product Description
The Siemens 6SE7027-2ES87-1FE0 is a high-performance output reactor designed for SIMOVERT MASTERDRIVES and compatible SINAMICS drive systems. Installed between the inverter and motor, this three-phase reactor minimizes voltage peaks, reduces motor insulation stress, suppresses electromagnetic interference (EMI), and improves overall drive system reliability. It is designed for 380–460 V AC applications with a rated current of 72 A, supporting output frequencies up to 120 Hz and a pulse frequency of 3 kHz.
The reactor enables longer motor cable lengths while protecting motors from PWM-induced voltage reflections and bearing currents. It is widely used in CNC machinery, robotics, conveyors, packaging equipment, material handling systems, and other demanding industrial automation applications where reliable motor protection and enhanced EMC performance are essential.
