Under that lifecycle, this synchronous servo motor — a 3-phase AC unit rated for 3000 rpm — is the kind of part buyers reach for when an existing axis must be restored like-for-like rather than redesigned around a current SIMOTICS frame. ## 3000 rpm synchronous servo — what the class does on the machine The 1FK7084 series sits in the SIMOTICS S family of brushless synchronous servomotors, paired on machine-tool, packaging and converting axes with a SINAMICS S120 drive that handles the commutation and the speed/position loop. A 3-phase AC synchronous servo at 3000 rpm is the workhorse rating for indexing tables, feed axes and rotary knife drives where the holding torque at standstill and the dynamic response through acceleration ramps matter as much as the top speed. ## Sourcing posture for a hot EOL servo motor With lifecycle set to eol_hot, the realistic supply channel for the 1FK70843BF711EB0 is independent distribution drawing on decommissioned machine stock, panel-builder surplus and the broker network — quoted against an RFQ with the date code, encoder variant and shaft detail confirmed against the nameplate before the PO is cut.","metaTitle":"Siemens 1FK70843BF711EB0 Servo Motor, 3AC, 3000 rpm","metaDescription":"Siemens 1FK70843BF711EB0 synchronous servo motor, 3-phase AC, 3000 rpm.
