Part number 1FK7086-7AF71-1SA0-Z from Siemens, listed in Servo Motors. KKM Solutions quotes this part with pricing and availability confirmed per order.

The Siemens 1FK7086-7AF71-1SA0-Z is a SIMOTICS S-1FK7 high dynamic synchronous (permanent-magnet) servomotor from the 1FK7 Generation 2 family, designed for use with SINAMICS S120 drive systems. It belongs to the shaft-height 80 mm frame (1FK7086) compact-design class and is intended for demanding motion-control applications such as machine tools, production machinery, packaging, handling and robotics where high dynamic response, smooth running and precise positioning are required. The motor uses a three-phase stator with rare-earth permanent magnets in the rotor, natural cooling, and integrated electronic identification via the DRIVE-CLiQ encoder interface. The order code suffix 1SA0 indicates an absolute encoder (single-turn, DRIVE-CLiQ) with a plain shaft end (without feather key) and no holding brake; the trailing -Z denotes additional factory-configured options specified at the time of order.
