The 1FK7 frame on a high-dynamic axis
The 1FK7044-4CH71-1CG2 is the catalogued 1FK7 HIGH DYNAMIC SYNCHRONOUS MOTOR from Siemens, sitting in the Servo Motors line under Motors & Motor Controls. It pairs with a SIMOVERT or SINAMICS-class servo drive and is sized for axes where the cycle demands quick acceleration and a short mechanical time constant — typical of feed axes on machine tools, packaging heads, and indexing tables.
