Defining the 1FK7 compact synchronous motor
The Siemens 1FK7022-5AK71-1PG0 is a 1FK7 COMPACT SYNCHRONOUS MOTOR — a brushless servo in the compact-frame tier used on Siemens SINAMICS drive packages where the machine builder needs tight dynamic response from a small-footprint, low-inertia rotor. Its class role: a permanent-magnet synchronous servo sized for machine-tool axes, packaging lines, and small-format pick-and-place or feeder drives — applications where the synchronous rotor delivers the holding torque and positioning accuracy an induction motor cannot.
Sourcing posture when the factory has stopped
For a buyer who arrived with this exact code because a 1FK7 axis is down or a spare slot must be filled, the storefront sources it through independent distribution — quoted to order against the RFQ, with availability and pricing confirmed at quote time and no stock or immediacy claim attached.
