0.2 kW, 1.1 A, 3000 r/min — the rating envelope
The HC-KFS23 is a Mitsubishi Electric small-frame AC servo motor in the Servo Motors category, rated 0.2 kW at 3000 r/min — a footprint sized for low-inertia positioning axes such as feeders, labelers, and small conveyor indexing stations where the load moves fast but does not need to be heavy. Rated current sits at 1.1 A with a maximum current ceiling of 3.4 A; the ~3× overload headroom is what lets the motor punch above its continuous figure during acceleration ramps before the drive folds back into the rated envelope.
Speed ceiling and dynamic headroom
Maximum speed is 4500 r/min and permissible instantaneous speed reaches 5175 r/min — that overspeed margin is the safety the drive firmware leans on when a fast index stroke trips a transient overshoot, not a continuous operating point. A 0.5 kVA power facility capacity and a 15.8 kW/s power rate at continuous rated torque point to a responsive low-inertia rotor — adequate for short-cycle point-to-point moves, modest for high-inertia direct-coupled loads.
Lifecycle heat — sourcing through independent channels
Lifecycle stage is flagged EOL/HOT — the part is past its primary window with the original manufacturer, and the realistic path is independent distribution rather than factory-direct replenishment.
