Kollmorgen AKM43K-ANSN2-02
-
Product Name: AKM™ Series AC Synchronous Servo Motor, Frame AKM43 (Flange 84 mm × 84 mm), Stack Length 3 (long), Winding Type K (high-torque / 480 V class), with resolver or optical encoder (AN = resolver or specific feedback per code), no brake, M23 connectors
-
Typical Parameters (AKM43K — 480 V / 640 V DC bus):
-
Continuous (Stall) Torque: ≈ 3.0–3.4 N·m (27–30 lb-in)
-
Detailed content
-
-
Peak Torque: ≈ 9.5–10.5 N·m
-
Rated Speed: 3000 RPM (typical for K winding)
-
Max Speed: 4500–5000 RPM
-
Continuous Current: ≈ 4.5–5.5 A RMS
-
Pe-Max Current: ≈ 14–16 A RMS
-
Torque Constant (Kt): ≈ 0.65–0.72 N·m/A RMS
-
Back EMF Constant (Ke): ≈ 45–50 V/kRPM (line-line RMS)
-
Rotor Inertia: ≈ 0.0013 kg·m²
-
Feedback: Resolver (code AN typically = resolver; SN may indicate SinCos encoder — verify from original order)
-
Brake: None (“02” = no brake)
-
Shaft: Keyway or plain (verify per option; AKM4 std = keyway)
-
Connector: 2 × M23
-
IP Rating: IP65 (with seal)
-
-
Applications: Medium-duty packaging axes, rotary tables, small conveyor drives, labeling stations.
-
Notes: “ANSN2” in Kollmorgen AKM coding typically means: A = AKM4 frame family, N = no brake, S = smooth or keyed shaft (check), N2 = resolver feedback + standard seal. Always confirm exact feedback type from motor nameplate before connecting to drive feedback port.
