Kollmorgen AKM41H-AN92GF0
Product Brief: High-torque-density 3-phase PMSM servo motor, frame 41 (100 × 100 mm IEC flange), H-winding = medium stack length for AKM41 (continuous stall torque ~4.8–5.5 Nm). Factory-fitted with EnDat 2.1/2.2 absolute multiturn encoder (option “92G”), keyed shaft (“N” = keyed in AKM code — confirmed by AN92GF0 where ‘N’ = keyed), 24 VDC spring-applied holding brake (“F” = brake present), and standard IP65 shaft seal + rotatable M23 feedback/power connectors. Auto-recognizable by AKD/S700 drives via motor ID resistor network.
Detailed content
Frame Size Designation: AKM41 — Flange 100 mm × 100 mm, pilot Ø 80 mm, 4× M8 on 115 mm BCD
Shaft Diameter: 19 mm — Keyed shaft (DIN 6885 keyway)
Continuous Stall Torque (Tc @ 40 °C, 100 K rise): ≈ 5.3 Nm (H-winding typical)
Peak Torque (Tp, < 3 s): ≈ 15.9 Nm
Rated Speed (Maximum): 6000 rpm (H-winding); continuous power speed ~3000 rpm
Rated Power (Continuous): ≈ 1.66 kW @ 3000 rpm
Rated Current (RMS, continuous): 3.9 A
Peak Current (RMS): 11.7 A
Torque Constant (Kt, line-line): ≈ 1.36 Nm/A
Back-EMF Constant (Ke, line-line): ≈ 90 V/krpm (RMS)
Winding Resistance (Line-Line, 25 °C): ≈ 1.85 Ω
Winding Inductance (Line-Line): ≈ 12 mH
Rotor Inertia (without brake): 1.77 × 10⁻⁴ kg·m² (1.77 kg·cm²)
Feedback Device: EnDat 2.1/2.2 absolute encoder (multiturn, 24-bit typical) — option 92G
Brake Specification: 24 VDC spring-applied, power-off engaged; Holding torque ≈ 5 Nm (typical AKM size 41 brake); Release current ~0.5 A; Power consumption ~12–18 W
Thermal Sensor: KTY84-130 or PTC (100 °C trip typical)
Insulation Class: F (155 °C), 100 K rise above 40 °C ambient
Protection Class: IP65 (shaft seal + O-ring on connector)
Cooling: Natural convection
Operating Temperature (Ambient): 0 °C to +40 °C rated; –20 °C to +55 °C with derating
Housing Material: Black painted steel lamination stack; cast aluminum end bells; NdFeB magnets
Connector Type: Rotatable M23 SpeedTec — separate connectors for power+brake and feedback (or combo per config)
Weight (with brake, approx.): ≈ 5.5 – 6.0 kg
Compliance: cURus, CE, RoHS, REACH
Applicable Industries: Printing press print units, converting winders/unwinders, packaging form-fill-seal main drives, CNC rotary tables, textile take-up rolls
Installation Requirements: Mount on machined 100 mm flange with 4× M8 bolts torqued to spec; align load coupling coaxially (max overhung radial load ≈ 300 N at shaft end); bond PE terminal to machine ground; connect shielded cables — shield grounded at drive end only; brake wired to drive brake output or external 24 V supply with freewheeling diode.
Usage Notes: AKD drive auto-loads motor parameters from ID resistors — always execute “Tune” after first detect; EnDat encoder requires proper 5 V supply from drive; thermal time constant ≈ 20–25 min — respect continuous torque limit; brake is hold-only — stop motor electronically before brake engagement.
