Kollmorgen AKM22E-ENB2DB0
Product Brief: Compact high-torque-density PMSM servo motor, frame 22 (70 × 70 mm IEC flange — NEMA 34 mini), E-winding = medium stack for AKM22 (continuous stall torque ~1.27 Nm). Factory-fitted with EnDat 2.1/2.2 absolute multiturn encoder (“EN” = EnDat in AKM2x code — “ENB2” = EnDat, B = keyed shaft, 2 = IP65 seals, DB0 = brake + connector config), keyed shaft, 24 VDC spring-applied holding brake (“DB” or “B” in brake position), rotatable M23 connectors (separate power+brake and feedback). Auto-recognizable by AKD/S700 drives via motor ID resistor network.
Detailed content
Frame Size Designation: AKM22 — Flange 70 mm × 70 mm, pilot Ø 60 mm, 4× M6 on 85 mm BCD
Shaft Diameter: 14 mm — Keyed shaft (DIN 6885 keyway)
Continuous Stall Torque (Tc @ 40 °C): ≈ 1.27 Nm (E-winding, AKM22E)
Peak Torque (Tp, < 3 s): ≈ 3.8 Nm
Rated Speed (Maximum): 6000 rpm (E-winding); continuous power speed ~3000 rpm
Rated Power (Continuous): ≈ 0.4 kW @ 3000 rpm
Rated Current (RMS, continuous): 2.0 A
Peak Current (RMS): 6.0 A
Torque Constant (Kt, line-line): ≈ 0.64 Nm/A
Back-EMF Constant (Ke, line-line): ≈ 42 V/krpm (RMS)
Winding Resistance (Line-Line, 25 °C): ≈ 3.5 Ω
Winding Inductance (Line-Line): ≈ 8.5 mH
Rotor Inertia (without brake): 0.17 × 10⁻⁴ kg·m² (0.17 kg·cm²)
Feedback Device: EnDat 2.1/2.2 absolute encoder (multiturn, 24-bit typical) — option EN
Brake Specification: 24 VDC spring-applied, power-off engaged; Holding torque ≈ 1.3–1.5 Nm (typical AKM22 brake); Release current ~0.5 A; Power consumption ~12 W
Thermal Sensor: KTY84-130 or PTC
Insulation Class: F (155 °C)
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; aluminum alloy end bells; NdFeB magnets
Connector Type: Rotatable M23 SpeedTec — separate connectors for power+brake and feedback
Weight (with brake, approx.): ≈ 2.2 – 2.5 kg
Compliance: cURus, CE, RoHS
Applicable Industries: Small-to-mid packaging pick-place, labeling machine indexers, electronic assembly handlers, printing press register axes, textile guide rollers
Installation Requirements: Mount on machined 70 mm flange with 4× M6 bolts torqued to spec; align load coupling coaxially (max overhung radial load ≈ 150 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 ~12–15 min; brake is hold-only — stop motor electronically before brake engagement; smooth shaft version available if “S” instead of “N” in shaft code.
