Kollmorgen B-104-A-34-B3
Product Brief: 3-phase interior permanent magnet (IPM/NdFeB) synchronous servo motor offering high torque density and low cogging for dynamic point-to-point motion. Frame “10” = B-10x — flange 63.5 mm × 63.5 mm (NEMA 23), pilot ≈ 47.6 mm, 4× M5 on 70 mm BCD. “A” = winding code (lowest torque constant / highest speed in B-10 family). Factory-fitted with 2-pole resolver (standard on Goldline B). “34” in option string = smooth or keyed shaft + standard seals; “B3” = connector type/orientation + special oil seal (B3 typically = MS/circular connector, shaft seal, keyed shaft — verify from nameplate). Compatible with SERVOSTAR S300/S600/S700 and AKD (120/240 V models).
Detailed content
Frame Size: B-10x — Flange 63.5 mm × 63.5 mm (NEMA 23), shaft Ø 9.525 mm (3/8 in) with keyway (typical for B-104 with keyed shaft option)
Rated / Continuous Stall Torque (Tc, A-winding): ≈ 0.40 – 0.50 Nm
Peak Torque (Tp, short-term): ≈ 1.2 – 1.5 Nm
Rated Speed (nN): 3000 rpm (A-winding @ 230 VAC line)
Rated Power (Continuous): ≈ 0.13 – 0.16 kW
Rated Current (RMS): ≈ 1.1 – 1.5 A
Peak Current (RMS): ≈ 3.3 – 4.5 A
Torque Constant (Kt, line-line): ≈ 0.35 – 0.42 Nm/A
Back-EMF Constant (Ke, line-line): ≈ 22–28 V/krpm (RMS)
Winding Resistance (Line-Line, 25 °C): ≈ 8 – 12 Ω
Winding Inductance (Line-Line): ≈ 10 – 20 mH
Rotor Inertia (without brake): ≈ 0.027 × 10⁻⁴ kg·m² (0.027 kg·cm²)
Brake: None (unless -Bxx option present)
Feedback Device: 2-pole Resolver (standard Goldline B)
Insulation Class: Class F (155 °C), 100 K rise above 40 °C ambient
Protection Class: IP65 (shaft seal + O-ring on connector when mated)
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 bell; NdFeB magnets
Connector Type: Circular military-style or Intercontec M16/M23 (power + feedback pins)
Weight (approx.): ≈ 1.3 – 1.6 kg
Mounting Pattern: 4× M5 on 70 mm BCD (NEMA 23 pattern)
Compliance: cURus, CE
Applicable Industries: Small packaging pick-place heads, labeling machine indexers, electronic component inserters, medical diagnostic instrument stages, textile yarn guides
Installation Requirements: Flange-mount on machined NEMA 23 pattern; align load coupling coaxially (max overhung radial load ≈ 60 N at shaft end); torque mounting bolts to spec; connect PE; use shielded feedback cable with shield grounded at drive end only.
Usage Notes: Goldline B is discontinued — AKM2x/3x (AKM22/23/24) are functional replacements; verify feedback type (resolver standard) matches drive before commissioning; resolver auto-commutated by AKD/S700; thermal time constant ~10–15 min — respect continuous torque limit; B-104-A-34-B3 resolver is 2-pole single-speed.
