Kollmorgen 60WKS-CE240/12 PB
Product Brief: Compact rare-earth PMSM servo motor, frame 60 × 60 mm flange, with “CE240” winding (voltage/torque constant optimized for 240 VAC / 320 VDC bus). “/12” refers to feedback — Resolver (typically 12-pole or 1-pole 2-track — in AKM naming PB = resolver, smooth or keyed shaft, IP65). “PB” = Resolver feedback + keyed shaft + IP65 seals + standard connector. Exact AKM base model would be e.g. AKM61x-xxxxxxx per full part number — 60WKS-CE240/12PB is the abbreviated OEM/panel spec notation.
Detailed content
Frame Size Designation: AKM6x — 60 mm × 60 mm flange, shaft Ø 14 mm (typical for AKM6)
Winding Code: CE240 — denotes specific torque constant / Ke optimized for 240 V class (typical continuous stall torque for AKM62/63 ~1.2–2.2 Nm depending on stack)
Continuous Stall Torque (Tc — typical AKM63 with CE winding): ≈ 1.8 – 2.2 Nm (stack length dependent; AKM62 ~1.27 Nm, AKM63 ~2.07 Nm)
Peak Torque (Tp): ≈ 3× Tc (e.g. 6.2 Nm for AKM63 CE)
Rated Speed (Typical): 3000 rpm (standard winding); some CE windings also available 4000/5000 rpm — verify nameplate
Rated Power (Continuous): ≈ 0.4 – 0.65 kW (frame 60, stack dependent)
Rated Current (RMS): ≈ 2.5 – 4.0 A
Peak Current (RMS): ≈ 7.5 – 12 A
Torque Constant (Kt, CE winding): ≈ 0.55 – 0.75 Nm/A (line-to-line)
Back-EMF Constant (Ke, CE winding): ≈ 36–48 V/krpm (line-to-line RMS)
Feedback Device: Resolver — 2-pole (single-speed) or multi-speed per AKM “PB” option — drive performs electronic commutation from resolver signal
Brake: Not included in this spec (/12 PB implies no brake; brake would be denoted by “B” in AKM full pn)
Shaft Type: Keyed shaft (“P” = keyed in AKM code; “S” = smooth)
Sealing / Protection: IP65 (shaft seal + O-ring on connector)
Insulation Class: F (155 °C), 100 K rise above 40 °C ambient
Thermal Sensor: KTY84-130 or PTC (standard)
Connector Type: Rotatable M23 (17-pin for resolver + motor ID) or Intercontec, IP65 when mated
Housing Material: Aluminum alloy end bells, steel laminated stator, NdFeB magnets
Cooling: Natural convection
Operating Temperature (Ambient): 0 °C to +40 °C rated; –20 °C to +55 °C with derating
Weight (approx.): ≈ 2.5 – 4.0 kg (stack length dependent)
Mounting Pattern: 4× M6 on 70 mm BCD (AKM6 flange pattern)
Compliance: cURus, CE, RoHS
Applicable Industries: Electronics assembly pick-place, small packaging/form-fill-seal, labeling machines, medical diagnostic instrument stages, semiconductor probe handlers
Installation Requirements: Mount on machined 60 mm flange; align coupling; torque mounting bolts to spec; connect shielded cables; ground shield at drive end; verify resolver wiring (R1/R2/S1/S2/S3/S4) matches drive terminal assignment.
Usage Notes: AKD drive auto-detects AKM motor ID via resistor network in M23 connector and loads default parameters — always run “Auto Tune”; CE240 winding is 240 V class — suitable for AKD-B (120/240 V) and AKD-P 240/480 V drives; resolver feedback requires no battery backup for commutation; if machine requires holding brake specify AKM6x-…-B… variant.
