Kollmorgen 60WKS-CE240/22PB Brushless Servo Motor

The Kollmorgen 60WKS-CE240/22PB is a high-torque synchronous servo motor engineered for precision motion control in industrial automation and robotics. Part of Kollmorgen’s renowned AKM series, this brushless PMAC motor combines 22 Nm continuous torque with 240mm frame compactness, delivering exceptional power density for space-constrained applications. The 60WKS-CE240/22PB features a stainless steel shaft, IP65-rated housing, and advanced winding technology that minimizes torque ripple to <±0.5% – critical for smooth velocity control in semiconductor manufacturing and optical alignment systems. With its integrated 22-bit multiturn absolute encoder (Hiperface DSL® interface), this motor achieves ±15 arc-second positioning repeatability without homing routines. The Kollmorgen 60WKS-CE240/22PB excels in dynamic applications requiring rapid acceleration, with a rotor inertia optimized for 50:1 inertia mismatch compensation when paired with Kollmorgen AKD drives. Its forced-air cooling design sustains rated torque up to 4,000 rpm, making it ideal for high-duty-cycle automation.

Technical Specifications

Ultra-High Torque Density: Neodymium magnet technology delivers 22 Nm continuous torque in a compact 240mm frame – 35% higher than comparable IEC motors. Enables direct drive of heavy loads without gearboxes.

Precision Motion Control: The 22-bit encoder provides 4,194,304 counts/revolution resolution for micron-level positioning (±15 arc-second repeatability). Hiperface DSL® protocol allows single-cable connectivity with Kollmorgen AKD drives.

Zero-Cogging Design: Optimized slotless stator eliminates detent torque (<±0.5% ripple), ensuring buttery-smooth motion at low speeds (<1 rpm) for microscopy stages or wafer inspection.

Robust Construction: Hard-anodized aluminum housing withstands washdown environments. Double-sealed bearings rated for 20,000 hours at 4,000 rpm. Stainless steel shaft resists corrosion in chemical processing.

Thermal Efficiency: Patented cooling fins increase surface area by 40%, sustaining rated torque at 4,000 rpm without external cooling. Embedded thermistors provide real-time winding temperature feedback.

Dynamic Response: Low rotor inertia (0.037 kg·m²) enables 20,000 rad/s² acceleration – ideal for pick-and-place robots with <50ms cycle times.

The Kollmorgen 60WKS-CE240/22PB excels in high-precision, high-duty-cycle automation:

Semiconductor Equipment: Direct-drive wafer handling robots requiring <10µm positioning repeatability

Packaging Machinery: High-speed rotary fillers processing 600+ bottles/minute

Medical Automation: CT scanner gantries demanding vibration-free rotation

Industrial Robotics: Articulated arm joints for automotive assembly (ISO 9409-1 flange)

Printing Presses: Web tension control with <0.1% speed regulation

Test & Measurement: Precision turntables for optical component calibration

Installation and Maintenance

Pre-installation preparation: Verify shaft alignment (<0.05mm radial misalignment). Use flexible coupling to absorb axial displacement. Ground motor housing directly to machine frame (min. 10mm² cable).

Maintenance recommendations: Inspect seals annually for integrity in washdown environments. Monitor winding temperature via drive software; replace if exceeding 155°C sustained. Relubricate bearings every 10,000 hours with Kluber Staburags NBU 12/300 EP grease. Avoid compressed air cleaning near encoder.
