Description

The KOLLMORGEN AKM42E-EKGNR-01 is a high-torque-density frameless servo motor engineered for direct integration into precision motion systems requiring exceptional dynamic response and space optimization. As part of Kollmorgen’s flagship AKM® series, this 42 mm diameter motor delivers 0.97 Nm continuous torque and 3.2 Nm peak torque in a minimalistic package, eliminating the need for couplings and reducing mechanical complexity. The KOLLMORGEN AKM42E-EKGNR-01 features a high-energy neodymium iron boron (NdFeB) magnet rotor with Kollmorgen’s proprietary thermal management design, enabling continuous stall operation at 155°C winding temperature. Its frameless architecture (stator + rotor only) allows OEMs to embed the motor directly into machine structures – ideal for robotic joints, medical actuators, and semiconductor handling equipment.

Equipped with a 20-bit single-turn EnDat 2.2 absolute encoder, the KOLLMORGEN AKM42E-EKGNR-01 achieves ±40 arc-second positioning accuracy while supporting high-speed serial communication for real-time feedback. The motor’s low cogging design (<1>KOLLMORGEN AKM42E-EKGNR-01 enables advanced control modes like adaptive ripple compensation and notch filtering to neutralize mechanical resonances. Its IP65-rated stator windings withstand contaminated environments common in food processing and pharmaceutical manufacturing.

Technical Specifications

Main Features and Advantages

Ultra-Compact Power Density: At just 42 mm diameter, the KOLLMORGEN AKM42E-EKGNR-01 delivers 30% higher continuous torque per volume than competing frameless motors. Its segmented lamination stator minimizes iron losses for sustained overload capability.

Precision Feedback Integration: The embedded EnDat 2.2 interface provides 0.00034° resolution with cyclic redundancy check (CRC) error detection. BiSS-C compatibility allows operation with third-party drives without signal conversion.

Thermal Robustness: Vacuum pressure impregnation (VPI) windings and high-temperature magnets maintain torque linearity up to 155°C ambient. Thermal sensors (KTY84-130) enable predictive overload protection in servo drives.

Electromagnetic Optimization: Asymmetrical pole design reduces cogging torque to <0>KOLLMORGEN AKM42E-EKGNR-01 achieves sinusoidal back-EMF with <3>

Application Field

The KOLLMORGEN AKM42E-EKGNR-01 excels in space-constrained, high-precision motion systems. In surgical robots, it drives force-limited joints with sub-degree positioning accuracy, integrated directly into sterilizable aluminum housings. Semiconductor wafer handlers leverage its vacuum-compatible construction for atmospheric-to-UHV transfer arms.

Packaging machinery utilizes this motor for flying cutters requiring 100 ms acceleration to 6,000 RPM with micron-level registration. For aerospace test equipment, the KOLLMORGEN AKM42E-EKGNR-01 simulates control surface loads in compact fatigue test rigs. Textile manufacturing employs it in yarn tensioners where low torque ripple prevents fiber breakage. Electric vehicle gearbox test stands benefit from its frameless integration into load simulators, delivering 98% efficiency during regenerative braking cycles.
