AKM42J-ACCNEF-00 by Kollmorgen

The Kollmorgen AKM42J-ACCNEF-00 servo motor from the AKM Synchronous Servo Motors series delivers a compact yet powerful solution for industrial automation and motion control tasks. Designed for wide compatibility, the AKM42J-ACCNEF-00 supports multiple feedback options, including SFD3, HIPERFACE DSL, Resolver, EnDat 2.2/01, and BISS, ensuring seamless integration with modern control platforms. With a robust construction meeting CE, cRUus, EAC, RoHS, and REACH certifications, this motor guarantees reliability and safety across global installations. The inclusion of a high-performance brake unit provides an additional 6 N-m brake torque for secure holding in vertical or suspended load applications. Engineers will appreciate the optimized form factor, where a frame dimension of 84 mm and total motor length of 147.8 mm minimize footprint without compromising output.

Detailed specifications of the AKM42J-ACCNEF-00 underpin its precision and performance. The motor delivers a continuous stall torque of 3.56 N-m at 8.4 Arms (120 VAC) continuous stall current and achieves a peak stall torque of 11.6 N-m for dynamic acceleration demands. It sustains speeds up to 4030 RPM at 120 VAC and a maximum of 6000 RPM at 240 VAC, while the back EMF constant of 27.5 Vrms/kRPM ensures predictable voltage-to-speed characteristics. The rotor assembly, with a rotor inertia of 0.000145 kg·m² and rotor length index of 2, provides a balance between agility and stability. Connectivity is simplified by the 2 SpeedTec Ready connectors on an IEC flange with accuracy N, coupled with a keyed shaft detail accommodating a 19 mm shaft diameter and 40 mm shaft length.

Operational features emphasize performance and maintainability in harsh environments. The AKM42J-ACCNEF-00’s J winding designation is optimized for thermal management under continuous load conditions, while the absence of an integrated brake system in certain variants reduces overall motor mass. Its compact construction yields excellent acceleration response and repeatability, even under fluctuating loads, supported by advanced feedback reliability. Maintenance downtime is minimized through standardized connectors and plug-and-play compatibility, simplifying wiring and diagnostics. The robust IEC flange and shaft keyway design ensure secure coupling to gearboxes or other mechanical interfaces, promoting high uptime in critical industrial installations.

System integrators will find the AKM42J-ACCNEF-00 ideal for applications in packaging, robotics, CNC machinery, and other precision automation scenarios. Its combination of global certifications, flexible feedback support, and compact dimensions streamlines machine design and regulatory approval processes. When paired with Kollmorgen servo drives, it delivers advanced motion control features such as auto-tuning, vibration suppression, and real-time diagnostics. This motor is purpose-built for engineers seeking reliable, high-performance motion solutions in demanding industrial environments.
