AKM21C-BNPNC-00 by Kollmorgen

The Kollmorgen AKM21C-BNPNC-00 servo motor is a precision component in the AKM Synchronous Servo Motors series, designed by Kollmorgen for high-performance motion control. Delivering a peak torque of 1.47 Nm and a rated torque of 0.39 Nm at 230 VAC, this compact motor provides exceptional responsiveness in dynamic applications. With a maximum speed of 8000 RPM and a standstill torque of 0.48 Nm, it offers both rapid acceleration and stable holding capability, making it ideal for robotic systems, automated assembly, and precision manufacturing.

In-depth technical specifications underscore the motor’s robust design. The six-pole stator configuration ensures smooth torque delivery and high efficiency across varying loads. A torque constant of 0.3 Nm/A and a maximum current draw of 6.3 A guarantee consistent power output under demanding conditions. The windings exhibit a resistance of 13 ohm and an inductance of 19 mH, optimizing electrical performance and minimizing thermal buildup. Single-turn inductive feedback turns enable accurate position sensing, while the NEMA flange configuration and smooth shaft facilitate straightforward integration.

Beyond raw performance, the AKM21C-BNPNC-00 excels in durability and installation flexibility. Weighing only 0.82 kg and measuring 76.1 × 95.4 × 129.5 mm (including brake), it fits space-constrained assemblies without compromising strength. It supports axial loads up to 60 N at 5000 RPM, ensuring reliable operation in mechanically demanding environments. Standard construction and single-turn feedback simplify maintenance, while the rotor length index of 1 and C-winding designation underscore compatibility with a broad range of drive controllers. In industrial settings, users benefit from streamlined integration, sustained precision, and energy-efficient operation, reinforcing Kollmorgen’s reputation for delivering motors that empower advanced automation solutions.
