The AKM21G-BNM22-00 from Kollmorgen is a high-performance member of the AKM Synchronous Servo Motors series designed for demanding industrial automation environments. This robust 3-phase motor operates at an input voltage of 230 V and delivers a rated load of 2 HP, ensuring reliable power for precision tasks. With a standstill torque of 0.50 Nm and a peak torque of 1.51 Nm, the AKM21G-BNM22-00 provides both steady-state control and dynamic overload capacity. The motor’s rotor moment of inertia of 0.11 kgcm² supports rapid acceleration and deceleration cycles without compromising stability. Compact yet powerful, this servo solution balances torque density and minimal footprint for space-constrained installations.
Technical performance is anchored by the Frequency Inverter Drive architecture, which delivers smooth current modulation across all 3-Phase windings. The motor’s winding inductance of 2.18 mH and torque constant of 0.10 Nm/A optimize responsiveness and energy efficiency during transient loads. High-resolution positioning is achieved via the integrated Comcoder feedback system, ensuring sub-millimeter accuracy in motion control loops. The smooth shaft and NEMA flange configuration simplify mechanical integration, while the frame dimension of 58 mm provides a standardized envelope for mounting and alignment. With a rotor length index of 1, the design maintains low inertia without sacrificing torque output.
Operational reliability is elevated by the inclusion of a 24V holding brake, which secures the load instantly upon power loss or command hold. The winding designation G and standard customization level guarantee reproducible manufacturing quality and streamlined maintenance. Thermal stability is inherent in the motor’s robust construction, enabling continuous operation at rated current while minimizing temperature rise. Engineers benefit from the motor’s optimized shaft detail, which resists axial and radial stresses, reducing wear and extending bearing life. The combination of precise feedback, low friction, and balanced rotor dynamics ensures consistently smooth and repeatable performance in stop-and-go processes.
Integration into complex automation systems is seamless thanks to the AKM21G-BNM22-00’s compatibility with Kollmorgen drive controllers and common industry protocols. The servo motor’s standardized NEMA mounting and electrical interface simplify mechanical assembly and wiring tasks on the plant floor. Its high torque-to-inertia ratio and reliable Comcoder feedback make it ideal for applications such as robotic manipulators, conveyor indexing, packaging machinery, and CNC tooling. By combining rugged industrial grade components with flexible drive compatibility, the AKM21G-BNM22-00 offers a versatile solution for precision-driven manufacturing processes.
