Product Description:

The high-performance synchronous servo motor AKM21C-BNPNC-00 designed for demanding motion control tasks by the Kollmorgen. This motor appears as part of the trusted AKM series that delivers excellent power in a compact form factor suited for situations where space is limited, but precision and responsiveness are required.

This motor is engineered to operate at up to 8000 RPM at 230VAC and it can be used for high speed performance required by automation systems, robotic systems, and precision manufacturing setups. With a rated torque of 0.39 Nm and peak torque of 1.47Nm, the motor is capable of dealing with dynamic load, and short range high force for those periodic occurrences. It also has a standstill torque of 0.48 Nm for steady performance while the motor isn't turning, bettering the stability in control systems.

The motor is constructed using 6 pole design which ensures efficiency and smooth running at different loading conditions. It draws a maximum of 6.3 Amps with torque constant of 0.3 Nm/A to ensure consistent power output. It also guarantees reliable electrical performance under different operating conditions with the winding resistance of 13 ohms and winding inductance of 19 mH.

The AKM21C-BNPNC-00 weighs only 0.82 kg and is lightweight and durable. It is capable of supporting a load to 60 N at 5000 RPM and is therefore suitable for use in mechanically demanding environments. With 76.1 mm x 95.4 mm x 129.5 mm (with brake) dimensions, it has a compact size and can be installed in a space constrained system. This motor gives OEMs and engineers high speed capability, precision torque output, and reliable performance in a servo motor that is perfect for dynamic and space sensitive applications.
