Product Description:

The AKM21C-ANS2GB-02 is a small, high precision, fast response motor. It possesses a rotor inertia of 0.0000107 kg-m² and is not affected by acceleration and deceleration speeds in high speed applications. It possesses a torque constant of 0.3 Nm/Arms and provides stable torque output for different current levels. It possesses a back EMF constant of 19.5 Vrms/kRPM and is effective in voltage to speed conversion.

These are the values to provide correct control and effective utilization of energy, ideal for servo application where response must be most even. Optimum 1.43 °C/Watt thermal resistance for highest dissipation of heat, keeping operating temperature alive and extending life. This is the measurement where motor is cooled at constant loading, reducing stress from heat in parts. The AKM21C-ANS2GB-02 is manufactured with accuracy and smooth control being the priority in applications where they are most critical. This model is especially suited for light-duty application. Here, inertia must be reduced and energy efficiency is of utmost importance. The motor is properly suited to drive in highly regulated situations and maintain consistent motion with less oscillation. Its smooth torque and its good response to fine control enable it to be suitable for being applied in coordinated drive systems. Mechanical and thermal equilibrium of the AKM21C-ANS2GB-02, having been optimized according to its design, enable it to maintain stable performance over an extended period of time. Its quality-based design enables it to operate continuously without the need for frequent maintenance.

Good-behavioral response and precise output make it a good unit for dynamic systems with fast and precise control needs. Low inertia, medium torque constant, and stable electrical properties enable it to offer better positioning accuracy. The AKM21C-ANS2GB-02 is excellent engineering for the individual who needs the application of high-accuracy motion along with effective heat management in close installations.
