AM8121-3F21-0000
The Beckhoff AM8121-3F21-0000 motor, part of the AM Synchronous Servo Motors series by Beckhoff, is a compact, high‑precision drive designed for light‑duty industrial automation tasks. As a permanent magnet‑excited three‑phase synchronous motor, it features a rated speed of 3000 min⁻¹ and a standstill torque of 0.50 Nm, ensuring stable performance during dynamic operations. With a peak torque of 2 Nm, this servo motor handles short bursts of high load, making it ideal for applications such as precise positioning in assembly systems or small conveyor drives where space is at a premium.
In terms of technical specifications, the AM8121-3F21-0000 delivers a rated power of 0.16 kW and operates on a nominal voltage of 24…48 V DC, optimizing energy efficiency in low‑voltage environments. It draws a standstill current of 4.0 A and can manage a peak current of 17.0 A, providing a broad operational envelope for varying load conditions. The torque constant of 0.13 Nm/A enables precise torque control, while the rotor moment of inertia of 0.134 kgcm² ensures rapid acceleration and deceleration with minimal overshoot. Convection cooling simplifies installation by eliminating external cooling hardware, improving reliability in confined spaces.
Additional features of the AM8121-3F21-0000 include integrated feedback via a resolver and a single‑turn absolute encoder for high‑resolution position control. Connectivity is secured through itec® plug technology, offering robust electrical contact even in vibration-prone environments. Rated for ambient temperatures from +5…+40 °C, this servo motor maintains consistent performance across typical industrial climates. By combining compact design, efficient power utilization, and precise feedback, the Beckhoff AM8121-3F21-0000 enhances throughput, reduces downtime, and delivers exceptional stability in modern automation systems.
