Product Description:
The AMI8121-4100-0F11 is a synchronous servo motor manufactured by Beckhoff. It can handle any motion duty up to 400 W. It incorporates a servo drive and is suitable for tiny automation needs. This servo unit is equipped with flange code F2 and has a 58 mm mounting base.
The Beckhoff's AMI8121-4100-0F11 produces a maximum torque of 0.45 Nm and a standstill torque of 0.48 Nm. It generates a rated torque of 0.45 Nm and a stall torque of 0.48 Nm. When it accelerates it produces the maximum torque of 1.89 Nm. The motor has a maximum speed of 3000 RPM and produces 0.141 kW. The shaft is 9 k6 wide and 20 mm in diameter at the ends. The motor is barely one inch long so it may be fitted in a small space. The rotor's moment of inertia is 0.139 kg·cm² allowing for rapid dynamic response. For stable operation it requires a nominal voltage of 24 to 48 V DC. The built-in EtherCAT system bus enables accurate real-time data transmission and reception. It is compatible with numerous devices and supports both MDP and DS402 drive settings. Basic safety features are Safe Torque Off and Safe Stop 1. It satisfies EN ISO 13849-1:2015 standards and can achieve Cat 4 PL e. In terms of practical safety it satisfies EN 61800-5-2:2017 standards.
The Beckhoff's AMI8121-4100-0F11 servo motor provides reliable and compact performance. This servo motor supports both M12 l-coded and M8 screw-type connectors. The M8 sockets come in three- and four-pin a-coded varieties. The temperature range for use is +5°C to +40°C. It has CE, cURus, and EAC approvals depending on how TwinSAFE is configured. Its certified safety functionalities and certifications guarantee machine-level compliance. The AMI8121-4100-0F11 is suitable for complex motion tasks in decentralized automation.
Frequently Asked Questions about AMI8121-4100-0F11:
