AM8561-0G21-0000 by Beckhoff

The AM8561-0G21-0000 servo motor from Beckhoff is an advanced solution in the AM Synchronous Servo Motors series designed for high-precision industrial automation applications. This permanent magnet-excited three-phase synchronous motor delivers a rated power of 1.90 kW across a nominal voltage range of 100 to 480 V AC and provides a standstill torque of 12.8 Nm. It features rugged M23 speedtec® plug connection technology for rapid installation and maintenance. The motor is classified under the AM8xxx Synchronous Servomotors product family and utilizes an OCT multi-turn feedback type for accurate position control. A flange size of 142 mm and smooth shaft design ensure compatibility with standard mounting interfaces while maintaining compact overall dimensions.

Performance characteristics are driven by a rated torque of 12.1 Nm and a peak torque of 37.1 Nm, supported by a torque constant of 3.19 Nm/A and a peak current of 13.9 A. The rotor’s moment of inertia, 48.2 kgcm², is optimized for responsive acceleration profiles, and the static friction torque of 0.045 Nm minimizes unintended motion at rest. Convection cooling maintains thermal stability under continuous operation, while the 24 V holding brake draws just 0.72 A (24 W) to ensure secure stoppage under load. The motor’s 10-pole configuration contributes to smooth torque delivery and low cogging for high-precision positioning. An increased mass moment of inertia series type design balances dynamic response with mechanical stability in demanding cycle times.

Engineered for reliability in harsh environments, the AM8561-0G21-0000 carries an IP65 protection rating on its standard housing and shaft bushing, with an optional IP54 shaft feed-through version for specialized configurations. The acrylic powder-coated RAL 7016 finish enhances corrosion resistance and identification within control cabinets. Compliance with CE, cURus, EAC approvals/markings ensures seamless integration into global automation systems. The rotatable angular connector or terminal box connection and IEC/DIN-compliant flange fit class J6, tolerance class N enable straightforward mechanical coupling. This motor excels in robotics, packaging machinery, CNC equipment, and general industrial automation where precision, durability, and ease of integration are paramount.
