Product Description:
Beckhoff manufactures the AM8072-0T21-0000. The electromagnetic design of the AM8072-0T21-0000, a high-performance permanent magnet-excited three-phase synchronous servo motor, is unique. The three-phase AC current from the stator creates a rotating magnetic field that interacts with the permanent magnets in the rotor. Through this contact, a synchronous operation is generated where the rotor speed matches exactly and consistently the frequency of the supplied AC current. In industrial automation, where precision and reproducibility are key, this is crucial. By using permanent magnets instead of rotor field windings, energy losses are reduced and overall efficiency is increased.
Because of its flexibility and ability to run over a nominal voltage range of 100–480 V AC, the AM8072-0T21-0000 is compatible with a wide range of industrial power supplies. This flexibility eliminates the need for large voltage adaptation and allows for easy integration into various regional power grids. The motor design complies with international standards, so it’s suitable for various industrial applications. With a rated torque of 13.0 Nm and peak torque of 169 Nm, it’s powerful enough to run in high-demand transient and continuous operation. Its ability to hold position in critical situations like precise motion indexing and robotic arm control is also supported by its 50.0 Nm standstill torque.
The AM8072-0T21-0000 uses convection cooling, a passive method that uses the air’s natural flow to dissipate the heat generated during motor operation to control its temperature. This design makes the motor quieter, more energy efficient, and more reliable by eliminating the need for external cooling systems. To ensure stable operation in common industrial environments, the motor is designed to operate between 5°C and 40°C. The motor has advanced feedback systems that provide exact position and speed feedback for very precise control. These systems include options like a resolver and various encoder types. The motor’s low rotor moment of inertia (92.2 kg·cm²) allows for fast acceleration and deceleration, which is necessary for dynamic applications that require precise and fast motion, and its quick-connect M40 speedtec® connector system makes installation and maintenance easy. This motor is perfect for advanced industrial automation systems with 4.08 kW power and 1.33 Nm/A torque constant.
