Product Description

The AM8021-1B21-0000, a remarkable offering from Beckhoff's AM Servo Motor Series, is engineered as a permanent magnet-excited three-phase synchronous motor, ideal for a variety of demanding applications in automation and control.  At the heart of this motor's design is its rated power of 0.42 kW, delivering reliable performance while maintaining energy efficiency. The peak torque output of 2.68 Nm allows the AM8021-1B21-0000 to handle substantial loads, making it suitable for tasks that require both strength and precision. 

Its standstill torque of 0.50 Nm ensures that the motor remains stable during idle periods, crucial for applications needing accurate positioning. Operating at a rated speed of 8000 min⁻¹, this motor excels in dynamic environments where rapid response is critical. The convection cooling system employed helps manage the thermal conditions effectively, preventing overheating and extending the motor's operational life. This design consideration allows for continuous operation without the need for complex cooling systems, simplifying integration into various setups.

With a standstill current of 0.85 A and a peak current of 4.90 A, the AM8021-1B21-0000 ensures that it can sustain performance during high-demand scenarios while keeping power consumption in check. Its torque constant of 0.588 Nm/A indicates efficient conversion of electrical energy into mechanical output, providing consistent performance across a range of speeds. The rotor moment of inertia is measured at 0.139 kgcm², allowing for quick acceleration and responsive operation. This feature is particularly beneficial in applications requiring swift changes in direction or speed, enhancing the motor's overall flexibility.

For enhanced accuracy in positioning and speed control, the AM8021-1B21-0000 is equipped with advanced motor feedback options, including a resolver and single-turn absolute encoder. This capability enables precise monitoring and adjustments, contributing to the overall performance reliability. Connectivity is made simple with the use of itec® plug connection technology, streamlining the installation process and ensuring robust connections in demanding environments. This feature is especially valuable in applications that require quick assembly and disassembly, enhancing overall productivity.
