Product Description
The Beckhoff AM8021-0B21-0000 is an innovative Servo motor in the AM Servo Motor series that has a feature of a permanent magnet-excited, three-phase synchronous motor. The high-speed applications of this model are designed to ensure maximum performance with a rated speed of 8000 min⁻¹, to cater for fast moving applications that require accuracy and precision. This servo motor operates from a broad nominal voltage input range of 100V AC to 480V AC and is suitable for many industrial applications. Its peak torque of 2.68 Nm makes it possible for it to handle load requirements and any sudden change of speed without straining. Furthermore, Motor standstill torque is 0.50 Nm so that it maintains position without movement as well.
Regarding the physical layer, the AM8021-0B21-0000 is designed with protection IP65, which means that it is protected against contact with dust and water. Such a high degree of protection makes it possible for the motor to work under difficult circumstances to further enhance their sturdiness and durability. Ventilation is through convection mode, making it easier to maintain the operating temperatures without the need of complicated active cooling systems. This feature helps to make the motor durable, so it will work non-stop when there will be a need for it to run for many hours
Regarding feedback and control, the motor is suitable for many feedback devices, such as a resolver , single turn absolute encoder with 18 bits resolution, which makes position as well as speed control. The torque constant of 0.588 Nm/A therefore allows easy torque output proportional to input current hence controlling with great accuracy for motion. The connection technology applied in this motor is the Itec® plug which provides easy connection of the motor to the control system. Also, the AM8021-0B21-0000 complies with several international standards; it has CE, cURus and EAC approvals which ensures that the product complies with safety and performance requirements. This servo motor has a stand still current of 0.85A and a peak current of 4.90A and is capable of delivering optimal performance in many applications. The moment of inertia of its rotor is 0.139 kgcm² which contributes to the mechanical rigidity and control and maneuverability during operational activities.
