Product Description:

The Beckhoff AM8021-0B11-0000 is very carefully designed as one of the members of the AM Servo Motor Series. This type of motor is a permanent magnet-excited three-phase synchronous motor, with a nominal AC voltage range of 100 to 480 V, which is used in precision-motion applications. The electric motor provides a rated power output of 0.42 kW, and rotates at 8000 min-1, making it suitable for applications that require rapid operation in the industrial settings.

Its main characteristic is peak torque of 2.68 Nm, which provides high efficiency in the presence of increased loads. This is supported by the motor’s standstill torque of 0.50 Nm, which enables the motor to operate smoothly during time of no rotation. The AM8021-0B11-0000 does all this while incorporating convection thermal management that is a passive mode of cooling but which increases system reliability through avoiding the use of flammable and complex active cooling systems. Regarding control and feedback this motor is versatile with a resolver and single turn or multi turn absolute encoder variants, it provides high positional accuracy for key applications. It has torque constant of 0.588 Nm/A which implies that it can deliver a constant torque corresponding to the current supplied.

This motor is constructed to be robust for industrial applications; it has high quality materials and the rotor moment of inertia is 0.139 kgcm² to ensure mechanical stability at high speed. The connection technology of the motor is the Itec® plug that provides safe electrical connections that are not likely to fail under demanding industrial operations. This motor is safe, efficient and has three certifications namely CE, cURus, as well as EAC. Ideally suited for many indoor applications across numerous industries that require high-performance servo motors with reliable international safety approvals, it is designed to perform in a controlled ambient temperature of + 5 °C to + 40 °C.
