Product Description:

The AM8051-1E20-0000 Servo Motor from Beckhoff is a permanent magnet-excited three-phase synchronous motor. It is specialized for industrial automation systems. The nominal voltage for this motor is 400 to 480 V AC, and its main output power is rated at about 1.20 kW. The motor reaches 17.7 Nm of torque magnitude at a current of 12.1 A, making it helpful for challenging movements.

The AM8051-1E20-0000 servo motor hits its rated speed of 2500 RPM and gives a maximum peak torque of 4.8 Nm, using a standstill current of 2.7 A. A rated torque constant is given as 1.77 Nm per Ampere. The AM8051-1E20-0000 servo motor’s rotor inertia is close to 2.25 kg·cm², which makes the motion it controls both stable and repeatable. It comes with a shaft that has a feather key for a strong mechanical link. The diameter of the shaft is 24 mm, with a tolerance class k6, and the free shaft end reaches 50 mm. F5 is the type of flange, with a usual size of 104 millimeters. An absolute encoder that supports several directions is part of the feedback and works using One Cable Technology (OCT). Consequently, there is less cabling involved, which helps with how securely the motor can be mounted.

The AM8051-1E20-0000 servo motor does not come with a holding brake and uses self-cooling, requiring no external fan. Using the encoder gives the controller extra control accuracy because it supplies information on the motor’s exact position multiple times. This particular servo motor is perfect for adding automation in small and closed-loop systems. It is developed for systems where constant torque, accurate positioning, and limited need for maintenance are important. This servo motor is designed for working with several motion control platforms.
