Product Description:

Beckhoff International’s AM8032-0E20-0000 is a steadfast AC machine designed by Rexroth to convert electric energy into mechanical energy. AC machines that convert electricity to mechanical energy are called motors. AC motors, in general, come in different types, but their main working principle depends on electromagnetic induction. Whenever an alternating current flows through the machine’s stator, a changing magnetic field is induced, which then allows the rotor equipped with a permanent magnet to move. AC motors that run at a speed equal to that of the induced magnetic field are called synchronous motors. The AM8032-0E20-0000 is a three-phase sync motor under the AM servo series line by Beckhoff.

When the AM8032-0E20-0000’s terminal is excited by a 400 V supply voltage, the motor’s shaft runs at a rated speed of 6000 rpm. With this consistent speed, the machine achieves the following rated parameters at its output: 2.2 Nm and 1.38 kW. At this operating point, the current flowing through the motor is 2.75 A. The torque, power, and speed of the motor are related based on one equation. Given any two values among these three, the missing parameter may be derived. Using the formula: (2*pi*N*T)/60 = P, where N is the speed, T is the torque, and P is the output power. This formula is useful for computations and estimations at different operating points.

The AM8032-0E20-0000 has a multi-turn absolute encoder that comes conveniently in one cable technology (OCT). With this encoder, the AM8032-0E20-0000 may communicate with other devices to initiate motor monitoring and parameter control. For seamless compatibility, it is recommended to use Beckhoff’s dedicated drives and technologies for controlling AM servo motors, such as the AM8032-0E20-0000.
