Product Description

The AM8031-1D20-0000 is a Beckhoff motor that conforms to several international standards, such as the cURUs, CE, UKCA, and EAC. It features a permanent magnet on its rotor, and it exhibits a set of impressive features, common for all Beckhoff’s AM8 servomotor product lines. With a flange measurement of 72 mm and a weight of 1.8 kilograms, the AM8031-1D20-0000 supports various installation methods and orientations, such as IM B5, IM V3, and IM V1. During operation, the machine converts alternating-current electricity into mechanical output by means of electromagnetic induction. Whenever AC current flows through a motor, the stator provides a moving magnetic field, which in turn causes the magnet-loaded rotor to turn.

Specifically, the AM8031-1D20-0000 features brushless construction, and it runs at synchronous speed. Synchronous motors, as opposed to asynchronous motors, do not have a slip speed and run in sync with the speed of the moving magnetic field. At the nominal voltage supply of 400 V, the AM8031-1D20-0000 provides a nominal current, torque, and power of 1.9 A, 1.33 Nm, and 0.84 kW, respectively. At this operating point, the shaft revolves at an impressive rate of 6,000 cycles per minute.

The AM8031-1D20-0000 has a torque constant of 0.71 Nm/A. This parameter describes the sensitivity of the output torque with respect to the input current. Changing the input current by one ampere produces a relative change in the motor’s output torque by 0.71 Nm. Since the AM8031-1D20-0000 employs no surface fans or liquid cooling system, the machine cools naturally via convection. During operation, a thermal contact sensor detects the machine’s winding temperature to prevent thermal-induced damages. The AM8031-1D20-0000 has a shaft feather key and an accurate OCT multi-turn feedback mechanism.
