Drive Technology: Extension of the Beckhoff AM8000 motor family
Highly dynamic servomotors cover a large performance range

Beckhoff is extending its AM8000 servomotor series in the high and low power ranges in time for the Hannover Messe 2012. The servomotors with one cable technology offer high dynamics, energy efficiency and low costs in the power range from 0.5 to 65 Nm standstill torque.

The Synchronous Servomotors from the AM8000 series have been supplemented by the AM8021 with a standstill torque of 0.5 Nm. What is special about this motor is that it can also be operated with a DC link voltage of 565 V DC. This allows, for example, actuators to be realised in machines without an additional power supply unit, since it is possible to operate at one voltage level with the other drives.  

The power range is rounded off at the top by the AM807x series. The servomotors are available in three different overall lengths: the AM8071, AM8072 and AM8073 with standstill torques of 25 Nm, 47 Nm and 65 Nm respectively. The motors with a high power range are used in particular for high-power main drives and are thus suitable, for example, for the metalworking industry. The AM807x models can be equipped with different encoder systems, backlash-free holding brakes or a shaft seal.

Altogether, the AM8000 series encompasses six different motor sizes, each with three overall lengths. The user can select a motor suitable for the respective application from a standstill torque range of 0.5 to 65 Nm.

“Hygienic Design” servomotors up to 16.7 Nm  

The stainless steel servomotors are also supplemented by a new size, AM886x, with three overall lengths: the AM8861, AM8862 and AM8863 with standstill torques of 7.75 Nm, 12 Nm and 16.7 Nm respectively. Beckhoff thus offers a universal range of servomotors for use in extreme, harsh or corrosive environments with a power range from 1 Nm to 16.7 Nm.  

One cable solution reduces material and commissioning costs  

One of the highlights of the AM8000 series is OCT (One Cable Technology). In this one cable solution the power and feedback system are combined in a standard cable. Information is transmitted reliably and free from interference via a digital interface. Since a cable and plug are omitted at both the motor and controller end, the component and commissioning costs are significantly reduced.
