Feedback and power in a single cable

Feedback and power in a single cable With the introduction of the new AM8000 high-performance servomotor series, Beckhoff now offers a complete automation system consisting of PC-based controllers, I/O, Drives and motors - completely from the company\'s own development and production. In combination with servo drives from the AX series, to which the AM8000 series is perfectly matched with regard to power rating and windings, Beckhoff can fulfil customer requests even more flexibly.  

The AM8000 series encompasses six different motor sizes, each with two or three optional overall lengths, so that the widest possible torque range is covered seamlessly with overlaps. The user can select a motor suitable for universal use from a stall torque range of 0.9 to 65Nm.  The sophisticated rotor and stator technology represent the actual basis for the new servomotor.

Among other things, the modern salient pole winding technology is used in the motor, which enables an even higher slot fill factor. Small end turns in conjunction with a fully encapsulated stator provide  robustness and excellent thermal management. Through the optimised design and use of high-quality materials, it has been possible to increase AM8000 energy efficiency by more than 10% compared to conventional servomotors.

With the new single-cable technology from Beckhoff, which gets by without an additional feedback cable, power and process data are transmitted in one standard motor cable. The encoder data, rotor position, multi-turn information and the status of the thermal conditions in the motor are transmitted reliably and free from interference via a digital interface. This results in significant cost savings, since plug connectors and cables are eliminated at both the motor and the controller ends.
