BECKHOFF Automation has extended its AM8000 servomotors range with the addition of a new flange size F1 featuring a 40mm edge length.
Three overall lengths available in the AM8000 series cover a torque range from 0.22 to 0.55 Nm, enabling highly dynamic drive solutions to be implemented in minimised space requirements.
Offering a low rotor moment of inertia as well as quadruple overload capacity to meet the highest requirements for motion dynamics even in the smallest of installation spaces, the new AM801x and AM811x servomotors are ideal for applications with fast cycle changes. The two series differ primarily in their rated voltage.
An extremely compact and economical servo system can be implemented by combining the AM811x motors with the EL7201-0010 and EL7211-0010 servomotor terminals, with 2.8 ARMS and up to 4.5 ARMS respectively, at 50 V DC. The AX5000 EtherCAT servo drive (1/2 canal, up to 3 A) can be used to control the AM801x servomotors, which are designed for 230 V AC.
The motors are available optionally with backlash-free permanent magnet holding brake or feather key groove. The motors are also equipped with an absolute encoder and One Cable Technology (OCT) to maximise motor performance in a compact size. The OCT enables transmission of motor supply and position feedback signal via just one cable, significantly reducing the costs for components and installation.
The multi-turn absolute encoder integrated in the AM801x and AM811x motors and available on request makes known the absolute position of the drive when switching the axis on, eliminating the need for a homing function and allowing the system to be started without reference drives to the end positions. Additionally, it helps determine the position of the axis as well as the current displacement speed. The drive position is stored in an EEPROM without battery buffering. All these features make the new motor ideally suited to feed and traversing axes, since limit switches and additional encoders are not required.
Key features of Beckhoff’s new compact servomotors also include electronic type plate containing mechanically and electronically relevant data such as serial number, type and manufacturer’s data for reliable and rapid identification in plant networks; integrated error memory for on-line diagnostics; AX5805 TwinSAFE Option Card to allow safe drive functions to be implemented easily even in the smallest of installation spaces, enabling traversing and feed axes to be switched off safely, as well as programming including safe motion functions to be done according to EN ISO 13849-1 to PLe; motors allowed to be switched torque-free and monitored in terms of speed, position and direction of rotation, helping traversing and feed axes to also be integrated into the TwinCAT system, which considerably increases the availability of the entire machine.
