AMK Arnold Müller GmbH & Co. KG (Germany) - The new ihXT servo motors of AMK come with inverter and only what is essential for precise servo control.
With its new ihXT series, AMK is expanding its AMKASMART decentralized product family to include a full-value servo drive with a power range of 150 to 450 watts. In so doing, only the outside appearances are economical: the most compact dimensions, the elimination of expensive connectors, and cutting of the installation effort in half through hybrid cables show that it pays to concentrate on the essentials during product development.
Functionally speaking, the combination of a synchronous servo motor and servo inverter is behind the ihXT type within the AMK AMKASMART family. The power and dimensions of these compact drives are primarily tailored to tasks in packaging machines, woodworking centers, bottling systems, and assembly and handling systems. Typical applications are positioning tasks with high precision and low power consumption. Because the connector costs for low-power drives are disproportionately high, AMK is using a clever plug-in terminal connection for connection of the units in IP65.
To make the initial installation as easy and space-saving as possible, the decentralized ihXT servo drives are equipped with a hybrid cable. The whole thing is also combined with convenient looping through possibilities: the decentralized solution receives power directly from the central or decentralized supply unit.
The DC current is then looped through via the DC bus together with the EtherCAT communication over the hybrid cable from one drive to another. Star wiring of individual drives from the control cabinet is now a thing of the past. In this way, up to 40 axes can be connected in series with one supply unit. Energy efficiency, fast commissioning, and low installation costs are thus effectively combined.
