twx servo motors Overview

TorqueWire® TWX integrated servo motors, are complete self sufficient servo axis building blocks which allow the design, integration and operation of large multi axis systems with minimum hardware and surprising ease.

TWX series system consists of an advanced, high performance rare earth brushless servo motor.

The device incorporate a DSP based, high voltage interpolating servo drive, and a single or multi turn absolute encoder, all assembled in a very compact IP 65 frame, with no cables or junctions between motor and drive.

The performance of TorqueWire® Tecnology originates from the advanced design of both motor and drives. The motor parts take advantage of a novel, highly optimized winding design, along with new magnetic materials and a special winding technique, all of which result in a servo motor with about 60% of the size of a conventional integrated servo motor design.

TWX series is particularly innovative in the electromagnetic compatibility approach.
The drive is designed and validated for high level vibration and wide temperature range.
The design is free from electrolythic capacitors, enabling long life even in temperature.

The control is performed via a EtherCAT or CAN fieldbus, linking groups of motors on a single bus system.
Power is supplied from a common DC bus, and braking energy from any drive is intrinsically recycled on other axis.
Such advantage is invested in both temperature rise derating and space for the drive.
In this way, TorqueWire motors, including the drive, are smaller than comparable motors with similar rating.
