Wide speed range, from 0.05°/s up to 1000°/s (0.8 mrads/s- 17.4rad/s), and acceleration up to 3500 rads/s² enables lightning fast response to dynamic conditions without compromising smooth motion. Essential in applications where, for example, agile switching between multiple positions or trying to maintain engagement with evasive targets is critical.

The unique Servotorq technology behind our Integrated Servo Drives delivers truly silent operation, without compromise to speed or accuracy, bringing benefits to situations where covert or unobtrusive operation is required.

Overview’s Integrated Servo Drives are designed from the ground up to deliver direct-drive, zero backlash, precision, with accuracy and repeatability levels of up to 0.0055° (96 x 10^-6 rad) delivering precise positioning. Servotorq supports control of the first, second and third derivatives of position enabling exacting control and optimised motion.

Using Integrated Servo Drives is quick and easy, requiring only two connections, one for power and one for control. To assist users, a full range of integration tools, interface definitions and command manuals are readily available. Overview’s dedicated Application Engineering team are always ready and delighted to help.

Often drive solutions are advertised as zero backlash when in truth they have reduced but not removed backlash. This is not true with Overview’s Integrated Servo Drives. As the payload is mounted directly to the motor and encoder, with no intervening belts or gears, Integrated Servo Drives achieve true zero backlash. Simplifying the transmission chain also provides benefits in drive efficiency and reliability.

Integrated Servo Drives enable continuous rotation however, this results in challenges with providing power and data signals to the payload. All of Overview’s Integrated Servo Drives have central bores that can support sliprings reducing both the footprint and wiring complexity. Atlas, Artemis and Helios offer high performance slip rings including hybrid optical/copper sliprings supporting high bandwidth data transfer.

Developed to deliver agility and precision, Servotorq is the underlying hardware and firmware technology at the heart of Overview’s Integrated Servo Drives. Providing a high performance, fully integrated ‘all-in-one’ servo drive solution, Servotorq optimises Drive motion delivering rapid, precise and ultra smooth movements.

Overview’s unique Servotorq technology provides a high level of intelligence. Each Drive has a powerful onboard microprocessor hosting the digital servo, drive configuration, command interface, health monitoring and other functions. Servotorq offers a trajectory generator that understands the physics of the drive and payload, applying optimal S-curve motion profile to deliver prefect motion during every move.

Integrated Servo Drives deliver market leading low Size, Weight and Power at a highly competitive cost point. By combining a bespoke motor, drive electronics, position encoder and digital controller Integrated Servo Drives reduce the number of discrete drive components resulting in an extremely compact footprint without compromising speed and agility.
