Second generation integrated servo motor

15 January 2021

OFFERING HIGH-positional capability with agile, smooth, and silent motion control, Overview, has announced the launch of Artemis, a new and enhanced variant of its award-winning, direct-drive integrated servo motor.

The first product in Overview's Servotorq II series of second-generation, Integrated Servo Motors, Artemis retains all the advantages of the original Servotorq's innovative architecture, combining precision BLDC motors, advanced controllers, high-performance servos and precision rotary position encoders into integrated direct-drive positioning solutions. Artemis is reported to offers integrators significant feature enhancements and performance improvements resulting from a new motor design, current vector control and a unique new control scheme.

Delivering a maximum torque output of 3Nm, Artemis provides rapid and precise positional control, with 0.0055° repeatability and true zero-backlash. Its upgraded trajectory control properties are said to deliver exceptional servo performance resulting in a stiff and fast control loop, enabling precise trajectory tracking that is resistant to external disturbance such as wind gusts.

Artemis has been specifically developed to enable easy integration lowering costs and timescales. Integration is made easier by enhanced tuning, advanced power protection, debug and diagnostics capabilities. A new expansion connector provides functionality for future enhancements and customer-specific needs. Artemis offers near-instant start-up, removing the need for magnetic alignment and zero-point calibration and delivering robust position feedback under all operating conditions.

Typical uses for this new drive system include broadcast cameras, larger rugged CCTV camera, or any application where larger sensors need positioning with great precision, for example when under autonomous control. Artemis is directly interchangeable with Overview’s existing Atlas Integrated Servo Motor, making it particularly suitable for existing integrators looking to enhance their positioning solutions further.
