DATASHEET LETO TM "Servotorq " Integrated Servo Motor TM FEATURES *All-In-One, Precision, Direct-Drive Motion *Class-Leading Positional Accuracy and Repeatability *Ultra Smooth and Silent *Zero Backlash *Low Size, Weight and Power *0.09Nm Output Torque *Exceptional Repeatability Compact, Smooth and Accurate Motion for Advanced Sensor Positioning Part of the Servotorq series of Integrated Servo Motors and designed for applications requiring exceptional positional accuracy and repeatability, Leto delivers ultra-smooth, fast, silent and precise motion in a compact, standalone package. Its small footprint makes it ideal for integration in to a wide variety of sensor position applications including video conferencing cameras and CCTV PTZ applications utilising heavier 4K camera modules. Fully Integrated Solution Eliminating the need for a separate motor, servo controller and cabling, Leto combines a BLDC motor, advanced control electronics, a high-performance servo and a precision rotary position encoder into a fully integrated, direct-drive, motion control solution. Technical Specification Part Number Electrical Specifications Nominal Voltage Current at max torque at 24v Initialisation Current Idle, no load, current Position command & readback resolution Maximum speed Min. non-zero speed Mechanical Specifications Weight Easy Integration Dimensions (LxWxH) Leto has been designed with simplicity for the integrator in mind and supported by its simple connectivity via a standard IC interface and supply voltage, significantly reduces product development effort and overall system costs, which means that time-to-market and production efficiencies can be significantly improved for the integrator. Leto's compact design, just 65mm at its widest point, also supports integrators in the design of simpler and more attractive end products. Rotor moment of inertia Stall torque Moving Torque (at 360s) Perpendicularity Maximum radial load Best in Class Performance Leto has a wide dynamic speed range of between 0.05s and 720s. Integrated drive control electronics and software provide closed-loop servo control, delivering velocity and acceleration control. Leto also provides rapid and precise positional control, with 0.0055 repeatability and zero backlash and is robust to external dynamic disturbances, especially impulses and vibrations.
