Electric servo-actuator 11

rotarywith servo-motorAC

Overview
Compact integrated rotary actuators combine a frameless internal-rotor torque motor, harmonic drive and absolute encoder into a single actuator unit. Drive electronics are normally external to allow flexible integration and high-precision motion control. These units are engineered for applications demanding high torque density, precise positioning and minimal installation footprint.

Features

• High torque output: Designed to deliver significant torque at low speed to meet machine-load requirements across sizes.
• Compact integrated design: Frameless motor architecture embeds directly in the actuator to reduce overall envelope and simplify mechanical integration.
• Precision control capability: High-resolution absolute encoders enable sub-micron/arcsecond-level positioning and smooth settling for precision stages.
• Low-inertia dynamic response: Lightweight rotor and low-friction construction improve acceleration response and reduce motion lag.
