The HYDROSPACE High Precision Servo Drive actuator series is a high efficiency DC brushless servo motor drive integrated to a zero-backlash, high precision harmonic drive speed reducer. These are designed for deep ocean operation where compact design, high output performance and high precision control is needed. The HSD series actuators features optimized three phase BDC motors to perfectly match the harmonic drive inertia, maximize efficiency and reduce noise. The harmonic drive technology provides a single pass gear train with a wide selection of reduction ratios and the technology delivers precision output positioning with no backlash. The large output bearing configuration also delivers large output load bearing performance. The actuators come is a range of sizes for various output torque needs and motor voltages. Hydrospace custom designs BDC motors to match the needed Voltage supply. All actuators are oil-filled, and pressure compensated, rated to a depth ranging from 1000-6000m.
