Overview
The MKS HV777A+ Digital Ultra Torque High Voltage Servo Motor is part of the MKS HV high voltage servo series, designed to operate at high voltage and low current while delivering high torque per unit weight. With a control data rate of 333 Hz, this high voltage servo provides agile, fast response and precise control. A full aluminum case, titanium metal alloy gear train, dual ball bearing output shaft, and overload protection support low noise, durability, and long service life.
Key Features
- Digital high voltage servo motor with ultra high torque output.
- Full aluminum case for improved rigidity and heat dissipation.
- Titanium metal alloy gears for strength and wear resistance.
- Dual ball bearing output shaft for smoother operation and reduced friction.
- High working frequency (333 Hz) for fast, precise control response.
- Wide operating voltage range from 6.0 V to 8.4 V DC.
- Very small dead band (0.0008 ms) for accurate positioning.
- Japanese-made coreless motor and FET driver for efficient power delivery.
- Designed for applications requiring high torque per unit weight at elevated voltage.
