Product overview
The EMAX ES9055II High Voltage Magnetic Encoder Servo is a brushed digital actuator for heavy-duty fixed-wing control surfaces, high-load RC helicopters, robotic joints and rotating mechanisms. Its physical architecture combines all-metal gears and housing with non-contact magnetic encoder feedback. The metal construction supports impact and sustained loads, while the encoder maintains stable centering during vibration and long operating cycles. The product is a servo component for installation within a larger aircraft or mechanism.
Integration centers on an approximately 40 × 20 × 38.5mm body, a net weight of 78.5 ±1g, a JR connector and a 23T output spline. Its PWM range is 500–2500μs, with 180° ±2° rotation and support for full-range 360° positional control. Power must fall within 6.0–8.4V. Speed and stall torque depend on voltage: at 8.4V they reach 0.12 sec/60° and 35 kgf·cm, respectively. Approximate stall current is 4.0–5.5A as a typical reference range.
