Technical Specifications Supply: 24 V DC ±10%; control input: 4–20 mA; output torque: 8 N·m nominal; stroke: 90°; full stroke time: 100 ms; position feedback: integrated LVDT; operating temp: -40 °C to +85 °C; IP65.
Functional Features Brushless DC drive; closed-loop position control; zero/span calibration; overload protection; vibration-resistant design.
Application Scenarios Small engine fuel control, gas engine throttle actuation, generator governor actuation, small valve positioning.
Performance Parameters Position repeatability: ±0.1% of stroke; linearity: ±0.5% FSO; step response: < 100 ms.
Material Composition Die-cast aluminum housing; brushless DC motor; planetary gear train; LVDT position sensor; steel output shaft.
Structural Characteristics Rotary output shaft with keyway; side mounting flange; integrated electronics; sealed cable entry.
Working Principle Receives 4–20 mA position command, drives brushless motor via gear train, and uses internal LVDT feedback for closed-loop position control.
Installation Requirements Mount via flange to engine; couple output shaft to linkage; connect control cable; calibrate zero and span.
Usage Notes Avoid excessive radial loads on shaft; inspect seals periodically; calibrate position at operating temperature.
