Woodward SA-4478 Actuator Coil Assembly

Product Brief Introduction Precision electromagnetic coil assembly, core driving component of Woodward fuel/gas electro-mechanical actuators to generate electromagnetic force for valve movement.
Tag:

Technical Specifications Defined coil resistance; high temperature resistant enameled wire winding; industrial insulation grade.

Functional Features Fast electromagnetic response, stable driving force output, excellent high temperature resistance.

Application Scenarios Woodward series actuators for gas engines and diesel engines.

Performance Parameters Stable electromagnetic characteristics within rated temperature range, low insulation aging rate.

Structural Characteristics Compact wound coil assembly with positioning frame, designed for installation inside actuator housing.

Working Principle When energized, the coil generates electromagnetic attraction to drive armature or spool movement and adjust valve opening.

Installation Requirements Install into matched actuator housing, ensure accurate positioning and firm clamping.

Usage Notes Test insulation resistance regularly; avoid long-term overcurrent operation to prevent coil burnout.
