DC Rotary Actuator Repair & Overhaul
FAA & EASA certified dc rotary actuator repair and overhaul.
About the DC Rotary Actuator
A DC rotary actuator converts electrical power into rotary motion to position a load through a defined angular travel, serving within the aircraft actuation system as a motorized actuator for moving panels, valves, or control surfaces. It typically integrates a DC motor, a reduction gear train, and an output drive, often with limit switches or a position feedback element to define end stops. In service it drives mechanisms requiring repeatable, controlled rotation. Common degradation modes include brush and commutator wear, winding insulation breakdown, gear-tooth wear and backlash, bearing spalling, and contamination or corrosion of internal contacts. Limit-switch maladjustment, output-shaft seal leakage, and loss of holding torque also drive overhaul, with electrical continuity and torque-versus-travel checks confirming serviceability.
Our DC Rotary Actuator Repair Capability
QTC repairs and overhauls dc rotary actuator components to the original manufacturer's specifications under our FAA and EASA Part 145 approvals. Our engineers — including former OEM actuation specialists — perform teardown, inspection, cleaning, component replacement, functional and leak testing, and certification, and develop repairs for rejected and beyond-economic-repair (BER) hardware.
