Simplified DO-254 Design Process...
DDC designs compact and configurable Line Replaceable Unit (LRU) motor controllers, based upon customer defined requirements, for demanding high reliability aerospace applications, including those requiring DO-254 certification. These motor control solutions are reconfigurable to meet current and future system requirements without the need for costly updates to hardware and packaging, allowing for system reuse and design flexibility, to satisfy numerous electro-mechanical actuation applications.

DDC is a premier manufacturer of high-reliability data networking, power control, motion feedback and motor controller devices for brush, three-phase brushless and induction motors, operating from 28 V to 600 V and demanding up to 20 kilowatts of power for a wide range of military and civilian aircraft. Our extensive knowledge and history of designing and fabricating MIL-STD electronic components and systems enables us to adhere to the strict manufacturing and quality control procedures needed for DO-254 certification for both military and civilian aircraft. This allows us to reduce time to market and manage technical and program risks by leveraging certifiable and proven design blocks with high technology-readiness levels. DDC is also experienced in design documentation and requirements traceability as a part of internal standard design and verification standard operating procedures.

Civil Aerospace Motor Control Applications Include: pumps, fans, valve controls, winch and cargo loading systems, vacuum generation, compressors, seat control, waste compactors and air handling systems

Example
I/O Networking, Control & Status Software

DDC can design a standard or custom interface option for your application removing the need for system modification in order to adopt a new motor controller. IO options include: ARINC 429/717, Ethernet, CANbus J1939, CANopen, MIL-STD-1553/1760, RS-232/422/485.
Motion Feedback

DDC’s experience with motion feedback devices spans over 50 years uniquely enabling DDC to support all of your motor and actuator feedback needs independent of number and type of speed and position requirements. Examples include synchro/resolver, absolute and incremental encoders, Hall sensors or sensorless operation.
EMI/EMC Conditioning

Depending on your application’s power availability, DDC can provide a complete power conversion, conditioning and power factor correction system in order to supply power for the load actuation, maintain EMI/EMC quality and conform to MIL-STD-461/1399/1275/704 as well as other power quality requirements.
Amplifier Drive with Current Control

DDC has capabilities to support a wide variety of motors with power requirements up to 20kW, and voltages ranging from 28Vdc to 600Vdc. DDC’s drives can be implemented with MOSFET, IGBT, SiC or GaN devices in order to control the motor actuation with precisely managed torque, speed and position characteristics while providing system diagnostics and prognostics parameters.
