3Simplified 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
