T/AOPA 0062-2024 Electric aircraft electric propulsion system power motor controller technical specification

Scope

Scope: This document specifies the general requirements and performance requirements for power motor controllers in electric propulsion systems with a DC input voltage not exceeding 1500 V and a power not exceeding 200 kW. This document is applicable to the design, production, and airworthiness certification of power motor controllers for electric aircraft propulsion systems; Main technical content: New energy electric aircraft are environmentally friendly and highly energy-efficient, providing a promising technological path for green aviation. Both domestically and internationally, the research and development of electric aircraft are very active. Due to the design characteristics of electric aircraft, their power systems and other components differ significantly from those of aircraft using fuel engines. The electric propulsion system is the core of electric aircraft, consisting of motors, controllers, and related devices, which provide lift/thrust for electric aircraft. The performance and application of electric aircraft mainly depend on their electric propulsion systems. Power motor controllers are onboard equipment with small size, light weight, and high power density, and they must meet the requirements of harsh environments such as high voltage, high power, and high altitude to be installed and used. High-power density power motor controllers involve electronic components such as high voltage and high current, and the civil aviation authorities have not yet developed technical standards and specifications specifically for motor controller equipment to ensure that the safety performance indicators meet the requirements. Due to the particularities of the operation, operating rules, and environmental requirements of power motor controllers in electric aircraft, which differ significantly from those of industrial motor controllers, it is necessary to formulate corresponding provisions for the production, technical requirements, and test contents of motor control
