Scope: This document specifies the general requirements and performance requirements for power motors of electric aircraft electric propulsion systems. This document applies to power motors used in electric aircraft electric propulsion systems with a DC bus voltage not exceeding 1500 V and a rated power not exceeding 200 kW; Main technical content: Electric aircraft electric propulsion systems use high-reliability, high-torque/power density, and high-efficiency motors as power sources, directly or indirectly driving propellers, ducted fans, and other devices to provide or generate thrust/lift for aircraft, improving aircraft flight performance while reducing fuel consumption and pollution emissions. Due to the significant differences in operating conditions, environments, and design requirements between electric aircraft and traditional industrial motors, as well as the distinct characteristics and design of motors and engines, it is necessary to standardize the technical requirements for power motors of electric aircraft electric propulsion systems in China. The drafting group conducted a review and analysis of relevant standards for power motors of electric propulsion systems at home and abroad, surveyed domestic electric aircraft main engine manufacturers and power motor suppliers, and combined with the development needs of China's electric aircraft and power motor industries, particularly referring to mature national standards in the electric vehicle industry, to propose technical specifications for power motors of electric aircraft electric propulsion systems that adapt to China's industrial development level. This document has been continuously coordinated, revised repeatedly, and validated to scientifically and reasonably standardize the general requirements and performance requirements of power motors, and was finalized after soliciting opinions from industry experts and regulatory authorities. This document applies to the R&D, production, installation, and
