The technical conditions of three-phase asynchronous motors for YDF2 series valve electric devices are based on the YDF series motors and revised according to user requirements. The YDF2 series is divided into two designs, type A and type B, according to different rotational torques. Type A is suitable for matching with general-purpose valve motor devices. Type B is suitable for matching valve electric devices that require high stall torque. This standard will replace JB2195-77 "Technical Conditions for Three-Phase Asynchronous Motors for Electric Valves" after it comes into effect. This standard is formulated based on the needs of valve electric devices. This standard is under the jurisdiction of the National Rotating Electrical Machine Standardization Technical Committee. This standard was drafted by: Shanghai Electrical Apparatus Research Institute, Hulan Valve Motor Guangdong. The quasi-drafters of this document are Li Wenzheng, Huang Yaohui, Zhu Tiecheng, Wang Yuanli, and Chang Shengcheng.1 Scope
