- Scope
- JB/T 8670-1997 This standard is formulated based on the supporting needs of explosion-proof valve electric devices. This standard is connected and coordinated with the technical conditions of three-phase asynchronous motors for YDF2 series valve electric devices. This standard specifies the type, basic parameters and dimensions, technical requirements, test methods and inspection rules of flameproof three-phase asynchronous motors for YBDF2 series valve electric devices, as well as marking, packaging and warranty period requirements. This standard applies to flameproof three-phase asynchronous motors (hereinafter referred to as motors) for YBDF2 series valve electric devices with a 0.025~30kW synchronous speed of 1500r/min. All series of driver motors derived from this series of motors can also be implemented with reference.
