In the actual production process, some long lead three-phase asynchronous motors, the vast majority of the ground wire is provided by the manufacturer; Grounding is a very critical safety protection measure in motor products. Here is a simple understanding of the problem of motor grounding with Senli Motor Xiaobian.

       1.The motor must have a protective grounding device that meets the requirements, and there should be a permanent, reliable and good electrical connection between the frame and the protective grounding device. When the motor moves on the base of the equipment, the protective grounding conductor should still be reliably connected.

       2.If a terminal is used to connect the ground conductor, the terminal must meet specific requirements. The connection of the protective grounding terminal must be securely locked to prevent accidental rotation and reduce the electrical gap and creepage distance. Do not loosen the terminal without tools.

       3.Three-phase differential motorThe protective grounding terminal is not used as the protective grounding at the same time.

       4.The materials used to protect the grounding conductor and the grounding terminal and their connection devices shall be compatible, resistant to electrical corrosion and electrically good conductors. If ferrous metal is used, it should be electroplated or other effective measures to prevent rust.

       5.The protective grounding conductor should have enough toughness, should be able to withstand the vibration stress of the motor, and it should have appropriate protection measures to prevent danger during the use and installation of the motor.

       6.The protective ground connection should be able to ensure true penetration of non-conductive coating layers such as paint. The connection mode may be cold pressing or other equivalent means, and no articulation and solder only shall be used.
