Importance and Core Requirements of Grounding for Xi'an SIMO Motors
Grounding is one of the core safety requirements for motor products, as it not only ensures the safe operation of the motor but also directly impacts the safety of operators and associated equipment. SIMO Motors strictly complies with two key standards-GB14711 and GB755-and enforces rigorous regulations for motor grounding. However, due to differences in understanding or other factors, some motor manufacturers still fall short in grounding practices. In contrast, SIMO Motors implements stringent control processes from supplier selection to production to guarantee the safety of motor grounding.
Importance of Grounding for Xi'an SIMO Motors
1.Personnel Safety Protection
Effective grounding diverts leakage current to the earth, preventing electric shock accidents and ensuring operator safety.
2.Equipment Safety Assurance
Prevents abnormal currents from damaging internal components, extending the motor's service life.
3.System Stability
Reduces electromagnetic interference on peripheral equipment, ensuring overall industrial system reliability.
Core Requirements for Xi'an SIMO Motor Grounding
1.Compliance with Standards
Strict adherence to GB14711 (General Safety Requirements for Small and Medium Rotating Machinery ) and GB755 (Rotating Electrical Machines-Rating and Performance ) , ensuring alignment with national standards.
2.Grounding Device Design
Permanent, low-resistance (≤0.1Ω) electrical connection between the motor frame and grounding device.
Dedicated corrosion-resistant grounding terminals (e.g., stainless steel or plated metal) separate from other functional components.
3.Connection and Material Specifications
Grounding wires must use copper or aluminum with standardized diameters; cold crimping is preferred over soldering or twisting.
Ensure direct metal-to-metal contact by penetrating non-conductive coatings (e.g., paint) in the grounding path.
4.Production and Inspection Control
Rigorous quality control from supplier selection to manufacturing, ensuring materials and processes meet specifications.
Pre-delivery grounding resistance testing (≤0.1Ω) using professional instruments, followed by periodic maintenance checks.
5.Special Scenarios
Long-lead motors must include factory-installed grounding wires; standard motors require clear grounding symbols and installation guidance.
Modular motors must verify reliable inter-component grounding via copper braided straps.
