Grain-Oriented vs Non-Oriented Silicon Steel: Which for EV Motors? Most buyers confuse grain-oriented and non-oriented silicon steel for EV motor production. Here is the clear distinction:   Grain-Oriented Silicon Steel (CRGO): Designed only for single-direction magnetic flux transformers. Not applicable for EV stators and rotors.   Non-Oriented Silicon Steel (NOES): Features uniform mul...

What is Compound Die Stamping for Motor Core Compound die stamping completes the full shape of stator or rotor lamination in one single stroke. It is a traditional and cost-effective process for small batch orders and prototype sampling.   Advantages - Low mold cost, suitable for new product development. - Fast proofing speed, 3–5 days for custom samples. - High single-piece precision f...

  Core Principle: Excessive Contact Resistance Terminal overheating is fundamentally caused by abnormally high contact resistance. According to Joule’s law, high resistance generates massive heat when current passes through. Once the terminal contact surface fails to fit tightly, resistance rises sharply, forming a vicious cycle: heat accumulation → increased resistance → more...

Main Causes of Terminal Overheating and Blackening 1. Unqualified Contact & Loose Installation Loose crimping, uneven torque and assembly gaps reduce the effective contact area of terminals. Based on the I²R heating principle, local high resistance generates intense heat, scorching metal surfaces and forming permanent black carbonized marks. Excessive crimping also causes micro-cracks and...

Key Precision Influences of High-Speed Terminal Stamping High-speed stamping usually runs at 1000–6000 strokes per minute. The core precision deviations mainly come from dynamic operation rather than the process itself:   - Equipment Vibration & Position Deviation: Long-term high-frequency impact causes slight body vibration and slider deflection, resulting in step distance errors a...
