In today’s electrification era, high-speed motors are the backbone of advanced applications—from electric vehicles (электромобили) and drones to robotics and industrial automation. At the core of these motors lies a critical material: silicon steel.
Selecting the right grade of silicon steel directly impacts the motor’s efficiency, thermal stability, weight, and power density. В этой статье, we’ll explore how engineers and sourcing managers can choose the optimal silicon steel for high-speed motors, and how reliable suppliers like Jiaxiao MTC can help meet performance and supply chain requirements.
? What Is Silicon Steel?
Silicon steel, также известный как электротехническая сталь или lamination steel, is a soft magnetic alloy made primarily from iron and silicon. It is engineered to deliver low core loss, high permeability, и excellent magnetic efficiency, which are crucial for motors that operate at high rotational speeds and switching frequencies.
There are two major types:
- Grain-Oriented Electrical Steel (ИДЕТ): Best suited for transformers.
- Неэлементная электрическая сталь (НЕТ): Ideal for rotating equipment like high-speed motors and EV drives.
⚙️ Key Selection Criteria for High-Speed Motor Silicon Steel
When selecting silicon steel for high-speed applications (10,000+ RPM), consider the following factors:
1. Low Core Loss at High Frequency
Core loss increases dramatically at high operating frequencies. Look for silicon steel grades with low hysteresis and eddy current loss in the 400Hz–1,000Hz range.
✅ Recommended: Grades like 20XW1300 or 20XWH1200
2. Ultra-Thin Gauge for Reduced Eddy Currents
Thinner laminations minimize eddy currents, making the steel more efficient. High-speed motors benefit from ultra-thin materials (0.08mm–0.15mm) to maintain performance while reducing heat generation.
✅ Jiaxiao MTC offers 0.08mm, 0.1мм, and 0.15mm gauges in mass production
3. Excellent Magnetic Saturation
To ensure the motor delivers high torque in compact designs, the silicon steel should have a high magnetic flux density. This allows motors to run faster without saturation losses.
4. High Mechanical Strength
High-speed rotors experience extreme centrifugal forces. The silicon steel should possess good tensile strength и low anisotropy, ensuring mechanical durability and dimensional stability.
5. Consistent Quality and Tight Tolerances
Silicon steel must be cold-rolled and annealed to precise standards. Tolerances in thickness and flatness affect lamination stacking and ultimately motor efficiency.
? Recommended Grades for High-Speed Motor Applications
| Оценка | Толщина | Frequency Range | Приложение |
|---|---|---|---|
| 20XWH1200 | 0.15 мм | 400–800 Hz | EV motors, аэрокосмический |
| 20XW1300 | 0.10 мм | 500–1,000 Hz | High-speed motors, robotics |
| 15XW1150 | 0.08 мм | 600–1,200 Hz | Ultra-high-speed drives |
