Stator Laminations
Silicon Steel Stator Laminations
Cost-effective, high-efficiency magnetic cores for industrial and commercial electric machines.
The Industry Standard. Engineered to Outperform.
Silicon Steel laminations are the backbone of modern electric motors, trusted across industries for their balanced magnetic performance, proven reliability, and manufacturing scalability.
The Right Material for High-Volume, High-Reliability Applications
Silicon Steel (Fe-Si) laminations are precision-stamped, electrically insulated magnetic steel sheets stacked to form stator cores. The addition of silicon increases electrical resistivity, directly reducing eddy current losses and improving efficiency across a wide operating frequency range. The result: a dependable, well-understood material optimised for motors where efficiency, cost, and scalability all matter.
