The best basis to ensure quality and efficiency of lamination stacks
compacore® lamination stacks are manufactured from isovac® electrical steel grades made by voestalpine (www.voestalpine.com/isovac). The high-quality materials, providing great strength and punchability, are the perfect base for high performance.
In addition, the high resistance of the electric steel helps to increase the efficiency of the electric motor. It allowes to place the magnets as close as possible to the rotor, inside the rotating motor part. The material strength determines the thickness of the arm that retains the permanent magnets to the rotor and defines theier distance to the stator. Providing high strength and a minimum distance, voestalpine electric steel improves the performance of electric motors.
