Laminated core

Laminated core

The ribbon is punched into a ring shape or directly laminated and bonded together in a special way, and after heat treatment, it obtains good soft magnetic properties.


Performance characteristics:
(1) Excellent characteristic frequency
(2) Low loss, reducing temperature rise
(3) Good temperature stability, able to work for a long time from -55 ℃ to 130 ℃
(4) High magnetic permeability, low coercivity


Application areas:
Drone motor;
Dental drill;
High speed motor;
Handheld electric drill.




Production Steps
