Abstract
Cores for electromagnetic devices are discussed. In one example, a core comprises three arc-shaped limbs. Each limb has a first end and a second end, and is arranged around a central axis. The first ends of the limbs are mutually connected at a first position along the central axis, and the second end of the limbs are mutually connected at a second position along the central axis. Each limb comprises a plurality of bent electrical steel strips. Methods for manufacturing such cores are also discussed.
Claims21
A core suitable for an electromagnetic device, the core comprising three arc-shaped limbs wherein each limb is arranged around a central axis, and each limb has a first end and a second end, wherein the first ends of the limbs are mutually connected at a first position along the central axis, and the second end of the limbs are mutually connected at a second position along the central axis, and wherein each limb comprises a plurality of bent electrical steel strips.
A method of manufacturing a core suitable for an electromagnetic device, the method comprising:
- forming three sets of strips from one or more sheets of electrical steel, wherein each set of strips comprises a plurality of strips, and the one or more sheets of electrical steel comprise an insulating surface layer;
- arranging each of the three sets of strips into a respective stack;
- bending each stack into an arc-shaped limb, each limb having a first end and a second end;
- positioning each limb around a central axis;
- mutually connecting the first ends of the limbs at a first position along the central axis;
- and
- mutually connecting the second ends of the limbs at a second position along the central axis.
