Wave-shape showing for multi-pole ferrite ring- saddle shaped and sinusoidal

Radial multi-pole ferrite ring, with high surface magnetic flux density, absolutely its performance is better than traditional tile-shaped ferrite magnet, magnetic path design is completely different with radiation ring. Lots of customers use tile-shape ferrite magnet to make the samples, then create tooling again for multi-pole ferrite ring.

Usually, the surface of the radiation ring is saddle-shaped, the radial multi-pole ferrite of ring magnetic field distribution on the surface is sinusoidal, so it is more better for motor design.

What is saddle-shaped? And what is sinusoidal? Here give you the pictures as below.
