FLUX-FOCUSED SHAPED PERMANENT MAGNET, MAGNETIC UNIT HAVING THE MAGNETS, DEVICE HAVING THE MAGNETIC UNITS AND METHOD FOR ASYMMETRICALLY FOCUSING FLUX FIELDS OF PERMANENT MAGNETS

摘要

A flux-focused, shaped permanent magnet includes a body of magnetic material having multiple surface contouring to form a reduced flux side with convex surfaces and an increased flux side with concave surfaces. The surfaces develop high and low resistance external flux paths creating focused asymmetric flux fields. A magnetic unit having the shaped permanent magnet and a magnetic flux attracter or two shaped permanent magnets interconnected by two segmented permanent magnets and a kinetic device having a stationary stator ring, a rotor disc rotating within the stator ring and a multiplicity of the magnetic units on the stator ring and the rotor disc, are also provided.
