In accompanying drawing 7, X is the magnet-wheel anglec of rotation, and unit is °; Y is adsorption affinity, and unit is N.Can show that from the analogue computing of finite element number of pole-pairs is more by accompanying drawing 7 is known, adsorption affinity more tends to be steady, number of pole-pairs less magnet-wheel adsorption affinity large small leak fluctuation larger.Adopt 8 number of pole-pairs magnet-wheel adsorption affinity undulated control within 5%, and magnetic adsorbability is also higher.
For the magnet ring of 8 number of pole-pairs compositions, the volume proportion of adjacent longitudinal permanent magnet unit and horizontal permanent magnet unit also has different impacts to adsorption affinity.For the size inlet coefficient hoop angle of both reactions is intuitively than k,
k=n/(n+m)
In above formula: nfor radial permanent magnet unit angle; mfor hoop permanent magnet unit angle.
In accompanying drawing 8, X1 is k value; Y is adsorption affinity, and unit is N.Known in the emulation of finite element by accompanying drawing 8, visible adsorption affinity is at about k=0.6, and magnet-wheel adsorption affinity will reach peak value.And k is in the interval of 0.4-0.8, adsorption affinity is also gratifying.
The utility model optimizes permanent magnetic suck block construction in permanent magnetic suck wheel, to magnetize angle by optimizing the arrangement of permanent magnetic suck unit, and the outer ring adsorption affinity of magnet ring is strengthened, and inner ring adsorption affinity is almost nil.Improve the unit magnetic usefulness of permanent magnet unit, reach the adsorption affinity of when same volume is not optimized nearly 2 times.
