Abstract
The utility model relates to a hybrid permanent magnet device with a rotating magnetic core and a forward polarized magnetic steel combination which mainly comprises a rotating magnetic source, a forward polarized magnetic steel combination and an outer polar plates. The pole faces of magnetic steels are contacted with the planes of intermediate magnet-conducting plates; the magnetic steels are vertically placed; the polar directions of all the magnetic steels are the same; and the forward polarized alnico combination is clamped between the two outer polar plates, which are fixed on the left and the right semi-circular-hole magnet-conducting blocks of the rotating magnetic source through bolts. The forward polarized magnetic steel combination forms a multi-pole, multi-loop dense magnetic circuit structure, the magnetic action is uniform, the penetration height of the magnetic lines of force in a workpiece can be notably reduced, and therefore the hybrid permanent magnet device is favorable for the holding of a thin workpiece.
