Magnetic damping system having low induction magnet |
摘要 |
A magnetic damping system for induction devices having electroconductive disk armatures includes a low induction, high coercive force magnet that is vertically elongated and has a horizontal direction of magnetization parallel to the disk. Flux concentrating pole pieces adjoin the magnet pole faces for vertically directing two closely spaced braking magnetic fields from a pair of pole tips and into the disk. A temperature compensating arrangement covers the sides of the permanent magnet between the edges of the pole pieces to efficiently compensate for higher reversible temperature coefficients of magnet remanence.
