Abstract

24,977. Barbour, R. H. Nov. 9. Electro-magnets.-To prevent chattering, the armature 4 of a singlephase electro-magnet is provided with shortcircuited coils 1 which are let into the armature face in positions opposite to the polefaces of the magnet carrying the winding 5. When the two polefaces of the magnet are in the same plane, the coils 1 may be arranged in diametrically-opposite positions; or the armature face may have two coils let into it opposite each pole-face; or a single coil may be let into the armature face opposite the centre of a pole-face. The invention may be applied to ' no-volt ' release magnets for motor-starters,
