ABSTRACT:
In an electromagnetic brake, disc shaped ferromagnetic armatures provide the braking effort and are included in stacks of brake discs flanking an annular electromagnet assembly formed by separate inner and outer annuli of ferromagnetic annuli, and an annular rigid coil unit concentrically between the annuli. The outer annulus is gapped so that a radial extension of the coil unit can pass through it, and fingers on one of the armature discs or upon a unit to which the brake is applied restrain the armatures, the coil unit, and any other stationary brake discs in the assembly against rotation. The armature discs may form either the innermost or the outermost discs in their respective stacks according to whether the brake is to be on or off when deenergized.
