Abstract:
A brake is provided that employs an electromagnetic or magnetic circuit to disengage the brake and in which a reed switch is used to indicate an operating condition of the brake. The reed switch is positioned across an air gap between two members of the electromagnetic or magnetic circuit. The state of the reed switch changes in response to flux leakage at the air gap and may be used to monitor for potential failures in the operation of the brake including a failure to operate due a lack of current or the failure of the brake to disengage due to an obstruction.

Claim (Index 13):
A brake, comprising:\n a friction plate configured for coupling to a shaft for rotation with the shaft about an axis of rotation; a pressure plate disposed about the axis on a first side of the friction plate and fixed against rotation; an armature plate disposed about the axis on a second side of the friction plate; a field shell disposed about the axis on an opposite side of the armature plate relative to the friction plate, the field shell including first and second components; a spring biasing the armature plate in a first axial direction towards the friction plate and away from the field shell to engage the brake; a permanent magnet disposed between the first and second components of the field shell and forming a magnetic circuit with the first and second components of the field shell and the armature plate, the magnetic circuit urging the armature plate in a second axial direction away from the friction plate and towards the field shell to disengage the brake; and, a first reed switch extending across an air gap between first and second members of the magnetic circuit, a state of the first reed switch indicative of an operating condition of the brake.
