Vortex Engineering are manufacturers of clutches and brakes which are intended for start-stop applications. They come in various types to meet different requirements. Type EAA is an electromagnetic single face brake, "normally off"type. It has two basic parts. The stator which consists of a coil and friction material, and the armature plate. The braking torque is produced by means of the electromagnetic force which is developed when the current flows through the brake coil, thus attracting the armature plate to the stator with friction material, thereby arresting the motion, and is released immediately due to a sinusoidal wave spring, when current through the coil is cut off. These brakes are used for dry applications only. Features: designed for simple mounting and easily adaptable to any mounting requirement; sinusoidal wave spring enables backlash-free transmission, enabling very short response time on disengagement; the friction faces are completely separated by the spring eliminating any drag and permitting use at very high idling speeds; and, units are practically maintenance-free due to the stationary coil and highly we arresistant asbestos-free friction surfaces. Standard operator, voltages: 24 V DC, 96 V DC and 190 V DC. Other voltages at extra cost. Available in various bore sizes.
