ELECTROMAGNETIC-ACTUATED CLUTCHES & BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES ELECTROMAGNETIC-ACTUATED CLUTCHES & BRAKES 1 Printing machinery, bookbinding machinery, food machinery, wrapping machinery, textiles machinery Clutches and Brakes that Accurately Control a Variety of General Industrial Machinery Clutches accurately connect and release power by being located between the driver and the load. Brakes are used to slow or stop load inertia and machinery and to hold things in stationary positions. Using these basic operations and combining clutches and brakes enable a variety of applications such as stepped speed-changing mechanisms, switching between forward and reverse operation, positioning/indexing, and inching. Part of their appeal is the simplicity of control an

ELECTROMAGNETIC-ACTUATED CLUTCHES & BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES Mounting Example Flange-mounting example with 101 Butt shaft mounting example with CS The stator is directly mounted on a stationary part, such as a frame, by a In designs that use butt shafts, the two shafts can be reliably centered mounting flange, and fixed in place. The rotor is linked to the rotation using fitting flanges, as shown in the figure. shaft using a key. The stator and rotor are combined via a narrow air gap that serves as part of the magnetic circuit to form a magnetic pole. Stator Rotor Air gap a Armature...
