1 -ACTUATED -ACTUATED Clutch/brake / odels (5 ~ 32) odels (2.4 ~ 1) 111 odels (5 ~ 32) odels (2.4 ~ 1) Application rinting machinery, bookbinding machinery, food machinery, wrapping machinery, textiles machinery Clutches and Brakes that Accurately Control a Variety of General Industrial achinery 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. art of their appeal is the simplicity of control and ease of maintenance.

3 -ACTUATED roduct Lineup 11 Electromagnetic-actuated Clutches - Flange-mounted Type RoHS-compliant Flange-mounted type Stator and rotor are combined and directly mounted on stationary parts, such as frames, and fixed in place. These are short in the axial direction and can make effective use of space near windows. Select the armature according to the coupling type used (through-shaft, butt shaft, etc.). Clutch 5 32 Operating temperature [ ] Backlash Electromagnetic-actuated Clutches - -mounted Type Zero These integrate the stator and rotor, which are held to the stationary parts of the machine by a drive pin arm; the rotor is locked to the rotation shaft by a key. They are designed to be relatively easy to mount, reducing the processing work required for mounting. Clutch 5 32 Operating temperature [ ] Backlash Zero RoHS-compliant -mounted type 111 Electromagnetic-actuated Brakes Brakes are used to brake and hold rotating bodies. The flange of the stator is locked securely to a strong stationary part. Select an armature that factors in the mounting space available. Brake 5 32 Operating temperature [ ] Backlash Zero RoHS-compliant / Electromagnetic-actuated Clutches & Brakes - One-touch-mounted Type These models adjust the gap to the al surface that clutches and brakes require to operate and come pre-assembled. Clutches are simply placed on the shaft and brakes mounted on the flange surface. They do not require gap adjustment or adjustment of concentricity/ parallel misalignment, greatly reducing installation work.

5 -ACTUATED ounting Example Flange-mounting example with 11 The stator is directly mounted on a stationary part, such as a frame, by a mounting flange, and fixed in place. The rotor is locked to the rotation 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 etal disc spring Key Butt shaft mounting example with In designs that use butt shafts, the two shafts can be reliably centered using fitting flanges, as shown in the figure. Air gap a type-i Fitting flange Drive pin Set screw Air gap "a" Air gap -mounting example with The stator is integrated with the rotor via a bearing and held to the stationary parts of the machine by a drive pin arm. The rotor is locked to the rotation shaft using a set screw. The stator and rotor form a magnetic pole via the bearing. ounting example with Simply insert the shaft in the sleeve and fasten a on the shaft end and mounting is complete. Drive pin arm Key Stator Rotor etal disc spring Key Drive pin ulley mounting bolt Set screw Gudgeon bolt Air gap Air gap "a" Example of combining clutches In this example, two clutches are assembled on a through-shaft. This is very effective when controls such as two-step speed changing and forward/reverse operation are needed and space is limited.

6 ounting Example COULINGS type-3 mounting example with 111 When armature type-3 is directly mounted on the end face of a V pulley, no armature hub is needed, making for a very efficient design. These are optimal when space is limited or when a shaft overhangs from a wall and the overhang load must be kept extremely low. Air gap "a" type-2 mounting example on vertical shaft with 111 type-2 is a special armature that puts the boss part of the armature hub into the space within the stator. That makes it compact. It is short in the axial direction even when a pulley or the like is installed on the tip of the brake. Since running is zero, it does not take up space even when mounted on a vertical shaft, and is also easy to install. Air gap "a" can be set easily using collars and shims. Corrections are easily accomplished by adding or removing shims. ET BUSHINGS SEED CHANGERS & REDUCERS INVERTERS LINEAR SHAFT DRIVES V pulley Air gap "a" TORQUE LIITERS ROSTA SERIES Collar and shim type-3 mounting example with 111 If a rotating body floating above a shaft by means of a bearing (an idler pulley, guide roller, or the like) has an armature type-3 mounted on it directly, it can be assembled easily without taking up a lot of space. Air gap "a" can be set easily using collars and shims. Corrections are easily accomplished by adding or removing shims. Air gap "a" ounting example with Collar and shim Simply insert onto the shaft to be braked and lock the on the wall surface and mounting is complete. Be careful when designing that the mounting shaft does not cantilever and end up a three-point mounting.
