ELECTROMAGNETIC-ACTUATED CLUTCHES AND BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES ELECTROMAGNETIC CLUTCH AND BRAKE UNITS Application Printing machinery, bookbinding machinery, woodworking machinery, semiconductor manufacturing equipment Connection and Release, Required Functions Integrated in a Compact Form Factor, Electromagnetic Clutch and Brake Units Multiple clutches and brakes are required when designing complex actions. You can select from our clutch and brake units to get the operation you require rather than just combine as many clutches and brakes you need. We provide not just clutch and brake combinations, but total solutions that also include motors, speed reducers and the like. Some exceptions apply

ELECTROMAGNETIC-ACTUATED CLUTCHES AND BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES Product Lineup ■ Butt shaft construction, drip-proof type This design preserves the performance of Handling is made simpler by drip-proof construction clutch and brake to the maximum extent. that encloses clutch and brake inside a light alloy housing. ■ Mounting direction freedom Disc springs are used, so this clutch/brake unit can be used vertically. Its construction is sturdy, yet lightmass. Its easy-to-use butt-connected construction is drip proof, making it suitable for a variety of general industrial machinery...

289 COUPLINGS ETP BUSHINGS ELECTROMAGNETIC Output shaft Bearing cover Bearing cover Brake stator Input shaft CLUTCHES & BRAKES ■ Power transmission Input and output shafts are isolated. A pulley or the like is mounted on the input shaft, connecting it to the driver so it is always rotating. When electricity flows to the clutch, the two shafts are connected, and rotation is transmitted. If the brake mounted on the output shaft is supplied with electricity simultaneous with clutch current being shut off, the input and output shafts are isolated and the output shaft is quickly braked. The end faces...

ELECTROMAGNETIC-ACTUATED CLUTCHES AND BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES Product Lineup ■ Compact, space saving These are practical units in which worm These are very compact units that combine a worm reducers are directly connected to clutch/brake reducer and clutch/brake in a single unit. They can greatly save on space required for mounting. ■ Easy to mount and handle V pulley comes mounted as standard on the input A part, so simply connect it to a drive with a belt. Install the speed reducer to complete the mounting. No units in advance. A standard V belt pulley is installed on the input...

■ Power transmission V pulley is installed on the input part of the clutch, connected by a belt to the drive, A Worm gear speed reducer Clutch stator and rotates continuously. When current flows to the clutch, rotation is transmitted to the worm shaft, and the output shaft of the speed reducer rotates. If the brake is supplied with electricity when clutch current is shut off, the output shaft stops.
