The selection process hinges on the application withmany variables to take into consideration. Often times there are several brake or clutch options that might do the job—the key is findingthe best solution for your application.This catalog contains several aides to assist in the selection process. CLUTCH AND BRAKE TECHNOLOGIES—This catalog contains clutch and brake information for Wrap Spring and ElectromagneticFriction Clutches and Brakes. Pages 6-13 offer operation, design and application examples of both technologies. The printed tabsoffer a quick way to find the technology and products you need. Engineering guidelines appear at the end of each section.THE GENUINE WRAP SPRING product section begins on page 15.THE FRICTION product section begins on page 87. SELECTION BY MOTION TYPE—The chart on pages 4 & 5 categorizes our clutches and brakes by type of motion. The basic motionsare START, INDEX, SLIP, STOP and HOLD. Each of these motion types are noted by an icon on the left side of this chart. As youbrowse through this catalog, you will see these same motion icons in the top header of the product pages. If you know that yourapplication requires a specific motion, this chart may be a helpful place to start your brake and clutch selection. SELECTION BY CAPABILITY—The chart on page 5 will help you to determine which technology may work best in your application:Wrap Spring or Friction. Your application may have specific requirements of a brake or clutch such as torque, speed, accuracy, etc.This chart may help you determine whether The Genuine Wrap Spring products or one of our Friction Clutches or Brakes will be bestsuited for your operation.www.thomsonlinear.com1

Clutches & BrakesCLUTCH/BRAKEPACKAGESClutches & BrakesProduct OverviewWrap Spring ProductsENGINEERINGGUIDELINESTHE GENUINE WRAP SPRING ENGINEERED PRODUCTSEngineered products are specially designed to solve specific and unique applicationrequirements. The products shown are the result of years of experience in providing innovative solutions for applications, including paper feed drives, agriculture equipment, copiers, robotics, etc. These solutions are now available as “engineered” products, whichinclude the DL, MAC, SP and BDNB.CLUTCH &CLUTCHCOUPLINGSFriction PERMANENT MAGNET POWER-OFF BRAKESPermanent magnet power-off brakes (RAB) provide zero backlash stopping and/or holding ofa load in the absence of power. While the field (electromagnet) is fixed and prevented fromrotating, the output hub assembly is secured to the shaft. In the absence of power, the fixedand rotating components are engaged, thus stopping and/or holding the load. When the coilis energized, rotating components are disengaged, thus allowing the shaft to freely rotate.ENGINEEREDPRODUCTSFRICTIONFRICTION BRAKESElectromagnetic power-on (BF) brakes provide an efficient, switchable means of stoppingand/or holding a load. Spring-set electromagnetic power-off (SB, FSB, PMB & MBRP)brakes provide a safe, efficient means of stopping and/or holding a load in the absence ofpower.BRAKESFRICTION CLUTCHES & CLUTCH COUPLINGSElectromagnetic clutches and clutch couplings are available in six frame sizes and offeredas shaft-mounted or flange -ounted models. The CS and CSC Series provide an efficient,electrically switchable link between a motor and a load. These models offer full corrosionresistant, rotating components designed for low inertia and minimal drag, zero backlashand integral long-life bearings.FRICTION ENGINEERED PRODUCTSEngineered products are specially designed to solve specific and unique applicationrequirements. The products shown are the result of innovative solutions we provided forapplications such as document handling, copiers, ATM machines, dispensing machines,robotics and military aerospace actuators.

The Genuine Wrap Spring Clutches & BrakesOperation Design PrinciplesThe basic wrap spring clutch consists ofthree elements: an input hub, an outputhub and a spring whose inside diameteris slightly smaller than the outside diameter of the two hubs.When the spring is forced over the twohubs, rotation in the direction of thearrow wraps it down tightly on the hubs,positively engaging them. The greaterthe force of rotation, the more tightly thespring grips the hubs.Output HubWrap SpringInput HubWrap Spring Design ConfigurationsControl TangControl TangOutputInputOutputInputOutputInputModel OOverrunning ClutchIn its basic form, the wrap spring clutchoperates as an overrunning clutch. Whenthe input hub is rotated as shown, thespring wraps down to engage the twohubs. If the input is stopped or reversed,the spring unwraps to release the outputhub, allowing the load to overrun. PSISeries overrunning clutches can also perform one-way indexing and backstoppingfunctions.Start-Stop Clutch(Random Positioning)Single Revolution ClutchModifying the basic PSI Series clutchwith a control tang allows the clutchto engage and then disengage the loadwhen the control tang is locked in position by the stop collar. Once disengaged,the load coasts freely from the continuously running input.Combination Clutch/BrakeThe wrap spring clutch/brake utilizes twocontrol tangs to hold either the clutch orbrake spring open. When the clutch andbrake control tangs rotate with the inputhub, the input hub and output shaft arepositively engaged by the clutch spring.When the brake control tang is locked bythe stop collar, the brake spring wrapsdown to engage the output shaft to thestationary brake hub. At the same time, theclutch spring unwraps slightly, allowing theinput hub to rotate freely.6Model SModel SSA second tang, secured to the outputhub, allows PSI Series clutches to perform single revolution functions. Whenthe control tang is engaged, the outputhub cannot overrun because it is securedto the spring. Single revolution PSI, SPand SAC Series clutches are capable ofstopping only 10% of their starting loadcapacity. A CB Series unit is recommended where higher braking torque isrequired.Brake Control TangClutchControl TangStationary BrakeHubOutput ShaftInput Hubwww.thomsonlinear.com
Clutches & BrakesThe Genuine Wrap Spring Clutches & BrakesApplications When the spring is allowed to wrapdown (or grip the hubs), the output hubwill accelerate to the input RPM in .003seconds, the output in .0015 seconds.The dynamic torque of accel erationor deceleration is proportional to theRPM multiplied by the load inertia anddivided by the acceleration time. Thisfact indicates that spring clutches andbrakes are inertia sensitive—the moreinertia, the higher the dynamic torque.The torque demand of the spring clutchis equal to the system frictional torqueof the load plus the dynamic torque ofacceleration. When coming to the stop position ofthe cycle, there must be enough energy in the rotating mass of the load toallow the spring to release its grip o

clutches and brakes. The "Electromagnetic clutches and brakes" is a generic term used to refer to the functions such as transmission and interruption or deceleration and stoppage of torque by electro-magnetic action. They are classified mainly by three in accordance with the intended use. Electromagnetic micro clutches and brakes
How do centrifugal clutches or brakes work? Centrifugal clutches and brakes use centri-fugal forces to transmit power (clutch) or to limit speed (brake). As the brakes are based on a physical principle, centrifugal clutches or brakes do not require any additional external power supply, which makes them a perfect solution for safety applications .
Clutches, Brakes, Coupling, and Flywheels Clutches, brakes, couplings, and flywheels are a group of elements usually associated with rotation that have in common the function of storing and/or transferring rotating energy In analyzing the performance of these devices we shall be interested in: The actuating force The torque transmitted The .
