MAXITORQ Jaw Brakes are designed to optimize size and space in your application. These electromagnetic brakes are ideally suited for positioning, holding and indexing, as well as situations that require the unit to maintaining positive registration between input and output shaft.With pins available for single-position engagement, electric jaw brakes are often used in applications that require exact positioning, including imaging, robotics, printing and labeling.As with all standard CJM products, our electromagnetic brakes can be modified for special uses. We can custom design a solution for your application.Our experienced engineers are ready for your toughest challenges and are only a phone call away at 860-643-1531.Features of Jaw Electromagnetic BrakesMAXITORQ Electric Jaw Brakes are available with either 24 or 100 volt DC coils as standard equipment, though other voltages are available to meet your needs. Carlyle Johnson stocks coils with voltages ranging 6 to 240 volts DC.CJM jaw electromagnetic brakes feature bi-directional operation, meaning operation is not dependent on rotation. Pins are also available with these designs to permit single position engagement.Overview - MAXITORQ Jaw Electromagnetic Brake UnitsADVANTAGESRadial flux path design eliminates bearing loadingHighest torque in smallest spacePositive tooth drive assures secure engagement with minimum backlashHardened jaws have teeth of high-carbon alloy steel for positive tooth driveOPERATIONTorque Range 5 lb. ft. to 1500 lb. ft.Bi-directional operationDrag-free neutral, no torque transmitted in the disengaged modeEngaged fully by induced magnetic fluxCUSTOMIZATIONFull range of tooth configurations for your indexing needsAvailable as single or multiple position registration for timed applicationsAvailable as spring setelectrically released for positioning and holding or electric actuationCustom designs and alterations availableADDITIONAL INFORMATIONJEB Brake Specification SheetUpload a CAD for a custom electromagnetic brake design.

Electric Motor Brakes Multiple Disc Spring Set Electric Brakes (EFS)EFS Electric Motor BrakeCarlyle Johnson's MAXITORQ Multiple Disc Spring Set Brakes and electric motor brakes are suited for applications demanding fast, positive braking to stop machines.These electric motor brakes are designed and built to provide unusually high torque for their compact size, and meet the braking requirements of a wide range of machinery.The design of CJM's EFS Electric Brakes (and electric motor brakes) incorporates a MAXITORQ multiple disc brake unit, which is kept compressed by radially-spaced coil springs between the armature and end plate, resulting in a constant "holding" force as long as the coil is not energized.When energized, electromagnetic force flows through the flux path to override spring pressure, releasing the friction discs for drag-free shaft rotation.Carlyle Johnson engineering staff can modify our standard electric brakes electric motor brakes, or we can develop a new product to meet your exact specific needs.Features of EFS Electric Brakes Electric Motor BrakesFurnished ready for use, Carlyle Johnson's EFS electric spring set electric brakes electric motor brakes can be quickly installed by sliding the brake over the keyed shaft and bolting it to a frame member. Optional C-faced non-magnetic flanges are available which enable direct-mounting on C-frame motors.EFS Fail-Safe brakes can also function as a torque-limiting device.Overview EFS Fail-Safe Electric Brakes & Electric Motor BrakesADVANTAGESAdvanced design provides unusually high torque for their compact sizeFast, reliable, positive braking actionFree-floating, drag-free neutralFurnished ready for quick, simple installation - no drive cups requiredCan be easily interfaced with NC and automated machinesEasily adjusted for wear minimal maintenance costsOPERATIONTorque range 3 lb. ft. - 1, 000 lb. ft.Actuation induced entirely by magnetic flux - 100VDC or 24VDC operationDirect mounting on C-framed motors with optional C-faced non-magnetic flangesOutput torque can be adjusted over the unit's operating rangeCUSTOMIZATIONOther actuation voltages availableSpecial coils availableAC to DC power supplies are availableCustom designs and alterations available

MAXITORQ Fail-Safe electric brakes electric motor brakes are a reliable, spring applied, positive acting brake that quickly starts a wide range of equipment.Designed and manufacturing with extreme precision, these electric brakes (and electric motor brakes) have been thoroughly tested to deliver proven, dependable performance in many diverse applications - from heavy-duty machine tools to fragile assembly and packaging equipment.Electrically operated, the brake's coil is sealed within a stationary housing which is supported on ball bearings.A powerful electromagnetic force disengages the disc pack unit to provide a low-drag neutral. Internal compressive forces are contained within the brake and are not transmitted through the bearings. The radial magnetic flux path provides maximum torque throughout the life of the unit.A significant portion of Carlyle Johnson Machine Co's production is devoted to the design and manufacture of special electric electric motor brakes and integrated systems designed to specific user requirements. If you need specialized engineering solutions we have the experience and skills to meet your transmission challenge.Features of FEA Spring Set Electric Brakes Electric Motor BrakesCarlyle Johnson's MAXITORQ multiple disc spring set electric brakes are proven to provide long service life, and can be rebuilt without requiring any special tools. There are no slip rings, no brushes and no troublesome wiring issues that make repair difficult.CJM's multiple disc spring set brakes also feature an adjustable end plate design. With few moving parts and a stationary housing, these remote-controlled brakes are effective in helping to protect personnel from accidents and machines from damage.Overview - FEA Spring SetFail-Safe Electric BrakesADVANTAGESHighly repetitive, spring-set brakeUnique end-plate design allows easy wear adjustmentStationary field eliminates need for brushes and ringsStationary cylinder assemblyHighest torque in the smallest space within the industryCompletely assembled, ready to installNo levers, cams or highly stressed partsOPERATIONTorque range 12 lb. ft. - 600 lb. ft.Positive engagement disengagement possible at any speedExclusive MAXITORQ long-life floating discs pack for low hear, low neutral drag and consistent releaseRuns in both rotation directions, wet or drySpring applied, electrically releasedCUSTOMIZATIONAdjustable end-plate designCustom disc pack design, special coilsModified magnetic circuitsVariety of electronic controls available to provide slower or faster actuation and release as well as controlled acceleration and decelerationCustom designs and alterations available

MAXITORQ Zero Backlash electromagnetic brakes are designed to optimize size and space in your application. They are ideally suited for positioning, holding and indexing as well as for situations that require the unit to maintain positive registration between an input and output shaft.CJM jaw brakes are bi-directional, and operation is not dependent on rotation. Pins are available with these designs to permit single position engagement, making it ideal for printing, labeling and other special applications which require exact positioning.Our trained engineers can modify our electric electromagnetic brakes for your needs.We can also custom design a new product to meet your requirements.
