2 CLUTCHES ND RKES General Information These are a few common applications. Clutches and rakes may be used wherever control of linear or rotary motion starts and stops are required. Electric clutches and brakes perform controlled start and stop functions between a constantly-running prime mover and a load. Electrical commands are generated manually (pushbutton) or automatically (switch, photocell, tape, sequence programmer, etc.) CLUTCH cceleration CLUTCH & RKE SICS EP0 NO SHOCK In this split-shaft application, the field and rotor are mounted to a motor and the armature to a reducer input shaft. low setting of the potentiometer on the control allows the clutch to engage the reducer worm gears smoothly, eliminating shock to the machine system. HIGH RESPONSE In this thru-shaft application, the potentiometer is set to full current. Engaging the clutch produces millisecond power transmission from motor to driven shaft. REVERSING In this application, the rotational direction of the driven shaft is determined by engaging different clutches. SPEED CHNGING The speed of the driven shaft is determined by engaging the appropriate clutch. DC clutches and brakes are magnetically-activated mechanical power transmission members normally installed between a motor shaft and driven shaft either a speed reducer or the final driven shafts. oth a clutch and brake transmit torque mechanically in response to an electrical signal. In a clutch, a disc on a revolving shaft is connected by magnetic attraction to a disc on a stationary shaft thus starting the drive. In a brake, one disc is fixed and magnetic attraction stops the revolving disc. THE DISCS RE CONNECTED Y MENS OF ELECTRO - MGNETIC TTRCTION COIL TERMINL COIL COIL FLUX MGNET RMTURE OUTER POLE FRICTION MTERIL INNER POLE RMTURE ROTOR RKE Deceleration In a brake, one disc (the magnet) contains a coil embedded in a circular horseshoe shaped cavity. The other disc (the armature) consists of segments of iron attached to backing plate. friction face is embedded in the magnet of the brake between the inner pole and the outer pole. When direct current is applied to the coil, magnetic force attracts the armature to the magnet. In the clutch, the magnet is stationary and the magnetic flux passes across an airgap and through a rotating rotor into the armature. NO SHOCK Potentiometer low: controlled stop. HIGH RESPONSE Potentiometer full: fast precise stop. EMERGENCY STOP Signal to brake brings malfunctioning system to a fast stop. HOLDING Fully engaged brake holds machine in stopped position.

CYCLING Programmed sequencer alternately engages the clutch and brake, producing programmed start-stop sequence. 56 Electrical Products Catalog

9 DC Shaft Mounted Selection CLUTCHES ND RKES Clutch and brake components for shaft-mounting provide flexible arrangements to satisfy almost any mechanical arrangement where power transmission capabilities are required. The most common arrangement is the bearing-mounted split-shaft application used to couple two in-line shafts. Clutches for through-mounting utilize bearing mounted sprockets or pulleys to drive parallel shafts. rakes are flanged mounted with the field held stationary on a machine member. Clutch brakes are bearing-mounted for split-shaft coupling. For application engineering see Pages -7. CLUTCH, ERING-MOUNTED, SPLIT SHFT (TYPE S) Clutches consist of a field, rotor, armature and its hub. The field is mounted on sealed ball bearings and remains stationary while the rotor revolves. The rotor extends through the field assembly and is attached to the drive shaft by a bushing, in many sizes. small tab holds the field stationary. The armature is mounted on a splined hub held on the shaft by standard tapered bushings. CLUTCH, ERING MOUNTED, THROUGH SHFT (TYPE T) The through-shaft mounting of the field and rotor is as described for the split-shaft version. The armature in this application is mounted to a bearing mounted sheave, sprocket or gear. special sheave adapter is necessary to assist in the mounting of the armature sheave. (Typical C50 and larger) FIELD T SHEVE DPTER RMTURE ERING-MOUNTED SHEVE RMTURE ROTOR RMTURE HU LL ERING USHING FIELD DRIVEN SHFT DRIVING SHFT DRIVEN SHFT DRIVING SHFT RKE, FLNGE MOUNTED The magnet is mounted to a machine member, or a stationary mounting plate by inner or outer mounted flanges. The space available determines which flange to use. Terminals are wired directly to the brake control terminals. The armature rides on a splined drive hub. Standard tapered bushings secure the hub to the rotating shaft, in most units. CLUTCH RKE When the clutch field is energized and the brake coil is deenergized, the clutch and brake armatures rotate with the drive shaft. When the clutch coil is de-energized and the brake coil energized, the two armatures are stopped. The rotor continues to turn. Operation is the same whether the clutch is bearing or flange mounted.

23 C RKES Double C-Face C rakes CM Series These double C-Face rakes are direct acting with only one moving part. They are spring set and electro-magnetically released. Movement is limited to a spring loaded pressure plate. Release is instantaneous. If power fails, the brake will immediately set and hold. FETURES utomatic Reset Compact Continuous Duty Dependable Full Torque Stop Horizontal/Vertical Mount Instant Magnetic Release One Moving Part Ready to Mount Shock Mounted Magnet Direct cting Flange/Foot Mounting Splined Hub Standard NEM Voltages/Frequencies Superior Disc Life Superior Thermal Capacity Double C-Face OPERTION Friction discs rotate with the motor shaft and are free to move axially on the hub. When the magnet coil is de-energized, a spring loaded pressure plate (magnet armature) presses against the rotating discs. Friction force stops and holds the motor shaft. The pressure plate retracts against torque springs by magnetic force when the magnet is energized. Friction discs are then released and free to rotate with the hub and motor shaft. manual release is also provided. SPLINED HU These C-Face brakes use splined hubs and internally splined friction discs as standard equipment. The spline design virtually elimi nates back lash which is a delayed action effect caused by excessive clearances between hub and discs. Splines in crease disc life because the many con tact points between hub and discs reduce the concen tra tion of stresses encountered with non-splined hubs having only a few contact points. rake coil leads connect directly to motor leads so that power is simultaneously supplied to both brake and motor. No control equipment is required. n instruction bulletin on mounting and hookup are included with each brake.

24 Double C-Face C rakes Washdown (ISSC) C RKES CMW Series Double C-Face brakes provide the simplest solution for adding a brake between a C-Face motor and a flanged gear reducer. These brakes offer the added feature of meeting ISSC standards, standards and other food industry washdown requirements. The CM-W double C-Face brakes are a perfect compliment to our C washdown motors. OPERTION The brake hub is attached to the motor shaft. The friction disk fits around the hub and is free to move axially along the hub. When the motor and the brake solenoid coil are de-energized, the brake is in a set condition. In a set condition, the pressure spring applies a force against the pressure plate to clamp the friction disc against the stationary disc and endplate to retard motion. The clamped friction disc prevents the hub and motor shaft from rotating. The brake is released electrically when voltage is applied to the solenoid coil of the brake. This produces an electromagnetic force which pulls the lever arm away from FETURES ISSC Certified CS Certified Meets National Dairy Standards Complies with Wisconsin Food and Dairy Regulations White FD pproved Epoxy Paint Stainless Steel Hardware Neoprene Gasketing Splined Hub for Increased Disc Life Sizes for NEM 56C to 8TC Frame Motors the pressure plate, releasing the clamping force on the friction disc. This allows the brake hub and motor shaft to turn freely. n important feature of this spring set brake is it s power failure characteristic. If a loss of electric power to the motor and brake occurs, the brake will automatically engage and hold the load provided that it has been properly applied and maintained. The brake coil is connected directly to the motor leads so that power is simultaneously supplied to the brake and the motor. No additional control equipment is required.
