Design Features
Versatility and Flexibility
Wide range of sizes
Coil
Available in various voltages for each model.Warner Electric controls (see controls section) provide optimum performance and controllability. All Warner Electric units are either UL listed or recognized. All are CSA certified.
Armature
Fluted and segmented.
Designed as a cooling
device to dissipate maximum heat and
increase life.
Magnet or Field
Brake magnet mounts to anymachine member. WarnerElectric clutches are availablein flange mount or bearingmount designs.
Bushings
Standard industry bushingsare used in all the larger
sizes to meet your shaft
size requirement. Several
bore sizes are available as
standard in each of the
smaller models.
Armature Drives
Heavy duty spline driveabsorbs shock. Rugged, longlife materials used in outer andinner spline members. Pin drivedesignavailable for normal,lighter duty applications. Anti-backlash armatures availablefor sizes 170, 250, and 400.
Friction Material
Standard friction material represents theoptimum in high torque performance andlong life. Long wearing LK facing isavailable in the larger models to meetapplication requirements whereexceedinglylong life is a criticaldesignfactor. Custom design brakes and clutches are
user assembled from standard compo-nents for optimum performance in thesmallest possible package size.
LK friction material
Warner Electric offers a special lowcoefficient (LK) friction material for many
standard clutches and brakes. Since
two friction materials are available, a
comparison of LK to standard is in
order.Since LK has a lower coefficient offriction, lower torque capability results.
With LK facing, static torque capacity is
only about 60% of catalog rating for any
given size. So if a specific size clutch or
brake is chosen for its rated torque
capacity and LK facings are substituted
for standard, a larger size unit will beneeded to provide the same torque.If lower torque ratings can be consid-ered a disadvantage, what are the ad-
vantages of LK material? The first is
longer life. An ideal situation for LK use
is a constant slip application which
requires a large unit for high heat dissi-pation. Another feature of LK is "softer"
pickup. Since more slippage will occur,
engagement time is increased andshock is reduced. LK material will also
reduce engagement noise, so it can
be successfully employed where high
noise levels are a problem. It is the
standard facing in all tension brakes
and motor brake
industrial magnets. For more information on LK facing,see page 232. Easily adaptable to any mountingrequirement Low initial cost Wide range of models and options 10 sizes from 1-1/4" to 15-1/4"diameter 45 models of clutches, brakes andmotor brakes Torque range: 5 lb.in. to 1350 lb. ft. Horsepower capability to 100 HP Assembled around the basic compo-nents of an electric
