Hysteresis Device
Special Designs & Modifications |
|
|
Since
1953, Magtrol has created literally thousands of special and
modified brake and clutch designs to help solve specific application
problems for our customers.
Common Specials and Modifications Include:
Blower-cooled
Brakes
| Unlike many other forms of braking devices,
Magtrol Hysteresis Brakes can be safely operated at relatively
high speeds, provided the combination of applied torque and
speed of operation do not cause the brake to be operated above
its kinetic power rating. The kinetic power rating of the brake
can be increased significantly, when necessary, by forced air
cooling. Magtrol has designed brakes with provisions for forced
air cooling utilizing compressed air supplied by the machine
builder and has also created special designs and blower packages
for use in high-torque/high-speed applications where compressed
air is not available. |
Mounting Options
Although intended for coupled service, moderate overhung loads
can be tolerated, depending on such operating characteristics
as speed, weight, and center of gravity of load. Care should
be taken to make certain that the shaft is properly aligned.
Couplings should be of proper size and flexibility to adequately
protect bearings from undue stress and shock loading.
Base Mount
Base mounting is standard on all HB-840 and HB-3500/HB-3500M
double brakes. Base mounting is also available as an option
on 450 and 1750 oz·in single brakes.

Ordering Information:
An HB-450 with a base mount is an HB-451 and an HB-1750 with
a base mount is an HB-1751.
Extended Shafts
Higher
Torque Capability
It is Magtrol's policy never to overstate the capabilities
of our products. As a result, our brakes are conservatively
rated. Higher torque values (15-25% above rated torque)
are typically available from each brake, depending on
the brake being ordered. In addition, special designs
capable of producing even higher torques are available.
Contact Magtrol for more information. |
