Prepared by:
Fan / Blower Data:
Fan power (hp):
Fan speed (rpm):
Enter the shaft speed that the brake disc will be mounted to. For direct drives, this is the motor nameplate speed.
Impelller OD (in):
This and the next two values are used to estimate the inertia. If the inertia is known, skip to that data field.
Impeller ID (in):
Impeller weight (lbs):
Impeller inertia (lbs-ft
2
):
Number of discs:
Stopping time (secs):
Enter the desired time in this field. The calculator may have to change this value to fit our brake offering.
Brake & Disc Selection:
Search Filter
No filter:
Minimize equipment cost:
'Minimize equipment cost' will limit offering to braking systems which will perform the task without any regard to pad or disc life.
Balance cost & performance:
'Balance cost & performance' will select the middle one third from all permissible combinations
Maximize performance:
'Maximize performance' will present brake systems that will maximize pad life and minimize disc temperature but may be too large for the application.
Disc options:
Select a disc
None
Brake options:
Select a brake
Grade 'G' will produce the highest torque whereas grades 'E' and 'C' may be required in high speed applications.
