Table 8-25: FB-5E, FB-8E, FB-10E, and FB-15E Standard Specications
Notes:
Above table applies to standard brake specication under standard brake torque. Special brakes may perform dierently from those shown. Initial brake
torque may be lower than specied brake torque. If this is the case, under light load start and stop the motor to wear-in the braking surface. To improve
performance for positioning accuracy or lifting applications, consider using fast braking action circuit. If the brake is operated at a rate greater than the
Allowable Brake Work Capacity, E0, the brake performance may degrade or become inoperable.
[1] Also applies to wiring where brake is powered separately from the motor leads.
Brake Models FB-5E, FB-8E, FB-10E, and FB-15E
Table 8-25 lists the standard specications for Models FB-5E, FB-8E, FB-10E, and FB-15E.
1. Standard Brakemotor Specications
Figures 8-11 and 8-12 illustrate the construction of the brake. Among the brake parts, the stationary core (1),
solenoid coil (20), and stud bolt (19) constitute an integral subassembly unit. The stud bolt (19) keeps the armature
plate (4) from rotating, but the plate moves axially by electromagnetic attraction and the tension of the pressure
spring (2). The adjusting washer (18) and spring washer (17) hold the brake shoe (8) against the nut (16) at all times.
The brake lining (9) is t to the hub (11), which is secured to the motor shaft with a key.
