Manual Release, Spring Applied Brake – Type FSBR

Inertia Dynamics features a type FSBR015 spring applied brake with a manual release lever. The brake incorporates a lever which is rotated to mechanically engage the clapper plate. The clapper plate acts against the compression springs and allows the armature disc to spin freely. The brake is now free of torque. An optional microswitch is activated on the field assembly to disconnect power to your system in case of an accidental start-up with the brake manually released. To return the brake to normal operation, rotate the lever to re-engage the brake and produce torque.

Typical applications include wheelchairs, three-wheel carts/scooters, and fractional horsepower motors. The brake is available with a higher static torque rating for non-dynamic braking applications where only a statically engaged parking brake is needed.

For variations on the manual release brake configuration, in support of high-volume OEM applications, consult Inertia Dynamics.

CAUTION: Inertia Dynamics recommends the use of a switch or other method to ensure customer application using this brake is not operated while brake is in the manually released mode.
