Spring Applied Brakes

Inertia Dynamics' Spring Applied Power-Off brakes are designed to decelerate or park inertia loads when the voltage is turned off either intentionally or accidentally, as in the case of a power failure.

Flange Mounted Spring Applied Brakes — Type FSB

Inertia Dynamics type FSB brakes are designed to decelerate or hold inertial loads when the voltage is turned off. These brakes can be mounted to a bulkhead or motor.

MPC — Brake Only Module (Power-Off) with Output Shaft C-Face

The MPC is a power-off brake module with an output shaft. The unit mounts on a C-Face motor and the output can be coupled to a C-Face gear reducer. Ideal for creating brake motor packages on smaller servo and stepper frame motors.

Reverse Mounted Spring Applied Brakes — Type FSBR

Inertia Dynamics type FSBR brakes are designed for applications requiring minimum space (short axial length) or on motors with short shaft extensions. When mounted, the armature hub is installed on the shaft first, then the brake is installed over the hub and attached to the motor.

Manual Release, Spring Applied Brakes — 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.

Spring Applied Brakes — Type SAB

Inertia Dynamics features a type SAB spring applied brake. SAB brakes are designed to be engaged and disengaged in a static condition at zero RPM. They are best used as a parking brake to hold a load in position. These brakes can be mounted to a flange or motor using thru-holes or tapped holes in the field cup. A conduit box is optional. SAB brakes have been used extensively for servo brake applications. High temperature coil insulations are available upon request.
