All Inertia Dynamics standard brakes and spring applied brakes are recognized by Underwriters Laboratories to both U.S. and Canadian safety requirements. Inertia Dynamics' Power-Off Brakes are designed to decelerate or park inertial loads when the voltage is turned off either intentionally or accidentally, as in the case of a power failure. 

Inertia Dynamics Brakes We Offer:

Flange Mounted Spring Applied Brakes

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.

Brake Only Module (Power-Off) with Output Shaft

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

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

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

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

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.

Flange Mounted Brakes

Flange Mounted Brakes — Type FB

FB series power-on brakes are used to stop or hold a load that is coupled to the armature hub assembly.  The armature hub is attached to the load shaft.  The field assembly is mounted to a bulkhead that is perpendicular to the shaft.

Shaft Mounted Clutches/Power-On Brakes

Shaft Mounted Clutches/Power-On Brakes — Type SLB and SOB

The SLB and SOB series are shaft-mounted Clutch/Power-On Brake packages that are used to couple two parallel or in line shafts.  The Clutch/Brake package combines the features of our model SL or SO with an FB into one unit for easy installation.  The clutch armature hub accommodates a pulley, gear, sprocket, etc., to transmit torque to the second shaft.  The brake is used to stop or hold the load.  The Clutch/Brake package is shaft mounted and retained by a loose-fitting pin or bracket through the anti-rotation tab.

c-face brakes from inertia dynamics

C-Face, Power-Off Brakes

Inertia Dynamics' Single C-Face Power-Off Brakes are designed to decelerate or hold inertia loads when the power is turned off. The single C-Face mounts on the fan or non-driven end of a motor. Brakes are available from 3 lb.-ft. to 15 lb.-ft.

C-Face Heavy Duty Brakes from Inertia Dynamics

C-Face, Power-Off Brakes with Heavy-Duty Enclosures

Our Single C-Face Power-Off Brake is also available with cast iron housing for applications involving corrosive environments. The heavy-duty housing also includes o-ring seals to create a dust-tight brake. Brakes are available from 3 lb.-ft. to 15 lb.-ft.

Double C-Face Brakes from Inertia Dynamics

Double C-Face, Power-Off Brakes

The Double C-Face Brake is designed for use as a coupler between standard C-Face motors and C-Face gear reducers. An optional foot mount kit is also available with this unit.
