Inertia Dynamics Electromagnetic Brakes

Electromate carries a variety of electromagnetic power-on & power-off brakes and flange & shaft mounted brakes from Inertia Dynamics. 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. Power-Off Brakes are designed to decelerate or hold an inertial load when the voltage is turned off. When voltage is applied, the friction disc is released and the brake is free of torque. Power-off brakes are best suited for parking brake applications used to hold a load in position, and are ideal for creating brake motor packages for small servo & stepper frame motors. Both types of brakes are offered in flange mount, C-Face and NEMA frame versions.

All Inertia Dynamics standard brakes and spring applied brakes are recognized by Underwriters Laboratories to both U.S. and Canadian safety requirements. 


Inertia Dynamics Brakes We Offer:

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) w/ Output Shaft C-Face

Type MPC

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.

Shaft Mounted Clutches/Power-On Brakes

Type SLB and SOB

Shaft-mounted Clutch/Power-On Brake package used to couple two parallel or in line shafts.  The Clutch/Brake package combines the features of the 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.

Manual Release, Spring Applied Brakes

Type FSBR

A type FSBR015 spring applied brake with a manual release lever. 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. 

Reverse Mounted Spring Applied Brakes

Type FSBR

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.

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.

Spring Applied Brakes

Type SAB

Designed to be engaged and disengaged in a static condition at zero RPM. Best used as a parking brake to hold a load in position.  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.

Power-Off Brakes

C-Face

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.

Power-Off Brakes w/ Heavy-Duty Enclosures

C-Face

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.

Power-Off Brakes

Double C-Face

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.
