Double Rotor Brake

manual-rubine

KEB Combistop brakes provide failsafe spring-set (power-off) brake engagement.
The electromagnetic brakes are electrically released.

HOW THEY WORK

FEATURES

ROBUST DESIGN

KEB DC brakes are designed to last even in the toughest applications.  

 

Multiple springs – each rated for 10+ million cycles.  A magnet coil epoxied in the housing.

The brake operation is very basic – the only moving part is the armature.  No linkages.  No solenoids.  No moving parts to wear and replace.

POWER-OFF BRAKE

KEB Combistop brakes use a redundant spring design to provide power-off failsafe braking.

DYNAMIC OR HOLDING

KEB has two brake offerings rated for dynamic or holding (parking) applications.

 

Holding brakes have a boosted coil with more springs which allows higher brake torque with the capability to e-stop.  

BIG & SMALL

KEB spring set brakes are perfect for small or large applications.  

 

The Combistop product ranges from a few lbin. to 2000 lbft

EASY ADJUSTMENT

The brake’s airgap is easily adjusted via hollow spacers.  The airgap can be readjusted to compensate for lining wear.  

 

This effectively increases the brake’s operating lifetime by 3X.

FLEXIBLE VOLTAGES

KEB brake coils can be wound for whatever the application requires.  

 

12, 24, 48, 105, and 205VDC coils are standard and cover most battery powered and industrial applications.

CONNECTORS

Combistop brakes can be supplied with customer-specified connectors.

OPTIONS

Manual Hand Release

A manual hand release allows the brake to be opened without electrical power.
A locking hand release option is also available.

Microswitch

A microswitch can verify the brake state or monitor lining wear.

Torque Adjustment Ring

A torque adjustment ring allows the torque to be manually adjusted and lowered by up to 50%.

Noise Reduced

The brake incorporates design features to reduce brake actuation noise.

The solution is rated <65dB @ 1 meter. Effectively, more quiet than the gearbox or switching contactors.

IP65 Rating

The brake is fully enclosed and incorporates gaskets and o-rings – Perfect for outdoor or washdown applications.

Double Brakes

Two independent redundant electrical and magnet circuits.

Meets DIN56921 and BGV C1 requirements.

Dust Protection Ring

Economical solution to protect against ingress of dust and debris. Rated IP44.

Prepared for Encoder

The brake can be prepared with tapped holes to allow the direct mounting of a motor encoder or tachometer.

Secondary Friction Surface

A secondary friction surface provides a suitable counter-rotation surface to prevent wear on the mounting device. It can also incorporate a custom bolt circle for the application.

Connectors

Special connectors can be added per the customers specification.

Conduit Box

A terminal box or conduit fitting can be added for terminal wiring.
