BFK458 Spring applied brakes

 
     
 

 

 

To a large extent, the seal prevents the exit or ingress of dust, humidity, dirt, etc., out of or into the braking area.

?        Seal:

The connection flange can be used to adapt a second brake module to brake design ?N?; the resulting double brake is suitable for use in stage machinery or other applications with increased safety requirements.

?        Connection flange (double brake):

?        Centering flange (tacho brake): basic module N combined with a centering flange is suitable for mounting a tachogenerator.

?        Brake cover.

?        Friction plate.

?        Flange.

?        Terminal box.

?        Micro switches used to monitor air gap and wear (sizes from 12 to 25).

?        Different types of corrosion protection and enclosures.

?        Manual release.

?        Non-standard voltages and bores on request.

?        Bridge/Half wave rectifiers for AC voltage from 42 to 555 V.

?        Noise-reduced designs.

?     Options:

 

?        IP 54 enclosure, depending on the specific operating conditions.

?        Designed for dry running.

o       CSA-CUS (UL) design as standard.

o       Manufacture and testing to VDE 0580.

o       The certified ISO 9001 and ISO 14001 quality system provides the basis for consistently high-quality products.

?        Reliable

o       Air gap must be checked depending on the friction energy used.

o       Asbestos-free fiction linings with low rate of wear.

o       Long rotor/hub connection with low rate of wear and a tried-and-tested involute gear.

?        Low maintenance

o       Brakes are designed for 100% duty time (current applied to the brake).

o       The insulation system to temperature class F (155?C) ensures that the winding has a long service life.

?        Durable

o       No fixed bearing is required on the brake.

o       Special machining of the friction surfaces ensures that the rated torques are achieved after very few switching operations without a run-in procedure.

o       Preset air gap, easy and quick mounting.

?        Ready for operation immediately

The product is suitable for use in potentially explosive atmospheres in zone II for stationary operation (holding or parking brake), explosion group II and temperature class T4.

     Aluminum rotor with toothed intermediate ring, both the friction lining and the. tooth system have a low rate of wear.

     Compression springs with guide pins for protection against shearing forces.

     Armature plate with low backlash and reinforced torque support.

o       15x106 reversing cycles of operation.

o       10x106 repetitive cycles of operation.

     Guaranteed service life of brake mechanism:

 

Long Life design INTORQ BFK458-L

 

The motor can only start if the brake is released.

The microswitch is used to monitor the air gap. When the armature plate makes contact with the stator; the motor contactor is controlled via the microswitch.

     Monitoring microswitch option:

     This system offers flexibility by combining the basic modules with additional components to cover the widest possible range of applications.

o       Design ?N? non-adjustable braking torque.

o       Design ?E?:  adjustable braking torque.

     The main components of the new modular system are the two basic modules:

     The INTORQ BFK458 product range replaces the 14.448/14.449 and 14.450 spring-applied brake types.

     The brake is released electromagnetically.

     Since the braking force comes from pressure springs, the braking torque, which is generated by friction, is available when no current is applied even in the event of a mains failure.

     These electromagnetically released spring applied brakes can be used wherever rapid deceleration or controlled holding of moving masses is required.

     The BFK458 spring-applied brake is a standard product that can be used anywhere, but its modular design means it can also be used for special applications. Its versatility is its strength.
