Design
The Lenze quality standards for development,
material, selection, production and assembly mean
that the new spring-operated brakes fulfil the
highest requirements. These electromagnetically
released, spring-operated brakes can be used in all
cases where movable masses have to be braked in
the shortest possible time or have to be hold in a
defined position.
The braking force is provided by compression
springs. This means that the frictional brake torque
is produced in the non-current state, i.e. also in the
event of a supply failure. The brakes are released
electromagnetically.
The new BFK458 range replaces the spring-
operated brake types 14.448 / 14.449 and 14.450.
The main components of the new modular system
consists of the modules E (adjustable brake torque)
and N (brake torque not adjustable). This system
offers flexibility by combining the basic modules
with further modular elements to cover the widest
possible range of applications. This catalogue will
assist you in selecting and ordering your spring-
operated brake fast and easily.

Principle of operationSpring-Operated Brake BFK458
11Federkraftbremse BFK458 en 07/2003
Spring-operated brakes BFK458 are brakes with two friction surfaces. By means of several pressure springs the brake friction is generated when no current is applied.The brakes are electromagnetically released. While braking,the rotor (3) which is axially movable on the hub (4), ispressed against the counter friction face (6) by means ofthe springs (2) via the armature plate (1). In case of braking,
an air gap slü occurs between the armature plate and thestator (7). To release the brake, the coil of the stator (7) isexcited by means of DC current.
The resulting magnetic flux causes the armature plateto be pulled towards the stator. Thus, the rotor is released.The brake torque can be reduced via the adjuster nut (8) forthe basic module E.

Standard brake torque
Depending on the individual application, the graduated torques listed in the table are available. A pole shim (brass film) must be placed between stator and armature
For the basic module E, the brake torque can be reduced by turning the detended adjuster nut in the stator. Theadjuster nut can be unscrewed until the maximumdimension h1max (see table on page 14).
Take into consideration that engagement times and disengagement times change depending on the braketorque. The reduction of the torque is independent of thechoosen brake torque.

Double brake (double brake torque), suitable for stage machinery and lots of other application fields
Noise-reduced designs
The required noise reduction for stage machinery andvarious other application examples can be optionally achieved by 2 measures:
1. Impact noise reduction of the armature plateThe operating noise can be minimised by using O-rings,which are installed between the magnet housing and armature plate, acting as a limit stop damper.
2. Noise-reduced aluminium rotorRattling noises, which can occur e.g. at load changes in therotor-hub connection, are reduced by using a rotor withplastic sleeve.

Installation
If no suitable opposing surface is available, a mountingflange or a friction plate (6) can be used.˘ fit the hub (4) onto the shaft (5) and secure axially˘ now fit rotor (3) onto hub (4)˘ insert the fixing screws (10) through the holes provided
in the stator and fit those to the counter friction surface˘ remove transport clips˘ check air gap slü˘ the friction surfaces must be kept from oil and grease˘ connect electrically
Life
The brake has to be adjusted when reaching slümax. The necessary friction work depends on a number of factors, namely the inertia to be braked, the braking speed,the operating frequency and thus the temperature at thefriction faces. Therefore, no general statement can be madeabout the friction work available until adjustment, which isvalid for all operating conditions. For more detailed infor-mation, please indicate the specific operating conditions. (Please contact the manufacturer).
slü
Hand releaseThe hand release serves to release the brake manually. Itcan also be retrofitted. The hand release goes back to itsbase position automatically after operation. The releasescrews are carried in ball joints and are only tensioned. Theair gap „s“ is the distance between the armature plate (1)and the washer (15). The dimension „s“ must be maintained when assembling the hand release.
Caution:Even with a reduced rated torque, a readjustment of theworking air gap reaching the dimension slümax is necessary for reasons of safety.
FlangeIf no suitable friction surface is available, the mountingflange can be used, which at the same time is able to carrythe seal.

Friction plateIf plain machined counterface is available but cannot beused as a friction surface, for example in the case of aluminium, we recommend to use a friction plate whichcan also be combined with a seal. The friction plate ismade of non-corroding material. It can be supplied up tosize 16.
Centring flange (Tachometer brake)The basic module N combined with a centring flange is suitable for the assembly of a tachogenerator.
Mounting flange (double brake)The mounting flange can be used to adapt a second basicmodule to the basic module N; the resulting double brakeis suitable for stage machinery or other applications withincreased safety requirements.
SealThe seal prevents to a large extent exit or penetration ofdust, humidity, dirt, etc. into the braking area. The seal ispulled over the brake and inserted into the grooves provided. If no suitable groove is available at the outputside, we recommend to use a mounting flange or a frictionplate.

AccessoriesBrake Cover and Microswitch
21Federkraftbremse BFK458 en 07/2003
Microswitch
The microswitch is used when a monitoring of the air gapis required and is available for the sizes 12-25. If the armature plate (1) is in contact with the stator (7), themotor contactor is controlled via the microswitch. Themotor can only start, if the brake is released. If the maxi-mum air gap slümax is reached, the stator no longer attractsthe armature plate. The motor contactor is not activated,the motor does not start.
The air gap slü of the basic module E and the basicmodule N can be readjusted. The microswitch can also be adjusted such that a signal is output before the wearreserve is reached (wear monitoring).
As an option, a cover can be mounted to the basic module E and N to protect the brake from water and dust(enclosure acc. to IP65). This design is not available in conjunction with a hand release.

AccessoriesMicroswitch and terminal box
22 Federkraftbremse BFK458 en 07/2003
Terminal box
The connecting cables can easily be integrated into higher-level control systems via the terminal box (brake sizes 12-25) to achieve different wirings (three inputs/outputs).2/4-pole terminal strips, half wave and bridge rectifiers anda microswitch can be integrated into the terminal box.
Door drives, for instance, are provided with brakes withhand release and microswitch for hand release monitoring. In this case, the hand release must make itpossible to drive the door also in manual operation to thedesired position, e.g. with a crank. The manual operationmust be detected via a microswitch. Its operating signalmust be combined with the motor control, so that startingof the motor and as a result possible injuries of the operator can be prevented. The microswitch for hand release monitoring is a built-on option.
The fixing bracket is screwed on the magnet housing ormagnet part via the bores on the backside. The fixingbracket makes it possible to mount a microswitch. Bothdirections of release, towards and away from the motor can be realised through different fixing brackets andadjustments of the microswitch.

SelectionBasic Information
28 Federkraftbremse BFK458 en 07/2003
The necessary size of a brake is largely determined by therequired brake torque Mreq.
The inertias to be braked, the relative speeds, the braking times and the operating frequency also have to be considered in the calculations. Marginal conditions, e.g.ambient temperature, humidity, dust and mountingposition should be known. In the event of extreme/criticalconditions, please contact the manufacturer. Selection inaccordance with the VDI rule 2241.
In any case, the friction faces must be kept from oil andgrease.
For explanations for the terms used in the calculationsplease refer to the explanations of symbols on page 9.
Safety factorTo ensure the necessary transmission safety even underextreme operating conditions, the required torque is multiplied by the safety factor K which depends on the operating conditions.

Thermal loadFor high operating frequencies and friction work per operation, the thermal load of the brake must be considered.The friction work per operation can be calculated as follows:
- ML = to be used, e.g. when lowering a load+ ML = for normal braking
The permissible friction work per operation at a given operating frequency can be taken from the diagrams onpage 18. With given friction work per operation, the permissible operating frequency can be taken from the diagrams mentioned above.
