FAE

Product catalog summary

Overview: The document provides technical specifications and assembly instructions for the EIDE type FAE electromagnetic brake. It details the components, operation, and installation procedures for different constructions of the brake.

Specifications: The brake consists of an induction core with a built-in coil and friction material, and an induced unit with a disc or plate and a membrane-spring. It operates at a standardized voltage of 24 V.D.C. and is available in various sizes with maximum torque ranging from 0.15 to 70 Nm and maximum revolutions per minute from 1,400 to 10,000.

Operation: When voltage is applied, a magnetic field attracts the induced disc, causing deformation in the membrane-spring and resulting in friction that initiates braking. Removing the voltage stops the braking action without residual torque.

Installation: The brake can be mounted directly onto a pulley, chain pinion, or shaft. The dimension 'a' must be considered during installation. Parts must be centered using screws, and friction surfaces should be free from grease or oils to ensure optimal braking torque.

Technical Data: The document includes detailed tables with dimensions and technical data for different constructions (1.1, 1.2, 1.3), including mass, inertia, airgap, and various dimensional parameters. Keyways are according to DIN 6885 standards.

Recommendations: Ensure friction surfaces are clean and allow for a certain number of operations before the torque reaches its nominal value. The document also provides contact information for further inquiries.

ELECTROMAGNETIC BRAKE ASSEMBLY EXAMPLES SINGULAR PLANE SINGLE-DISK Type FAE Construction 1.2 Adaptation to shaft The electromagnetic brake EIDE type FAE is mainly composed of an induction core, with the corresponding built-in coil and friction material, and of the induced unit, composed of the induced disc or plate itself with a membrane-spring (in construction 1.1 - to be mounted directly onto pulley, chain pinion, etc.) and of the induced support bushing (in constructions 1.2 and 1.3 - to be mounted onto the shaft on which we want to exert the braking action), the induction core is centered with regard to the shaft and is adjusted to the bedframe of the machine. The dimension “a” –which is given in the table– will have to be taken into account during the mounting procedure. When applying voltage (standardized at 24 V.D.C.) to the coil, a magnetic field is built up which attracts the induced disc or plate, causing thus a deformation within the membrane-spring, which is compensated by gap “a”, leading to the friction between them that causes the breaking. When cutting out the voltage, part 5 recovers its original position, whereby the braking action is stopped without residual torque. Construction 1.3 Adaptation to shaft Care must be taken so that both friction surfaces are free from grease or oils, as their presence reduces the braking torque. These units require a certain number of operations before the torque reaches its nominal value. In construction 1.1, parts 4-5 have to be mounted centered only by means of the screws themselves. The centering procedure can not be carried out by restraint. The pulley, pinion or bushing to which it is coupled has to be provided with some bores which must be approx. 30% bigger than the rivet heads 6 (their dimensions are shown in the table) to hide them.
