1. General information
1.1 Introduction
These Operating Instructions describe the operating principle and features of spring-applied single-disc brake
types 77 600..A00, 77 600..A20, 77 600..K00 and 77 600..K01. The safety information provided in this manual
must be strictly observed during the set-up of the machine (e.g. motor) and during the start-up, operation and
maintenance of the spring-applied brake.
Should any queries arise with respect to torques, torque variations, installation position, wear, wear reserve,
switching work, break-in conditions, release range, ambient conditions and the like, please contact Kendrion
(Villingen) and ask for clarification before starting to use the brake. Spring-applied single-disc brakes are not
ready-to-use devices, but are intended to be incorporated into or assembled with other equipment.
Consequently, they will be referred to as components in the following sections.
1.2 Standards and directives
The state-of-the-art spring-applied brakes have been designed, built and tested in accordance with the
requirements of DIN VDE 0580 concerning electromagnetic devices and components.
Being classified as "electromagnetic components", spring-applied brakes are also subject to the Low Voltage
Directive 2014/35/EU. The user is required to employ suitable switching devices and controls to ensure use of
the brakes in accordance with EMC Directive 2014/30/EU.
1.3 Declaration of Incorporation (in accordance with Annex II, part 1, Section B of Machinery
Directive 2006/42/EC)
We hereby declare that the products below comply with the essential health and safety requirements specified
in Annex I of Machinery Directive 2006/42/EC:
Annex I General Principles and Sections 1.1.2, 1.1.3, 1.1.5, 1.3.2, 1.5.1
The partly completed machinery must not be put into service until the final machinery into which it is to be
incorporated has been declared in conformity with the provisions of Machinery Directive 2006/42/EC. The
relevant technical documentation required for the partly completed machinery has been compiled in
accordance with Annex VII, part B of Machinery Directive 2006/42/EC. The manufacturer undertakes to submit
an electronic copy of the relevant technical documentation compiled for the partly completed machinery if
reasonably requested by national authorities.

2. Product description
2.1 Operating principle
The spring-applied single-disc brake is designed to operate dry. The force generated by an electromagnetic
field is utilised to overcome the braking effect produced by the spring force. The spring-applied single-disc
brake engages in unpowered condition and releases when DC voltage is applied. Brakes equipped with a built-
in rectifier (half-wave or bridge rectifier) can be connected directly to an AC power source. The form-fit
connection between the friction disc and hub and the connection of the hub with the machine shaft (e.g. motor
shaft) ensure that the torque generated by the spring-applied single-disc brake (brake torque) is reliably
transmitted to the machine (motor). The brake can also be equipped with an optional hand release to allow the
brake to be released manually.
2.2 Design
The solenoid housing (1.1) of the spring-applied single-disc brake accommodates the firmly fitted field coil
(1.2) with the connecting cable resp. at brakes with a connector box (25) whose connecting terminals are
located in the connector box (25). The solenoid housing (1.1) also includes the compression springs (3) which
press the friction disc (5) over the armature (2) against the friction plate 1) (10) and flange (11) to generate the
braking effect of the spring-applied brake. The air gap 's' is determined by the position of the intermediate ring
(6). The friction disc (5) features a square socket and can be moved on the hub (17) in axial direction. The
customer-specific connecting cable can be fed into the connector box (25) through a cable gland (14) (PG 11).
When DC voltage is applied to the field coil (1.2) of the spring-applied single-disc brake, the spring force is
overcome by the electromagnetic field force. This causes the armature (2) to be released and the braking
effect to be neutralised. The shaft to be braked is not subjected to any axial force by the brake. When using
brakes with hand release (21), openings must be provided in the part enclosing the brake (e.g. fan cover) so
that the hand release lever can be installed. The hand release (21) allows the brake to be released manually
(e.g. in case of power failure). When the brake is equipped with a microswitch (19), the microswitch prevents
any start-up of the machine (e.g. motor) before the brake has been released. Thanks to the centring diameters
on the flange and housing sides (diameters d2and d7), the spring-applied single-disc brake is ideal for
applications with mounted transmitters (e.g. tachometer generators, encoders, etc.) after the cover (9) has
been removed.
