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 AC voltage is
applied. 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). Spring-applied single-disc brakes with firedamp
protection are characterised by the fact that all components that may ignite explosive mixtures are placed in
an enclosure. This enclosure is designed to withstand the specified test pressure in case the mixture
explodes inside the enclosure. It also ensures that mixtures outside the enclosure are not affected by the
explosion. To ensure reliable firedamp protection, the cable entry of the spring-applied single-disc brake is
equipped with a special threaded entry sleeve.
2.2 Structure
The solenoid housing (1.1) of the spring-applied single-disc brake accommodates the firmly fitted field coil
(1.2) with flying leads. The flying leads are connected to the connecting terminal (19) inside the connector
box (25). The flange (3) and friction plate (33) are screwed to the solenoid housing (1.1) by means of
machine screws (22). The cover (7) is fixed to the solenoid housing (1.1) by means of machine screws (20)
to obtain a pressure-sealed assembly. Owing to the spring force generated by the compression springs (4
and 35), the friction disc (5) is pressed over the armature (2) against the friction plate (33) and flange (3) to
generate the braking effect of the spring-applied brake. The friction disc (5) and hub (17), which constitute
the rotating part of the spring-applied brake, are connected with the shaft to be braked. The friction disc (5)
features a square socket and can be moved on the hub (17) in axial direction. Spacer sleeves (6) are
provided to allow the air gap 's' to be adjusted. The customer-specific connecting cable can be fed into the
connector box (25) through a cable entry sleeve (30). When AC voltage is applied to the built-in bridge
rectifier of the spring-applied single-disc brake, the spring force is overcome by the dynamic effect of the
electromagnetic field. This causes the armature (2) to be released and the braking effect to be neutralised.
The shaft to be braked is not exposed to any axial force by the brake. The spring-applied single-disc brake is
equipped with a redundant thermoswitch system (2x2 thermoswitches) (11 and 12) and with a microswitch
(13) 1). The microswitch (13) is provided to prevent machine (e.g. motor) start-up before the brake has been
released. The four (2x2) thermoswitches (11 and 12) are connected in series with the microswitch (13) and
interrupt the control circuit of the machine (e.g. motor) as soon as the maximum permitted brake temperature
is exceeded. When using brakes with hand release (29), openings must be provided in the part enclosing the
brake (e.g. fan cover) to allow the hand release lever to be installed. The hand release (29)
2) allows the
brake to be released manually (e.g. in case of power failure).

3. Installation
3.1 Mechanical installation
The spring-applied single-disc brake must be slipped with its hub (17) onto a
shaft (tolerance h6) provided with a feather key to DIN 6885, sheet 1. As the
hub (17) is firmly fitted to the brake, it need not be axially secured on the
machine shaft (e.g. motor shaft). Make sure that no radial forces act on the
deep groove ball bearing (18) during installation and operation (vertical
installation, if possible) and that the hub (17) is not exposed to any
permanent axial force (e.g. exerted by shaft shoulder) after installation has
been completed. The spring-applied brake is centred by means of the deep
groove ball bearing (18) of the hub (17). Fixing screws (10) are provided to
allow the spring-applied single-disc brake to be screwed to the fixing surface
(8) of the machine (e.g. motor). Before starting installation work, the O-ring
(16) must be inserted into the corresponding groove provided in the solenoid
housing (1.1). Make sure the fixing screws (10) are tightened evenly in
diametrically opposite sequence and that the specified tightening torques
(see Table 7/1) are not exceeded.
Note!
Make sure that the deep groove ball bearing (18) is not distorted during installation of the spring-applied
single-disc brake and that the shaft rotates easily when the brake is released. Check that no grinding sounds
can be heard.

Table 7/1: Hub dimensions (17); tightening torques of fixing screws (10)
Check that the fixing surface (8) meets the following requirements before installing the brake:
•Axial runout relative to the shaft end to DIN 42955-N (measuring radius = reference circle)
•Material: steel, cast iron, aluminium – with excellent thermal conductivity
•Absence of oil and grease
Radial runout of the shaft end relative to the fixing surface (8) to DIN 42955-N
Attention!
The specified axial runout of the fixing surface (8) relative to the shaft end and the specified radial runout of
the shaft end relative to the fixing surface (8) must be strictly observed in order not to reduce the reliability
and service life of the spring-applied single-disc brake. Before installing the brake, the shaft end must be
slightly brushed with a high temperature grease (e.g. Copaslip). This is essential to allow the brake to be
easily removed if maintenance work needs to be carried out at a later date.
Attention!
The MAtightening torque specified for the fixing screws (10) must be strictly observed. The screws (10) must
be tightened evenly in diametrically opposite sequence.

3.2 Installation of the hand release (29) (brakes types with hand release)
The lever of the hand release (29) must be inserted into the square socket of the two cams (29.1) which are
firmly fitted to the circumference of the solenoid housing (1.1). Make sure the lever is correctly positioned.
The mechanical release forces F and the maximum permitted release forces (actuation forces) Fmax are
specified in Table 8/1.
Note!
Machinery-specific regulations and requirements (e.g. for hoists, cranes and elevators) must be observed
when using brakes with hand release (29). The hand release (29) must not be used to release the brake
during normal operation.
Caution!
The brake torque can be neutralised manually by means of the hand release feature (29). Consequently, the
brake must be installed in such a way that any unintentional actuation of the hand release (29) is excluded
and reliable brake operation is ensured.

Table 8/1: Release force F, max. permitted release force Fmax of hand release (29)
Warning!
Check that the mechanical hand release (29) is in a central position (see Fig. 6/1) when not in use. This is
crucial to ensure reliable brake engagement. Otherwise, the full braking effect of the spring-applied single-
disc brake may not be reached. In this case, the machine (e.g. motor) must be stopped immediately and
must not be restarted until correct operation of the hand release (29) and automatic return of the hand
release lever in its central position (see Fig. 6/1) has been ensured.

Kendrion Binder Magnete GmbH Operating Instructions 76 ..P..B00 Last updated: 30 Dec. 2009 Page 9
3.3 Electrical connection and operation
The spring-applied brake
must be connected to an
AC power source via
jumpers 1 (BA1) and 2
(BA2) on the connecting
terminal (19) (see Fig.
9/2). The customer-
specific connecting cable
must be connected to the
terminal (19) by means of
a special cable entry
sleeve (30). Remove the cover (26) of the connector box
(25) so that the individual strands of the connecting cable
can be connected to the terminal. The threaded cable
entry sleeve (30.1) of the sleeve assembly (30) is factory-
fitted to the solenoid housing (1.1) (see Fig. 9/1). Tighten
the threaded entry sleeve (30.1) to secure the customer-
specific connecting cable. The sealing ring (30.2) seals the cable entry. Tighten the machine screws (30.3) to
strain-relieve the connecting cable (cable diameter 17…19 mm). The clamping strap (30.4) locks the
threaded cable entry sleeve (30.1) in its position so that it cannot rotate. After completion of these steps, the
cover (26) of the connector box (25) must be reinstalled.
Attention!
When fixing the cover (26) to the connector box (25), the MAtightening torques of the machine screws
specified in Table 13/1 must be strictly observed. The flat seal (9) and spring washer (28) must be installed
as shown in Fig. 6/1.
The supply voltage is rectified by the built-in bridge rectifier. Depending on the brake size and torque, voltage
ripple due to intermittent power supply may cause brake humming or incorrect brake operation. Perfect
brake operation must be ensured by the user or system manufacturer by providing suitable electrical
controls.

3.3.1 AC power supply
Direct connection of the spring-applied single-disc brake to an AC power source is only possible if a rectifier
is used. Wiring of the brake in case of single-phase AC power supply must be performed in the same way as
with three-phase voltage. The coupling times vary depending on the switching type (DC side switching or AC
side switching).
Bridge rectification:
Bridge rectifiers provide voltage with minimum residual ripple. This allows brake humming to be avoided
even if small size brakes are used. In case of bridge rectification, the U2coil voltage is lower by factor 0.89
than the rectifier input voltage.
AC side switching:
In case of AC side switching, the switching contact for the spring-applied single-disc brake is provided on the
AC voltage side directly before the bridge rectifier. It must be considered, however, that the bridge rectifier
with its free-wheel diode may extend the coupling time significantly (by factor 5 or over) after AC voltage has
DC side switching:
In case of DC side brake switching, an auxiliary contact is provided on the brake contactor, for example. This
auxiliary contact is designed to interrupt the power supply on the DC side. The jumper on the connecting
terminal (19) (see Fig. 9/2) must be replaced by the auxiliary contact. In case of DC side switching, AC side
switching is also required.
