Electromagnetic compatibility
Note!
The user must ensure compliance with EMC Directive 2004/108/EC using
appropriate controls and switching devices.
If an INTORQ rectifier is used for the DC switching of an INTORQ spring−applied brake and
if the operating frequency exceeds five switching operations per minute, the use of a
mains filter is required. If the INTORQ spring−applied brake uses a rectifier of another
manufacturer for the switching, it may become necessary to connect a spark suppressor
in parallel with the AC voltage. Spark suppressor according to coil voltage on request.
Heat
Since the brake converts kinetic energy as well as mechanical and electrical energy into heat,
the surface temperature varies considerably, depending on the operating conditions and
possible heat dissipation. Under unfavourable conditions, the surface temperature can reach
130
_
C.
Noise
The switching noise during engagement and disengagement varies depending on the air gap
"s
Lü
" and the brake size.
For switching on the AC side, the switching noise is between approx. 45 and 55 db (A).
Depending on the natural oscillation after installation, operating conditions and state of the
friction faces, the brake may squeak during braking.
Others
The abrasion of the friction parts produces dust.
In case of high load, the friction face will become so hot that odours may occur.
