Emission
Electromagnetic compatibility
Under normal switching conditions with an unfiltered DC voltage via a bridge circuit, the
INTORQ spring-applied brake complies with the EMC standard EN50081, part 1.
Please note that the entire circuit only complies with the EMC Directive, if it is configured
according to one of the following possibilities:

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.
Noises
The switching noises during engagement and disengagement depend on the air gap ”s
Lü
” and
the brake size.
Depending on the natural oscillation after installation, operating conditions and state of the
friction faces, the brake may squeak during braking.
