Danger from strong magnetic fields

Occurrence of magnetic fields
Motor components with permanent magnets generate very strong magnetic fields. In the no-
current condition, the magnetic field strength of the motors comes exclusively from the
magnetic fields of components equipped with permanent magnets. Additional electromagnetic
fields occur in operation.
Components with permanent magnets
The rotors of the 1FW6 built-in torque motors described in this manual contain permanent
magnets.

Risk to persons as a result of strong magnetic fields
Risk of death as a result of permanent magnet fields
The permanent magnets in the motors represents a danger for people with active medical
implants, who come close to the motors. This is also the case when the motor is switched off.
Examples of active medical implants include: Heart pacemakers, insulin pumps.
• If you are affected, stay a minimum distance of 300 mm from the permanent magnets
With regard to the effect of strong magnetic fields on people, in Germany the DGUV
regulation 103-013 "Electromagnetic fields" of the German Social Accident Insurance must
be complied with! This regulation lists all of the requirements that must be observed at
workplaces. In other countries, the relevant applicable national and local regulations and
requirements must be taken into account.
