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.
