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 electro-
magnetic fields occur in operation.
Components with permanent magnets
The rotors of the 1FW6 built-in torque motors described in this manual contain permanent
magnets.
