Siemens SIMOTICS T-1FW6 - Danger from Strong Magnetic Fields

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