2.3.2
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
For the segment motors described in this manual, the permanent magnets are located in the
rotor segments.
