Danger from strong magnetic fields
Occurrence of magnetic fields
Strong magnetic fields occur in the components of the motor that contain permanent
magnets. The magnetic field strength of the motors results exclusively from the magnetic
fields of the components with permanent magnets in the de-energized state. Electromagnetic
fields also occur during operation.
Components with permanent magnets
CAUTION
The permanent magnets of the 1FW6 torque motors are located in the rotor.
