3.3.4 Version and operating modes of the motor in the synchronous version
1FE2 motors of shaft height 180 (1FE218☐) consist of two winding systems, i.e. each motor
has six connecting cables (three connecting cables for each winding system).
Both partial windings are galvanically separated and only weakly coupled magnetically.
This means the motors can be operated in two different ways.
Option 1: Connection of the two windings to one (large) power section and the "classic"
operation of the motor on a CU/NCU.
