behavior is comparable to that of electrically excited synchronous motors.
Field of application
Permanent-magnet synchronous motors are used together with converters as slowly running
direct drives, e.g., for
● Pulp and paper
● Steel industry
● Plastics industry
● Marine
1FW4 drives must not be operated:
