Basic knowledge about the motor

 

10. The current in the excitation winding of the synchronous motor is DC. The excitation mode mainly includes excitation of the excitation generator, excitation of the static rectifier, and excitation of the rotary rectifier.

 

11. There are no even harmonics in the three-phase synthetic magnetomotive force; the symmetrical three-phase winding is symmetrical three-phase current. There are no multiples of three magnetic harmonics in the combined magnetomotive force.

 

12. Three-phase transformers generally want to have a delta connection on one side or a ground point on one side because the winding connection of the three-phase transformer is expected to have a path of the third harmonic current.

 

13. When the symmetrical three-phase winding is symmetrical three-phase current, the fifth harmonic in the synthetic magnetomotive force is reversed; the seventh harmonic is forward.
