In Freud's psychodynamic theory, the three major systems of personality are the id, ego, and superego. The id represents the primal, unconscious drives and desires, the superego embodies moral standards and ideals acquired from society, and the ego functions as the mediator between the id and superego, balancing desires with reality.

The self, on the other hand, is not identified as a distinct component within Freud's framework. While the concept of self is significant in various psychological theories, particularly in humanistic and cognitive psychology, it does not align with Freud's specific structural model of personality. Instead, Freud emphasizes the interactions among the id, ego, and superego as critical to understanding human behavior and personality development. Thus, the correct identification of what is not part of Freud's model is indeed the self.
