Rotating machine components: definition (structure)

Definition

A squirrel cage or brush-segment component is defined by:

  • a name (and a comment)
  • a model
  • specific characteristics depending on the model
  • one terminal (squirrel cage) / two terminals (brush-segment)

Name

The name permitting the identification of the component is given by the user when it is created by him.

A comment (optional) can be added to the name.

The name and the comment are displayed by default in the graphic zone close to the symbol.
