Defining the Rotor Slots for a General DC Machine

To define the physical dimensions of the rotor slots:

  1. To open the Rotor Slot Data Properties window, double-click the Machine > Rotor > Slot entry in the Project Manager tree. (You can also enter values in the Properties pane of the desktop without opening a separate window.)
  2. Optionally, to automatically design the dimensions of slots Hs2, Bs1, and Bs2, select the Auto Design check box. Using this option causes the software to converge to a flux density value of 1.5 Tesla in the rotor teeth.
  3. Enter the available slot dimensions. The following dimensions may be listed, depending on the Slot Type selected and depending on whether or not Auto Design is selected.:
