Defining the General Data for a Brushless PMDC Motor

Use the General window to specify the rated output power, voltage values, circuit type, and speed of the brushless DC motor.

To define the general data:

1. To open the General Data Properties window, double-click the Machine entry in the Project Manager tree on the desktop. (You can also enter values in the Properties section of the desktop without opening a separate window.)
2. Enter the number of poles for the machine in the Number of Poles field. This value is the total number of poles in the stator (or the number of pole pairs multiplied by two).
3. Enter the energy loss due to friction at the given speed in the Frictional Loss field.
4. Enter the wind loss due to air resistance measured at the reference speed in the Wind Loss field.
5. Enter the given speed in the Reference Speed field.
6. Select DC or CCC from the Control Type drop-down menu.
7. Select a Circuit Type from the following types:

   Y3	Y-connected, three-phase
   L3	Loop-type, three-phase
   S3	Star-type, three-phase
   C2	Cross-type, two-phase
   L4	Loop-type, four-phase
   S4	Star-type, four-phase

The circuit types are based on industry standards. By default, type Y3, a three-phase, six-status circuit, is selected as the circuit type.

Note: When you place the mouse cursor over a circuit type, an outline schematic of the circuit appears.
8. Click OK to close the Properties window.
