Setting Up Analysis Parameters for a Line-Start PM Synchronous Motor

To define the solution data:

  1. To open the Solution Setup window, right-click Analysis in the Project Manager tree, and click Add Solution Setup.
  2. Click the General tab. The Operation Type is automatically set to Motor for this machine type.
  3. Select the Load Type used in the motor from the following options:

    Const Speed

    The speed remains constant in the motor.

    Const Power

    The output power remains constant in the motor.

    Const Torque

    The torque remains constant regardless of the speed. In this case, Tload = Trated, given by the output power divided by the given rated speed.

    Linear Torque

    The torque increases linearly with speed. In this case, Tload = Trated * (n/nrated) where Trated is given by the output power divided by the given rated speed.

    Fan Load

    The load varies nonlinearly with speed. In this case, Tload = Trated * (n/nrated)2 where Trated is given by the output power divided by the given rated speed.

  4. Enter the output power developed at the shaft of the motor in the Rated Output Power field.
  5. Enter the RMS line-to-line voltage in the Rated Voltage field.
  6. Enter the desired output speed of the motor at the load point in the Rated Speed field.
  7. Enter the temperature at which the system functions in the Operating Temperature field.
  8. Click the Line-Start PM Synchronous Motor tab.
  9. Select Wye or Delta from the Winding Connection drop-down menu.
  10. Click OK to close the Solution Setup window.
