Creating the Reports

To assess the solution, you create three plots to record the magnetic flux linkage, magnetic torque, and ohmic heat power produced by the various components of the axial flux motor. To see how the magnetic torque and ohmic heat varies as the rotor moves, you set up a report that calculates the position of the rotor.

  1. Set up the electromagnetic reports:
    1. Right-click the Reports node and select New > Electromagnetism > Magnetic Flux Linkage.
    2. Repeat the previous step, however select Magnetic Torque.
    3. Rename Reports > Magnetic Torque 1 to Magnetic Torque - Rotors and Magnets.
    4. Select the Magnetic Flux Linkage 1 node and set Parts to Parts > Stator Parts > Coils.
    5. Select the Magnetic Torque - Rotors and Magnets node and set the following properties:
      Property Setting
      Axis [1.0, 0.0, 0.0]
      Parts Regions > Motion Specification: Rotation > Magnets and Regions > Motion Specification: Rotation > Rotor
  2. Define the Ohmic Heat power report:
    1. Right-click the Reports node and select New > User > Volume Integral.
    2. Rename Volume Integral 1 to Ohmic Heat Power.
    3. Select the Ohmic Heat Power node and set the following properties:
      Property Setting
      Field Function Specific Ohmic Heat Source
      Parts Regions > Motion Specification: Rotation > Magnets
  3. Create a parameter to calculate the rotation rate of the motor:
    1. Right-click the Automation > Parameters node and select New > Scalar.
    2. Rename Parameters > Scalar to RR.
    3. Select the RR node and set Value to ${omega}/${Pole Pairs}.
    The rotation rate expression used divides the angular velocity (omega) by the number of pole pairs on the axial flux motor. For this particular motor, there are 10 poles so 5 pole pairs. For this case a rotation rate of 20 rps is used.
  4. Define the report for the rotor position:
    1. Right-click the Reports node and select New > User > Expression.
    2. Rename Expression 1 to Rotor Degree.
    3. Select Reports > Rotor Degree and set the following properties:
      Property Setting
      Definition ${RR}*${Time}
      Dimensions Angle

      When the rotation rate is multiplied by time, you are left with the distance the rotor has moved with respect to 2 π .

  5. Multi-select all four reports.
  6. Right-click one of the selected nodes and select Create Monitor and Plot from Report.
  7. In the Create Plot from Reports... dialog, select Multiple Plots (one per report).
  8. Select the Monitors > Magnetic Flux Linkage 1 Monitor node and set Value Type to Part Values.
  9. Select the Magnetic Flux Linkage 1 Monitor > Parts node and set Parts to CS4.
  10. Multi-select the Plots > Magnetic Torque - Rotors and Magnets Monitor Plot and Ohmic Heat Power Monitor Plot and set the following properties:
    Property Setting
    X-Axis Monitor Rotor Degree Monitor
    X-Axis Monitor Units deg
  11. Select the Ohmic Heat Power Monitor Plot > Axes > Left Axis node and set Maximum to 60.0.
  12. Save the simulation.
