*ELECTRIC MACHINE LOAD

Define electromagnetic forces loads for an electric machine.

This option is used to define electromagnetic force loads for an electric machine. These forces are usually the result of a previous electromagnetics simulation and are changed to Abaqus loads internally.

Data lines to define an electric machine load

First line

  1. Rotational speed (revolutions per time) at which the electrical machine operates.

  2. Mechanical torque at which the electrical machine operates.

  3. Electric machine magnet temperature.

Second line, which defines the eccentricity orientation

  1. X-coordinate of point a.

  2. Y-coordinate of point a.

  3. Z-coordinate of point a.

  4. X-coordinate of point b.

  5. Y-coordinate of point b.

  6. Z-coordinate of point b.

  7. X-coordinate of point c.

  8. Y-coordinate of point c.

  9. Z-coordinate of point c.

Third line, which defines the rotor orientation

  1. X-coordinate of point a.

  2. Y-coordinate of point a.

  3. Z-coordinate of point a.

  4. X-coordinate of point b.

  5. Y-coordinate of point b.

  6. Z-coordinate of point b.

  7. X-coordinate of point c.

  8. Y-coordinate of point c.

  9. Z-coordinate of point c.

Fourth line to define the electromagnetic forces

  1. Radial force magnitude.

  2. Radial force phase shift in radians.

  3. Tangential force magnitude.

  4. Tangential force phase shift in radians.

  5. Torque correction magnitude.

  6. Torque correction phase shift in radians.

  7. Time order of the forces and the torque.

  8. Spatial order of the forces and the torque.

  9. Slice number on which the forces and the torque are specified.

Repeat this data line as often as necessary to define different forces and torque for each spatial and temporal order in each slice.
