Inputs

1. Standard inputs

  1. Line-line voltage, rms

    The line-line voltage supplied to the machine: “Line-line voltage, rms” ( Line-line voltage, rms value ) must be provided.

  2. Slip or Speed mode

    There are two usual parameters to define the working point. It can be defined by the slip “ Slip ” or by the rotor speed “ Speed ”.

  3. Slip

    If the “Definition mode” is “ Slip ”, the value of the machine’s slip must be provided, and the corresponding speed is deduced.

    The slip “s” in the following relations) corresponds to the relative difference between the synchronous speed (N Synch. ) and rotor speed N:



  4. Speed

    If the “Definition mode” is “ Speed ”, the targeted rotor speed must be provided, and the resulting slip is deduced.

  5. Power supply frequency

    The power supply frequency corresponds to the electrical frequency of the stator magnetic field.

  6. Represented coil conductors

    In transient application, it is possible to export a project into Flux environment where the elementary wires will be modeled with solid conductors. The geometry, the meshing and the corresponding electric circuit will be defined to well represent them.

    Three choices are possible:

    • “No”: The coils will be represented with face regions. The elementary wires won’t be represented in the Finite Element model (Flux).
    • “One phase”: The elementary wires will be represented for only one phase. This will allow to compute AC losses for conductors into the first phase. This choice allows to get a good ratio between the quality of results and computation time.
    • “All phases”: The elementary wires will be represented into all the phases

2. Advanced inputs

The list of advanced inputs dedicated to this export are listed below.

For more details please refer to the section 3.7.4 - List of generic advanced inputs.

  1. Number of computations per electrical period

    The default value is equal to 50. The minimum allowed value is 13.

  2. Number of computed electrical periods

    The default value is equal to 2. The minimum allowed value is 1 and the maximum value is equal to 10.

  3. Rotor initial position

  4. Mesh order

    The default level is second order mesh.

  5. Airgap mesh coefficient

    Airgap mesh coefficient is set to 1.5 by default.
