Analysis Options

Notes

Calculate Torque

Calculates the torque of the electromagnetic force.

Available for the 2D or 3D static analysis.

Calculate Inductance

Calculates the self-inductance, mutual inductance, and impedance(in the harmonic analysis only).

• See [Inductance Calculation] for details.

• In the static analysis, the setting is fixed with [Calculate Inductance].

• The calculation will take some time. It is recommended to unselect this option unless it is necessary.
  

Calculation Type

Selects a calculation type of inductance from the following.

Apparent Inductance

Differential Inductance

Selection is required if the analysis type is static as well as nonlinear.

For other analysis types, the setting is irrelevant. The results will be the same whichever is opted.

See [Calculation Type of Inductance] for details.

Options

Notes

External Circuit Coupling

Executes a coupled analysis with the external circuit.

Click and launch Circuit Editor to edit external circuit.

Rotating Machinery

Analyzes rotating machinery such as motor and generator.

Refer to [Rotating machinery tab] for detailed setting.

Translational Machinery

Analyzes translational machinery such as linear motor and shaft motor.

Refer to [Translational Machinery tab] for detailed setting.

Calculate the Inductance

Calculates the self-inductance and mutual inductance.

• The calculation will take some time. It is recommended to deselect this option unless it is necessary.

• Calculation type of inductance is not selectable for the transient analysis.
  See [Calculation Type of Inductance] for details.

Partial Model (Symmetric Model) Setting

Sets the partial model (symmetric model).

Setting items are as follows.

• Conversion of the results (Values such as torque which are shown in the table of results)

• Adjustment of the relation between the analysis domain and the external circuit in the external circuit coupling

• Adjustment of the ratio of the analysis domain (symmetric model) and the full model in the motion equation coupling.

Partial Model (Symmetric Model)

Selected if the analysis domain is partial model (symmetric model) such as period symmetric.

Division Numbers (Full model/Partial model)

Sets the number of divisions of the full model. If the the model is quarter symmetric, enter 4.

Conversion of I/O values of External Circuit
[Convert] sets the value of the full model for the external circuit. [Do not convert] uses the value of the partial model.

  If [Convert] and [Convert results to full model for output] are selected, the values related to the external circuit will be converted to the full model for output. Converted values are such as current of components of the circuit, which are displayed on the results table.         If [Convert] is selected, enter the number in[Number of series] and [Number of parallels] for coils on the external circuit.

  See [Example of External Circuit Conversion Setup] for the details.

  See also [External Circuit Conversion].

Convert Results to Full Model for Output

Converts the results (values such as torque which are shown in the result table) to the full model for output.

In the case of 2D quarter symmetric model for example, the torque value is obtained by [torque value of the quarter model x model thickness x number of divisions of the full model].

Fundamental Frequency (for determining one period and iron loss calculation)

Used to determine one period of the electric angle and calculate the iron loss.

Available only for the transient analysis.

• One period of the electric angle is used for calculating average torque, loss, and efficiency.
  One period of electrical angle is calculated as 1/fundamental frequency.

• See [Iron Loss tab] for the iron loss calculation.
  

Frequency of Power

Automatically referred to.

Not available for the DC power.

It is determined by the setting on the [Current] tab in the body attribute.

Specify Frequency

The fundamental frequency is specified manually.

Calculate from the number of poles and rotations

The number of poles and rotations of the rotating machinery are used for calculation.

Enter the number of poles.

The number of rotations on the [Rotating Machinery] tab is referred to.
