Resize the Motor

By default, the motor dynamometer reference application motor is configured with an 80 kW Flux-Based PMSM motor. Based on desired specifications, you can resize the motor variant for different vehicle applications.

These motor variants are available.

Motor SubsystemVariantDescription
Motor & Inverter Plant

Mapped

Simulate and validate motor system response based on high-level specifications.

Dynamic PMSM

Simulate and validate linear dynamic models based on existing motor details.

Flux-Based PMSM (default)

Simulate and validate nonlinear dynamic models based on existing motor details.

You can use the Virtual Vehicle Composer app to resize your virtual vehicle motor based on high-level specifications. For more information, see Resize Engines and Mapped Motors.

To set the variant and resize the motor, use the dynamometer reference application. After you open the reference application, click one of the Resize buttons:

  • For a mapped motor, click Resize Mapped Motor Model. Then, set the desired maximum power, torque, DC link voltage and constant power speed ratio (CPSR).

  • For a dynamic motor, click Resize Dynamic PMSM and Recalibrate Controller. Then, set the desired maximum power level, DC link voltage, and axial resize factor.

  • For a flux-based motor, click Resize Flux-based PMSM and Recalibrate Controller. Then, set the desired maximum power level, DC link voltage, and axial resize factor.

Click Apply and Resize Motor to resize the motor with your desired specifications. The reference application:

  • Resizes the motor and motor calibration parameters

  • Recalibrates the controller to match the resized motor

  • Saves the motor and controller parameters to the model

Click Plot Characteristics to view characteristics of the new motor.

You can use the variants in other applications, for example, in vehicle projects that require a motor model.
