develop, resize, and calibrate motors with dynamometer test harness

the motor dynamometer reference application represents a motor plant and controller connected to an ac dynamometer. using the reference application, you can design and test traction e-motors and controllers for your electrified powertrain vehicle. to create and open a working copy of the motor dynamometer reference application project, use this command.

by
        default, the reference application is configured with an 80 kw flux-based pmsm motor.
you can configure the reference application project for different dynamometer control
        modes. to implement the operating modes, the reference application uses variant
        subsystems.
this table summarizes the dynamometer tests.

run performance tests
run dynamic and steady-state performance tests at different
                                operating points of torque and speed.
dynamometer controller commands a series of motor speeds and
                                torques to the motor controller. at each quasi-steady-state
                                operating point, the experiment records the motor plant model output
                                and the controller commands for the current calibration
                                parameters.

motor system
the reference application includes variant subsystems for mapped (steady-state),
            dynamic pmsm, and flux-based pmsm motors.
objectivemotor variant
simulate and validate motor system response based on high-level
                                specifications.
mapped
simulate and validate linear dynamic models based on existing
                                motor details.
dynamic pmsm
simulate and validate nonlinear dynamic models based on
                                existing motor details.
flux-based pmsm
performance monitor
the reference application contains a performance monitor block that you
            can use to plot steady-state and dynamic results. you can plot:


  • steady-state results as a function of one or two variables.
  • dynamic results using the simulation data inspector.
