ASM Motor

Electric motor simulation for battery-electric vehicles and all kinds of drive systems

Motor models for highly realistic simulation of various drive and generator concepts to test control software in the virtual world. The testing can be performed on software or hardware platforms in real-time or faster.


Application Area: Electric Drives and Motors

Drive systems are widely used in a large number of industrial and consumer applications like factories, transportation systems, textile mills, fans, pumps, robots etc. Their precise simulation helps developers to advance the control software and validate controllers. ASM Motor is perfect for this. You can just pick whatever kind of motor concept you want to simulate from the library. ASM Motor features the following plant models that already come together with controller models and inverter models to close the loop and get started right away:

Electric Machines

  • Separately excited DC machine
  • Brushless DC motor (BLDC)
  • Squirrel cage induction motor (SCIM)
  • Permanent-magnet-synchronous motor (PMSM) (standard/nonlinear)
  • 3-Phase controller for PMSM, BLDC, SCIM

Power Electronics

  • 3-Phase discontinuous conduction mode (DCM) inverter and rectifier
  • 3-Level (3-Phase) inverter


  • ​​​​​​​Hall sensor

Benefits of the Motor Model

ASM Motor is complete: plant models together with control models let you setup a simulation, even if some parts of your software are still under development. The models support real-time simulation in fast timer tasks or hardware interrupt tasks like those necessary for PWM (pulse-width modulation)-synchronous model calculation, with extremely short sample times between 10 µs and 50 µs, depending on the real-time hardware. ASM Motor can be performed on software-in-the-loop (SIL) or hardware-in-the-loop (HIL) platforms, thus supporting continuous development and testing. Last but not least: the models are validated in various industry projects.


Features at a Glance 

  • Simulating electric drive components and power electronics in a closed loop with an ECU
  • Testing real or virtual machine controllers in a HIL or SIL system
  • Used in conjunction with 3-phase PWM measurement I/O
  • PWM-synchronous model calculation
  • Different internal discrete integration methods (Forward and Backward Euler, Tustin and mixed methods)
  • Compatible with automotive electrical system models

Scalable Simulations 

Depending on the requirements of the application, simulations can scale from:

  • Just a motor, without a specific controller
  • Accurate 3-phase motor simulation including current and torque profiles for controller development and testing
  • High-fidelity motor simulation on FPGA (field programmable gate array) platforms to emulate current ripples and other high-frequency effects

The models are easy to interchange because their interfaces are the same. This means consistency thus efficiency in development.
