The behavior of brushless DC motors can now be evaluated virtually, thanks to FAULHABER’s addition of these motors to a Simulink library. Without needing physical hardware, users can integrate these motors into simulated applications to predict how they will perform in real-world situations. This virtual approach simplifies the development process, allowing quick trials of different drive configurations with just a few clicks.
For example, a logistics transport drone requires highly responsive and precise drive control. The motors must react immediately and apply smooth, well-regulated force, making the demands on the drive system quite high. Simulating these systems beforehand saves time and reduces the risks associated with hardware trials.
FAULHABER is the first micromotor provider to offer this advanced simulation capability at an early development stage. Simulink, a widely used block diagram simulation software, allows users to test and adapt various solutions early in the design phase, ensuring real-world applicability. Marc Lux, FAULHABER’s application engineer, created a library containing all brushless DC motors, encoders, and motion controllers. Users can easily emulate the motor’s electrical and mechanical subsystems by modeling the system’s equations.
By incorporating typical sensor system influences, customers can simulate realistic speed characteristics and create customized controllers for brushless FAULHABER motors. This method cuts down on development time and minimizes risks, even though final physical tests are still necessary.
The Simulink library includes modules for torque, speed, and motion control, allowing users to simulate complete drive systems. Models like the MC 3001, MC 3603, and MC 5005 motion controllers can be used alongside motors and configurable load inertia to establish real positioning times and controller parameters.
To facilitate the process, Lux developed a Matlab toolbox that integrates various scripts, tables, and drive models into a user-friendly interface. Available online since early this year, FAULHABER’s Simulink library supplements existing tools like the FAULHABER Drive Calculator and can be used to create digital twins for advanced IoT and Industry 4.0 applications.
FAULHABER is a leader in developing and manufacturing high-precision miniature and miniaturized drive systems, offering over 25 million drive system combinations.
