[Editor's Note] With the increasing use of motors in various industrial sectors, including electric vehicles, UAM, and robotics, precise motor control solutions have become essential. Headquartered in Germany, MOTEON provides software solutions for high-performance motor control using Infineon's MOTIX™ products, improving the reliability and efficiency of motor control across industries. On October 31st, we met with Yong-gyu Cho, Director of the Technology Research Center at Dabo Corporation, who was introducing MOTEON's motor control software solutions, through the e4ds ee webinar. He discussed the topic of precise motor control.


■ As the use of motors in vehicles has increased recently, developers need development knowledge to precisely control the motors. Could you please introduce the knowledge or resources required for precise motor control?

As the use of motors in vehicles increases in recent years, the technological capabilities that allow developers to precisely control motors have become increasingly important.

The key knowledge and resources required for this can be broadly divided into three categories.

First is control theory and algorithms.

To control a motor precisely, an understanding of basic control theory such as PID control (proportional-integral-differential) is essential.

Furthermore, advanced algorithms such as nonlinear control and model predictive control may also be required depending on the operating characteristics of the motor.

These algorithms help monitor and adjust the motor's rotation speed, position, current, etc. in real time.

Second is understanding hardware and sensor technology.

Understanding the hardware is also important for building an accurate feedback system for motor control.

For example, position sensors such as encoders and current sensors are required, and the ability to process data from these sensors in real time is also essential.

Knowledge of electronic components, such as motor driver circuits, also contributes to maximizing motor performance.

Lastly, there are motor characteristics and software development capabilities.

Software development capabilities for motor control are also essential.

It is necessary to be able to write control programs that are suitable for the operating characteristics of various motors, such as DC motors, BLDC motors, and stepper motors, and to optimize software that operates on embedded systems such as real-time operating systems or microcontrollers.

In conclusion, to control the motor precisely To do this, it is necessary to comprehensively acquire control theory, hardware understanding, and software development capabilities.

These elements will ensure stable and efficient operation of the vehicle's motor, ultimately contributing to improved vehicle performance and safety.

■ Please introduce MOTEON motor control software.

Motor control software provided by MOTEON provides software solutions for high-performance motor control using Infineon's MOTIX products, improving the reliability and efficiency of motor control across industries.

For developers, these solutions can be a valuable resource for solving a variety of motor control problems.

The main features of MOTEON's motor control software are that it provides control solutions suitable for various electric motors such as BLDC (Brushless DC), PMSM (Permanent Magnet Synchronous Motor), and SRM (Switched Reluctance Motor), enabling precise speed control and torque control, real-time control and optimization, and providing highly reliable software because it was developed based on ASPICE required in automobiles, and it even provides a development environment where customers can monitor and control data related to motor operation in real time.

■ Motors control mechanical movement, but electronic control takes priority in driving the motor. It is very difficult for developers to fully understand these characteristics, so it is thought that SW will need to provide a lot of assistance during the development process. I wonder if MOTEON motor control software has features that can help developers alleviate these concerns.

Before developing motor control software, it is important to understand how much torque the motor can produce at the various speeds required by the application.

MOTEON motor analysis tool shows the limits, performance, and operating range of a motor.

The tool also includes MOTOR Analysis software that includes the ability to accurately visualize the potential range, taking into account external conditions such as system parameters such as voltage, operating mode, device temperature, and tolerances.

We also offer a compact test bench system designed to help developers debug and validate software and hardware for embedded motor control applications in a standardized and functionally safe environment, providing a development environment that can be quickly set up without compromising high safety standards, even in a workshop environment.

■ Please introduce the webinar to be held on October 31st.

This seminar will explain real-time data acquisition and motor control software development and verification using MOTEON's sensorless motor control software and analysis tools and PC-based hardware equipment, TraceBox.

We would like to ask for your interest and participation from those interested in motor control software in the automotive field.
