MotorAI is a company that has applied AI technology to the field of electric motors in an advanced way. At this exhibition, we will introduce various technologies, focusing on the “motor design agent” that autonomously designs motors while interacting with people. These technologies will contribute to the development of an electrified society by improving the efficiency and quality of motor design. At the booth, we will provide explanations of various technologies, including a demonstration of a conversation with an actual agent.

We will demonstrate our hardware-based parameter optimization technology. We optimize motor designs by integrating JMAG-Designer with Python. Similarly, we optimize motor control parameters using JMAG-RT models by integrating Python with Simulink. However, when differences exist between the model and the hardware, control parameters optimized on the model may not necessarily be optimal on the hardware. If control parameters could be determined on the hardware using the same algorithm as the optimization calculations performed on the model, the differences between the model and the hardware could be identified. Therefore, we have developed a hardware-based control parameter optimization technology using Python optimization calculations, similar to the control parameter optimization performed on the model. This allows the differences between the model results and the hardware results to be fed back into the model creation process.
As described above, our company handles motor design and analysis, motor prototyping, control simulation, and motor drive systems. We are also capable of handling drive circuit prototyping. Regardless of the exhibition content, if you have any motor-related concerns, please feel free to reach out.
