In recent years, there has been an increasing demand for the design of complex motor drive systems, such as motors with more multiple motors and higher efficiency. MATLAB / Simulink and JMAG-RT are used as effective tools to address these needs, and model-based development utilizing simulation is becoming essential in motor development. We will introduce cutting-edge applications and results related to research and development of motor control using these tools.

Factors causing vibration in PMSM and methods to suppress them are important for low-vibration and low-noise drive motors for EVs as further value-adding in addition to smaller size, higher output, and higher efficiency. Focusing on vibration in particular, this lecture explains the factors that cause vibration due to motor electromagnetism and describes methods to reduce vibration by means of harmonic generation techniques. The presentation will include experimental results on methods suitable for three-phase motors, methods suitable for poly-phase motors, and the vibration suppression effects of case changes.

Multiphasing and control of induction motor drives are attracting attention to motor drives with more than three phases from various perspectives, such as high output, high voltage, high current, or fault tolerance. However, a certain cost increase due to an increase in the number of components is inevitable, and the introduction of such a system is expected to add value commensurate with the cost increase. From the viewpoint of control, this paper introduces a multiphase induction motor control system and pole number switching control, one of the added values made possible by multiphasing, using an induction motor, which is increasingly being applied to EV drives, as an example.

High-precision motor models for arbitrary circuit topologies have recently attracted attention for motors with three-phase double windings and open windings, aiming at further increasing motor output and downsizing the entire motor system including motor and inverter. wiring method and invar for a single motor. six-phase This presentation will introduce examples of analysis using JMAG-RT models for the 6-phase type and the newly added open-winding type.

The latest thermal management technology utilizing KULI is being used in Europe, where the electrification of off-highway vehicles for construction/agricultural equipment is rapidly advancing in Europe. In addition, its introduction by rental companies is expanding in Japan as well. This presentation will introduce the latest technology and its effects of Magna ECS and KULI users who have experience in electrification of construction machinery in Europe. The latest technology and its effect will be explained.

RCP, which greatly improves the efficiency of control system development, is required to improve efficiency through model-based development as control systems become more complex, including automated driving and electrification of automobiles. In this presentation, we will present RCP that can implement high-speed feedback control with no code and a high-performance HILS system that can also be used in the power electronics domain. The latest application examples and RCP and next generation motor HILS with machine learning models currently under development will also be presented.
