Organized Session

Organized Session 1

The session "Rotating Machines for Traction and Propulsion Applications" highlights recent advancements in electric vehicles (EVs) and aircraft electrification.

In the first presentation, Nissan introduces four key initiatives to reduce dependence on rare-earth materials in EV motors: heavy rare-earth reduction, magnet recycling, rare-earth-free magnet development, and the creation of an Externally Excited Synchronous Motor (EESM).

The second presentation discusses the development of a high-speed, lightweight motor prototype aimed at miniaturization and enhanced power density. This prototype achieves a maximum rotational speed of 34,000 rpm, reducing motor weight by 54% and doubling power density compared to traditional 50 kW-class motors.

In the third presentation, a novel motor drive system is proposed to streamline EV design by integrating both AC and DC charging functions, which reduces part count and improves overall efficiency. This system shows promising results in tests, with a 99.5% power factor for AC charging and doubled output voltage for DC charging.

The fourth presentation focuses on a direct-drive in-wheel motor utilizing a Halbach magnet array, which enables high torque at lower speeds and increases interior space efficiency. This system effectively cools the motor without a notable increase in fluid friction.
The fifth presentation showcases a hybrid electric motor designed for aircraft, aimed at MW-class output. The prototype demonstrates a maximum output of 365 kW in tests, showing potential for MW-scale propulsion systems in aviation.

Together, these advancements contribute significantly to the development of sustainable, high-performance rotating machines for traction and propulsion applications.

Organized Session 2

As electrification progresses in fields such as automobiles and aircraft, there is a need for smaller and lighter motor drive systems. Increasing the speed of the motor is effective in reducing the size of the motor drive system. However, there are many challenges specific to high-speed motors, such as mechanical strength, efficiency, and computation time. Therefore, in this special session, we will propose motor design and drive systems compatible with high-speed motor drive systems.

Organized Session 3

Currently, variable speed drive technology for AC motors is widely used in home appliances, industry, and transportation. Furthermore, recent motor drives are required to realize multiple technical requirements, such as high efficiency under multiple conditions. For example, motor drives that achieve both current harmonic regulation (IEC61000-3-2) and low cost, high efficiency, and high reliability, and both low-speed high-torque and high-speed low-torque regions. In this special session, we will propose power conversion technologies to meet multiple technical requirements for AC motors.

Special Sessions

Special Session 1

A magnetic bearing is a mechanical element which supports a rotating shaft without any mechanical contact by magnetic force. A bearingless motor is defined as a rotating machine that combines magnetically integrated bearing function. Due to non-contact operation, these are applied to ultra-high speed and contamination-free drives, such as turbo-molecular pump, turbo-compressor, ventricular assist devices, semiconductor manufacturing devices. This session focuses on recent technologies and related topics of magnetic bearings and bearingless motors.

Special Session 2

In order to reduce copper loss in rotating machines, a motor (Magnet Reversal Motor) that is driven by pulse current instead of sinusoidal current drive is introduced in this session. MRM is realized by a Flux Switching Motor, which is equipped with a variable magnet and is driven by changing the polarity of the magnet by a high pulse current. In this session, the structure and characteristics of MRM and its driving method such as main circuit, inverter module, and gate drive circuit with over current protection will be presented.
