The world consumes approximately 45% of its electricity through electrical motors. As the trend for electrification grows, the efficiency of the motors becomes increasingly important.

In his doctoral dissertation, junior researcher Valerii Abramenko suggests that the Synchronous Reluctance Motor (SynRM) with Axially Laminated Anisotropic (ALA) rotor could be a game-changer in the world of electrical motors. This revolutionary motor has the potential to significantly increase efficiency while reducing energy consumption and emissions.

“Increasing the efficiency of every electrical motor in the world by just 0.1% could save enough energy in a year to charge over 209 million Tesla Model 3 or over 715 billion iPhone 14 Pro Max once. It could also reduce CO2 emissions by an amount equivalent to over 1.3 million conventional cars,” Abramenko states.

A promising solution for high-speed applications

In his research, Abramenko delved deep into the electromagnetic aspects of the motor, providing the best design practices for optimal performance. Additionally, several ALA rotors have been manufactured and measured, verifying the obtained findings.

“Unlike current high-speed applications dominated by induction motors and permanent magnetic synchronous motors, the SynRM with ALA rotor does not face so strict limitations in efficiency, thermal issues, or manufacturing concerns,” Abramenko says.

The research suggests that the SynRM with ALA rotor is an extremely promising solution for high-speed applications, opening up a new niche for further exploration and development in the field of high-speed technology. The rotor has a straightforward operating logic and potential to achieve high robustness of the rotor structure. In addition to the fact that high-speed technology itself needs less material than normal speed machines, the ALASynRM also doesn't require magnets.

“The innovative solutions like this can make a significant impact on the fight against global warming by reducing energy consumption and emissions. It’s exciting to think about the possibilities for the future of the motor industry.”
