Daikin Industries Ltd together with Osaka Metropolitan University, earned the 18th Electrical Technology Award “One Step on Electro-Technology” from the Institute of Electrical Engineers of Japan. Daikin Industries received recognition through the 18th Electrical Technology Award “One Step on Electro-Technology” because they developed a rare earth magnet motor with reluctance torque that improved air conditioner efficiency and reduced power usage. The celebratory event for the awards took place on March 19 during the year 2025.
Established within the 120th-anniversary celebrations of the Institute stood the “One Step on Electro-Technology” award to recognize pioneering electrical engineering achievements that benefit public welfare. Since 1996, when Daikin launched its breakthrough motor technology in residential air conditioners, the company has expanded this innovation to commercial us,e and it has fundamentally advanced energy efficiency standards in air conditioning systems. This groundbreaking innovation created new pathways for equivalent applications that propelled into industrial equipment hybrid electric vehicles (HEVs) and electric vehicles (EVs).
Air Conditioning Received A Breakthrough Innovation That Enhances Energy Efficiency In Industry Applications.
An air conditioning system requires various motor types for operational efficiency because it needs compressor motors to circulate refrigerants and fan motors to distribute the air. The award-winning interior permanent magnet (IPM) motor developed by Daikin achieves efficient energy utilization by placing rare earth magnets inside the rotor and performing shape optimization on the iron core and enhancing magnetic reluctance. The new magnetic force design strengthens the magnetic field and improves torque strength and lowers power use when compared to typical surface permanent magnet (SPM) motors.
The IPM motor technology from Daikin operates with inverter-based control to adjust motor speed carefully which enhances energy efficiency without affecting air comfort levels. The air conditioning motor starts its operation by quickly increasing speed until the set temperature is reached. The system establishes equilibrium at the lower operating speeds when the target temperature has been achieved while requiring minimum power consumption. An air conditioner operates steadily throughout most of its usage time so the efficient motor operation substantially decreases yearly power consumption.
The combined projection from The Future of Cooling report by the International Energy Agency demonstrates that worldwide air conditioner operation numbers will increase three-fold during the next twelve years. The 80% energy requirement of air conditioner compressors makes compressor motor efficiency improvement essential for reducing worldwide energy consumption.
Daikin’s Commitment to Sustainable Innovation
The company leads sustainable technology innovation by developing energy-efficient solutions which reduce environmental impact through continuous research.
