Ebara buys Mitsubishi’s three-phase motors business
12 November 2025 
The Japanese pumps, blowers and compressors manufacturer Ebara is buying Mitsubishi Electric’s three-phase motors business for an undisclosed sum. Mitsubishi now plans to focus its resources on its factory automation business and its technologies such as PLCs, servodrives and CNC systems, with a view to strengthening and expanding these activities.
The assets being transferred to Ebara include:
- Mitsubishi’s three-phase and IPM (interior permanent magnet) motor businesses, together with production facilities at its Shinshiro Factory. The business has developed a proprietary motor technology that achieves IE5 efficiencies.
- The industrial motor, pump, and diecasting businesses operated by Mitsubishi Electric’s Thai subsidiary, Mitsubishi Electric Automation (Thailand).
The parties plan to complete the deal during 2026, subject to approvals by the relevant authorities.
Mitsubishi’s Shinshiro Factory also produces spindle motors and servomotors for CNC (computer numerical control) systems. These businesses are not part of the transfer to Ebara. Mitsubishi will continue to manufacture these products at Shinshiro in part of the site that it is keeping.
As well as the production facilities in Japan and Thailand, Ebara is also acquiring Mitsubishi’s development capabilities and technical know-how. It says the deal will accelerate its global growth and help it to achieve a decarbonised society by providing energy-saving technologies that combine motors with rotational control.
“Motors are essential core components for industrial machinery,” says Ebara executive officer, Shu Nagata, who is also president of its Building Service & Industrial business. “By leveraging this business transfer as an opportunity to integrate motors and industrial machinery, we will expand the deployment of high-value-added solutions, such as energy efficiency and predictive maintenance, going beyond product provision.
“We will inherit the technical expertise, customer base, and human resources that Mitsubishi Electric has accumulated over many years, fundamentally transforming our business structure through the technological fusion of research and development, and optimise our global supply chain management to integrate the resources of both companies,” he adds. “We aim to maximise the synergies created from this integration to drive business growth and further expand our presence in the global market.”
Mitsubishi executive officer Takayuki Tsuzuki, who is president of its Factory Automation Systems business, says: “Mitsubishi Electric’s three-phase motor business within the FA Systems division has built up nearly 100 years of technology and experience since production began in 1924. By transferring the advanced technologies to Ebara, we aim to contribute to the broader development of the three-phase motor market.
“Going forward, we will focus on growth in our digital solutions and core component businesses,” he continues. “In addition, by utilising our digital platform, Serendie, we will prioritise solutions that create new value as part of our transformation into an innovative company.”
