Our Challenge

Taking the Challenge in Creating New Business Markets by Using Technology as a Driving Force.

Development and Sales of Motors for Solar Cars and Eco-Run Races


The “Tokai Challenger” races at the Bridgestone World Solar Challenge

Using the world’s top level motor and control technologies, we strive to create new business markets. Our motors and controllers for solar cars and Eco-Run races are highly acclaimed both in Japan and overseas. In national races, over 98% of the participating teams use Mitsuba motors and such teams dominate the podiums.
Additionally, Mitsuba’s driving motors and controllers were installed on the Tokai University Solar Car Team vehicles that won consecutive victories at the 2011 World Solar Challenge and the 2012 Sasol Solar Challenge in South Africa.

Driving motor and controller used in the vehicle are created by the SCR Project.

Participation in EV Eco-Run Races


“Yoishotto! Mitsuba” earned the grand champion title, marking its seventh win at EV Eco-Run races.

A challenge to new technology: With this goal, our team of volunteering employees [Yoishotto! Mitsuba] continues to participate in various Eco-Run races. As a top team with a string of brilliant results, [Yoishotto! Mitsuba] won the grand champion title at the World Econo Move Grand Prix (WEM-GP), marking its seventh victory overall.

Development and Provision of Motors for Small Electric Vehicles

「μ–TT2」「MAYU」
Prototype vehicles “µ-TT2” and “MAYU” developed by Next generation EV Society, Gunma University

Mitsuba is a member of the “Next generation EV Society, Gunma University,” a collaborative effort between industry, government, and academia. Within this society, Mitsuba is engaged in the development of driving motors and controllers for the “µ-TT2” micro EV (one-person electric car) and the “MAYU” E-minibus (eight-wheel drive, ten-passenger electric minibus).
The micro EV and E-minibus are showcased on weekends, holidays, and at special events in downtown Kiryu, Gunma Prefecture.

SR Motor & Controller for Driving Electric Vehicles

For the “Electric Racing Kart (ERK)” that you can enjoy racing in eco-friendly manner, Mitsuba has developed a magnetless SR motor and a dedicated controller. These products are now used in the new attraction that you can drive on the international racing track, Suzuka Circuit, where the F1 Japanese GP is held.
The new SR motor has an improved hill-climbing performance achieved by optimizing the magnetic circuit and its rotor shape. Besides, the controller is compact and lightweight by adopting our original motor drive system.
We have also developed a pseudo 4-speed transmission software that controls driving force to the level suitable for circuit driving. By using this, the drivers can feel the real shift changing even when driving the EV with no transmission gears.

Autonomous Drive Robot


Autonomous Drive Robot “Meito-kun”

We develop autonomous drive technology that avoids obstacles and follows a specified path, as well as autonomous-drive robots
which adopt a small omnidirectional drive unit for indoor personal mobility.
