Solar car electric car, the sun's energy into electrical energy drive motor and steering tires.

 World Solar Challenge "is one of the largest solar car race in the world, participants race over 3021 km, through the Australian desert between Darwin and Adelaide, using the sun as the only power source. Has 20 years of history, Since 1987 began, the race attracts participants from around the world, including many universities and businesses. Institute's goal is to win in the game the first time on the podium.

     Solar car electric car, the sun's energy into electrical energy drive motor and steering tires. With minimal power dissipation structure design requires long-distance driving using only electric power obtained from solar cells. Deep groove ball backing bearings NTN challenges provided by the JIS 5 magnitude, which is higher than the general JIS 0 级 two levels to help improve machining accuracy. Ceramic balls has changed ball rolling contact surface curvature is optimized to reduce the contact area and achieve a lower torque, while stirring resistance with minimal low-viscosity grease has been used. This helps to reduce 50% of the torque compared to conventional products. Gangdun has been changed to non-contact rubber seals to improve driving through the desert to prepare to resist the penetration of foreign substances.

     In addition to wheel motors, NTN bearings used in the drive wheel shaft rotational torque reduction. This helps to achieve high speed with minimum power consumption, but also contribute to long-distance driving.
