The NSK transmission-equipped wheel hub motor has two separate electric motors combined by a transmission specially designed for this purpose. The transmission is composed of two planetary gear sets, which can achieve both high drive torque and ensure high speeds.

At the same time, the motor is so compact that it can fit into a 16-inch wheel.In addition, this transmission has a feature that enables smooth gear changing even during acceleration by controlling the speed and torque of the two motors.

Building on the knowledge it has gained from the prototype wheel hub motor it developed, NSK is aiming to commercialize wheel hub components such as a hub unit bearing with a built-in speed reducer, the one-way clutch unit, the miniature cage and roller bearing, and the anti-corrosion bearing.//NSK Europe
