Bridgestone Unveils New In-Wheel Motor System
Bridgestone Corporation has unveiled a more compact, lighter version of its revolutionary in-wheel motor system for electric vehicles (Version III). Bridgestone first released details of the in-wheel motor system in September 2003. Then, a more compact and lighter version (Version II) was designed in September 2004. Based on this technology, Bridgestone developed the latest version especially for small tyre sizes.
Installing the drive motors inside the wheels means each wheel can be controlled individually, which supports excellent handling. It also eliminates the need for the differential gear and drive shaft and therefore allows for unprecedented freedom when designing vehicles. Designers can allocate more space to the driver and passengers without increasing the overall size and weight of the vehicle.
