In-Wheel Motor Systems — For More Controlled Ride

In-wheel motor systems are nothing but drive systems that use motors installed inside vehicle wheels. These motor systems are much better in performance and control than their predecessors. In year 2004, tire leader Bridgestone introduced a revolutionary new dynamic-damping system which improves the performance of electric vehicles. This technology uses the motor to offset vibration from the road and tires, which improves handling and comfort in electric vehicles. Bridgestone’s dynamic-damping system overcomes disadvantages of existing in-wheel motor system that has limited the applicability of those systems due to increased weight and less controlling power.

Undoubtedly, these new systems have helped realize the dream for many vehicle owners due to their rich features. Installing the drive motors inside the wheels allows for controlling each wheel individually (instead of axle or main shaft), which enhances overall handling and performance. The new technology also eliminates the need for a differential and drive shaft and allows for freedom in designing vehicles. The new technology also offers the designer the benefit of greater space on the vehicle body, which allows more space for driver and other passengers.

As compared to their predecessors where every thing was open to dust and water, now Bridgestone has increased its lead in in-wheel motor systems by reducing the size and weight of its system, by enlarging the range of motor movement, and by increasing the system's resistance to water and dust.
