Wheel Hub Motors

Increasing Efficiency in E-mobility

Wheel hub motors have the potential to revolutionize electric mobility! By integrating the motor directly into the wheels, weight can be reduced, efficiency increased, and vehicle space optimized. However, this technology comes with new challenges: cable routing, mechanical stress, and durability must be precisely analyzed and optimized – and this is where IPS comes into play.

Why is IPS ideal for wheel hub motors?

• Optimized Cable&Hose Routing: IPS enables precise physics-based routing to identify critical bending points and space constraints early in the design process.
• Dynamic Excitation & Durability: Cables and hoses are continuously exposed to small and large amplitude movements due to road vibrations and steering angles. IPS accurately simulates these real-world conditions, helping to detect weak points and maximize service life.
• Mechanical Stress & Durability: Wheel hub motors face continuous vibrations, shocks, and temperature fluctuations – IPS helps analyze and and minimize critical stress factors for improved reliability.

IPS enables early validation of the entire design, reducing weight, maximizing lifespan, and cutting development costs.
