Latest Patents

Baojiang Li holds a patent for an electric-machine housing. This invention effectively solves the technical problem in the prior art that electric machines have high NVH levels. The electric-machine housing is designed with a plurality of axial tunnels that can either be empty or filled with a damping medium. This unique structure weakens the excitation to the electric-machine housing caused by stator vibration. It increases the damping coefficient, reduces the transfer paths of vibration and noise, and ultimately lowers the amplitude of electromagnetic force waves. As a result, this innovation significantly inhibits vibration and noise, effectively reducing the overall NVH level.
