Vibracoustic introduces modular mounts for electric motors
NVH products supplier Vibracoustic has unveiled a modular thermoplastic elastomer (TPE) bushing and a polymer beam mount for electric motors in battery EVs.
The company says they reduce weight and simplify assembly while also meeting OEM requirements for stiffness and isolation performance. Their integration ranges from bushings to a more sophisticated beam mount.
The motor mount bracket’s TPE bushing has double isolation, with the entire part acting as a damper. The mount can be tailored to the desired stiffness by changing the part’s geometry. Vibracoustic says the use of TPE in NVH applications is a new alternative to natural rubber.
The polymer beam structure uses the same TPE bushings and double isolation technology. It provides weight savings of up to 25%, is smaller than comparable alternatives and simplifies assembly. It also has a TPE damper mass integrated into its construction.
