Automotive engineering and related charging technology are being significantly changed by electric vehicles.
There are numerous new needs for engineering thermoplastics as a result of the combination of the E&E and automotive industries.
Hybrid Electric Vehicles (HEV) are built with different topologies and control schemes to meet different requirements.
The design of the drive train components no longer depends on many formulae to achieve the required performance of the vehicle.
The primary restriction now is fuel economy and pollution levels. Before deciding on the sizes of the drive train components, the automaker must also consider the regulations governing road transportation.
Many researchers and automakers have embraced the modelling and simulation-based design approach. For the vehicle’s desired performance, the sizes of the drive train components are tuned.
Global Hybrid vehicle inverter component PPS resin market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
NSK is presently working on a novel and affordable strategy to stop electrical degradation in the electric car drivetrains (EVs).
In contrast to pricey “hybrid” bearings that include ceramic insulating components, EV makers will save money thanks to a novel technique for creating a patented plastic over-moulding for deep groove ball bearings.
Due to factors like the presence of an inverter that often shifts between various phases, parasitic current can go through an EV motor in a variety of ways.
A number of bearing current flows, such as rotor ground bearing currents, circulating bearing currents, and EDM (electrical discharge machining) currents, can also be caused by particular types of electric motor architecture.
It was time for NSK to start working on a solution to this long-standing issue, so the company first evaluated the operating factors that contribute to electrical erosion, such as load, rotational speed, temperature, and lubricant viscosity; the state of the resulting lubrication (hydrodynamic, mixed, boundary); and electrical characteristics like resistance (material and capacitive).
A more affordable solution is urgently needed since the high-voltage architecture of EVs is set to switch from the 400V systems that currently predominate to 800V.
By 2030, the latter could control 50% of the market, which will further compound the problem and necessitate even greater bearing protection measures.
