Propulsion e-motors - New technologies and supplier dynamics

Publication Date: 16/04/2021

As the world moves toward the elimination of fossil fuel dependence, the automotive industry is playing a critical role in contributing to the achievement of global air quality and emissions targets. Governments and regulatory bodies are mandating increasingly stringent emissions and air quality targets that automakers must achieve to sell vehicles.

In the aftermath of the Diesel Emissions Affair, automakers have come under increasingly tightening scrutiny to reduce carbon dioxide (CO2) emissions from their vehicles. This is subject to more demanding testing procedures such as the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) and the Real Driving Emissions (RDE) norms.

The growing magnitude of electrification in automotive powertrains and the emergence of battery electric vehicles (BEVs) are indicators of the direction that the vast majority of the industry looks set to follow.

Within the automotive industry, tier-1 players are offering integrated motor-driven electric drive units that either complement or replace internal combustion engine (ICE)–powered architectures.

Shifting consumer preferences toward four-wheel-drive crossover and sport utility vehicle (SUV) body styles also contribute significantly toward increasing electrified axle drive (e-axle) applications as OEMs look to mitigate weight and aerodynamic deficiencies.

This report aims to understand the fundamentals of e-motor technologies, the benefits of integrated e-axles, and the future market demand for electric propulsion motors.
