1. Introduction: The Shift in Electric Motor Design For over a century, the electric vehicle (EV) industry and industrial automation relied almost exclusively on Radial Flux Motors (RFM). In a radial flux design, magnetic flux travels radially outward across a cylindrical air gap between concentric rotor and stator elements. While reliable and mature, conventional radial

Electrification is changing cars fast. But the real shift is happening underneath, right at the chassis. For decades, we relied on mechanical linkages to keep cars stable. Today, those physical connections are giving way to software-defined, drive-by-wire active suspension systems. This is not just a minor upgrade. It is a major shift in how cars
Many automotive teams face a common roadblock during ISO 26262 audits. They define high-level Safety Goals (SG). They establish the Fault Tolerant Time Interval (FTTI). Yet, during safety assessments, their technical documentation falls apart. Why does this happen? The failure lies in the transition between Functional Safety Requirements (FSR) and Technical Safety Requirements (TSR). When
