The ever-increasing demand for compact, efficient, and high-performance traction drive system for transportation has accelerated the development of integrated electric dives. The system generally consolidates the motor and inverter into a single housing offers substantial benefit in terms of electrical performance, volume, and weight while improving cost and system efficiency. Despite the advantages, integration introduces a new set of challenges, especially for power electronic design and component selection. This article presents a deep dive into an internal stator mount, highly integrated electric drive architecture focusing on unique considerations and design trade-offs solely to improve power density of the electric drive system.
