Webinar Overview
A webinar hosted during the September Virtual Conference on EV Engineering, presented by Hioki USA, will explore a novel approach to evaluating the efficiency of electric vehicle (EV) motors. The session aims to address how electrical losses in Permanent Magnet Synchronous Motors (PMSMs) can be precisely analyzed in real operational conditions. Attendees will learn how to distinguish between copper and iron losses by analyzing fundamental and harmonic power components.
One insightful aspect of the method is its emphasis on the relationship between inverter switching frequency and the associated iron losses in motors. The discussion will highlight how higher switching frequencies can result in increased losses, providing critical information for motor design.
Participants will see demonstrations of the Hioki PW8001 power analyzer, notable for its wideband accuracy and support for User Defined Functions (UDF). The device enables automated and real-time loss analysis, facilitating the creation of efficiency and loss maps across various torque-speed ranges. This data equips engineers and designers with essential insights to make informed decisions about motor design.
This insightful session is scheduled for September 17, 2025, at 1:15 PM EDT. Attendance is free, and interested parties are encouraged to register to secure their place.
