Discussion Topic: Power Failure Analysis and Efficiency Mapping for Electric Vehicle Motors within a Webinar Setting
The upcoming Virtual Conference on EV Engineering, broadcast live from September 15 to 18, 2025, will feature a webinar focusing on evaluating the efficiency of Electric Vehicle (EV) motors using the Hioki PW8001 power analyzer. This webinar, presented by Hioki USA, is a must-attend event for engineers and researchers interested in EV motor design and efficiency improvements.
The webinar, scheduled for September 17, 2025, at 1:15 pm EDT, will delve into the intricacies of motor and power electronics design, manufacturing, cell development, battery systems, testing, powertrains, thermal management, circuit protection, wire and cable, EMI/EMC, and more.
The Hioki PW8000 series power analyzers are renowned for their wideband accuracy and User Defined Function (UDF) support, and the PW8001 is no exception. This power analyzer aids in evaluating EV motor efficiency, especially for Permanent Magnet Synchronous Motors (PMSMs), by enabling real-time separation of electrical losses such as copper and iron losses under actual operating conditions.
The method, presented in the webinar, analyzes copper and iron losses based on fundamental and harmonic power components. It reveals the effects of increased inverter switching frequency, which leads to higher iron losses within the motor. The approach focuses on PMSMs under real operating conditions, providing more accurate insights for motor design and system efficiency improvements.
During the webinar, attendees will learn how to utilize the PW8001’s wideband accuracy and UDF support to automate loss analysis continuously during operation. Multi-channel power measurements will be captured to monitor motor electrical input and mechanical output simultaneously. The electrical losses will be separated into copper losses (due to winding resistance) and iron losses (due to core magnetization effects), based on detailed power component analysis.
Finally, the method maps motor efficiency and loss characteristics across torque-speed ranges to aid design optimization. This approach allows engineers to evaluate PMSMs in real operating conditions, rather than idealized or test-bench conditions, providing more accurate insights for motor design and system efficiency improvements.
Registration for the webinar is free, making it an invaluable opportunity for anyone interested in the field of EV engineering. Don't miss out on this chance to learn about the latest advancements in EV motor efficiency evaluation using the Hioki PW8001 power analyzer. The Virtual Conference on EV Engineering content will cover the entire EV engineering supply chain and ecosystem, making it an excellent resource for professionals in the field.
