Measuring Power Losses in Electric Motors and Inverters
Mitch Marks, Business Development – Electrification, HBK
 

One of the main drivers for improving battery life is minimizing losses in the power conversion. Power losses can have many sources, and it is often difficult to determine the exact source you need to identify. In this session, we will review the basic sources of losses in electric machines and how to measure them, including copper, mechanical and iron losses. This will include the accuracy of the measurement chain needed to trust these measurements. The topics covered include copper, iron, and mechanical losses, power loss measurement and measurement uncertainty.
