This webinar will introduce a method for evaluating EV motor efficiency by separating electrical losses using the Hioki PW8001 power analyzer. Focusing on Permanent Magnet Synchronous Motors (PMSMs) under real operating conditions, the method analyzes copper and iron losses based on fundamental and harmonic power components. It reveals how increased inverter switching frequency leads to higher iron losses within the motor.

Join us to learn how, with wideband accuracy and User Defined Function (UDF) support, the PW8001 enables automated, real-time loss analysis. Efficiency and loss maps across torque-speed ranges support informed motor design decisions.
