An EV Motor Assessment System Made Possible by Our Proprietary Technology
Achieves more than 20,000 rotations with a single long shaft
Feature 1: Long Shaft for High Speed Rotation
A dynamometer and a test motor are connected with just a single long shaft, enabling high-speed rotation of 20,000 rpm or more and high torque to be transmitted directly. It covers a wide range of specifications for EMC assessments of EV motors.
| Available standards | CISPR 25, ISO 11452-2, ISO 11452-4, GB/T 36282, automobile manufacturer standards |
Feature 2: We Offer Customized Solutions
The system can be customized to specifications to meet our customer’s specific requests. We also offer modifications to existing anechoic chambers. Please feel free to contact us should you have any questions regarding these services.

The maximum specs when customizing are as follow; Dynamometer achieves 20,000 rpm for rotation, torque for 350 N·m, 380 kW for capacity, while Battery simulator goes up to 1,000 DC for voltage, 600 A for current, and 500 kW for capacity.
MoreFeature 3: Implementation of Testing Service
EMC testing can actually be carried out in the demonstration anechoic chamber at the Fujimatsu Laboratory of e-OHTAMA (Kariya City, Aichi Prefecture).
*We have begun EMC testing using this system in September 2020.
