System Configuration Diagram
S1 Bench (High-precision measurement specification) ~High-speed dynamo+battery simulator~
Intermediate bearing-less, 20,000 rpm test.
The operating range may be limited depending on the weight of the EUT* motor and the directly connected structure.
*EUT: Equipment Under Test
S2 Bench (Large-capacity specification) ~High-speed dynamo+battery simulator~
The only one in Japan to achieve 20,000 rpm 400kW 700Nm specifications.
The operating range may be limited depending on the weight of the EUT* motor and the directly connected structure.
*EUT: Equipment Under Test
