e-MotorChamber: EMC Assessment System for EV Motors

e-MotorChamber is an EMC assessment system compatible with international standard tests that accelerates the development of high-voltage EV motors, which are a must in this day and age.

With our proprietary technology, the rotation and torque are directly transmitted with a simple structure that connects the test sample and the dynamometer with just a single shaft.
