Evaluating Inverter, and Motor Efficiency and Loss

Simultaneously measure inverter input and output power as well as motor output through multiple channels.
Precise analysis of simultaneously measured data allows to evaluate inverter, motor, and overall system efficiency and loss with highest accuracy and reproducibility.

Measurement example


Please prepare the torque sensor and rotary encoder separately.


Analyzing Waveforms at Motor Start

Reliably capture and analyze instantaneous waveforms at the start of motor operation.
