Evaluating Inverter Motor・Efficiency and Loss

Simultaneously measure inverter input and output power, and motor output.
Evaluate inverter, motor, and overall system efficiency and loss in an accurate and highly reproducible manner.

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.
