Inverter Motor Efficiency & Loss Evaluation

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.
