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.

Waveform analysis and power spectrum analysis of motor input

Voltage and current waveforms can be analyzed, as well as to perform a comprehensive analysis of active power on a frequency basis.
