Measuring Dynamic Motor Characteristics

Record inverter output voltage and current, torque, and RPM from motor start to stop.
Calculate inver ter output power, motor power, and motor efficiency using waveform calculations.

Measurement Example

Calculate Inverter Output Power, Motor Power, and Motor Efficiency Using Waveform Calculations

Calculate motor power, motor efficiency, and inverter output power after measurement using high-speed waveform calculations and display the results using the instrument's X-Y display function. The ability to use the X-Y display for waveform calculation results as well as input signals from measurement units means you can perform a broad range of analyses. Additionally, X-Y analysis can be performed at user-specified areas of the recorded fluctuating waveform, since you can choose waveform areas for generating an X-Y display.
