A COMPLEX MEASUREMENT PROBLEM:
Thousands of design and test engineers trust Voltech power analyzers to provide
clear and definitive measurements on PWM (pulse width modulation) drives or VFD
( variable frequency drives) for AC motor or DC motor testing applications. Our
power analyzer range is ideal for motor and drive testing because the analyzers
are easy to use and provide accurate motor measurements such as motor efficiency,
motor inrush current and motor harmonics without complex setup.
Drive and motor systems present unique challenges for measurement instruments. The
unique DSP algorithms of Voltech power analyzers accurately resolve low frequency
information from the high frequency signals produced by PWM motor controllers to
provide the measurements you need at a touch of a button.
Whether you are interested in the drive, the motor or the total system efficiency,
only test instruments that are specifically designed for this demanding application
will provide meaningful results for electrical and mechanical power parameters.
Whether making AC measurements or DC measurements on PWM drives or VFD drives, measurements
must be made simultaneously at all stages of the drive.
