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.

THE SOLUTION
PM6000 - Multi Phase Power Analyzer
  • Up to 6 channels for simultaneous input and output measurements
  • Best accuracy and common mode rejection available at high frequencies
  • Tracks motor frequency from 1MHz without compromise on functions
  • A fully fitted PM6000 (with 6 channels) can be used for measuring a motor controller (3 phase input and 3 phase output) for efficiency testing.
  • The PM6000 can also make torque and speed measurements of motor using the VPAS software.
PM3000ACE-001 - Three Phase Power Analyzer
  • The classic solution for drive measurements
  • PWM motor drive mode provides dependable measurements at the touch of a button
  • Discrete Fourier transform for very accurate power harmonics
  • PWM motor drive mode as well as auxillary inputs for torque and speed measurements
