Motor drive analysers head to Birmingham show

The analysers provide complete three-phase power analysis from motor drive input through motor mechanical output, with results in a convenient Numeric table format. Motor speed, position, and torque integration are the most complete available.

Long memory, per-cycle “synthesised” Waveforms and Zoom+Gate mode provide powerful dynamic drive and motor analysis. 8 analog input channels with high resolution (12-bits), sample rate (up to 2.5GS/s), bandwidth (up to 1GHz) and memory (up to 250Mpt/ch) provide unique capability to perform complete system debug on the motor drive power section, motor mechanical performance, and embedded drive control system operation.

The MDA acquires drive power section, power transistor, and embedded control system signals, and performs three-phase power analysis of the power section waveforms.

Correlation of drive system behaviours to embedded control loop signals enables debug and analysis of all aspects of the complete motor drive.

Various voltage, current, power (real, apparent, and reactive), phase angle/ power factor, and efficiency parameters are calculated on acquired voltage and current waveforms and displayed in a

Users can capture long acquisitions and Zoom+Gate with instant table value updates and views of dynamic three-phase power and motor drive performance.

Simple integration is provided for nearly any type of speed, rotation or position sensor, including analog and digital (pulse) tachometers, Brushless DC (BLDC) Hall sensor, Quadrature Encoder Interface (QEI), and Resolvers.

Additionally, Hall sensor and QEI signals can be integrated through digital inputs, preserving valuable analogue input channels for other signals.
