Multifunction motor-drive analysers

May 2019 Maintenance, Test & Measurement, Calibration

RS Components has announced the availability of two motor-drive analysers from test and measurement maker Fluke, which help to locate and troubleshoot typical problems on inverter type motor-drive systems.

The MDA-510 and MDA-550 help engineers save time by enabling the quick set-up of complex measurements, and the simplification of the troubleshooting process via guided tests and automated drive measurements. Users of these instruments can simply select a test, and then step-by-step guided measurements show users where to make voltage and current connections. Pre-set measurement profiles ensure the capture of data for each critical motor-drive section, including from input to output, on the DC bus, and the motor itself.

The MDA-510 guides users through this process of making measurements from the power inputs to the motor outputs of the drive, and offers specific information about different measurements and how to connect them, along with diagrams showing the connections. The MDA-550 adds to these capabilities by enabling the measurement of harmonics around the fundamental frequency as well as in the higher range from 9 kHz to 150 kHz.

It also includes shaft voltage measurement, probes and probe holders.

Offering four input channels for voltage and current signals, features include measurement of key motor-drive parameters including voltage, current, DC bus voltage level, AC ripple, voltage and current unbalance, and voltage modulation; as well as measurement of additional electrical parameters via a full 500 MHz bandwidth oscilloscope. Other features include quick and easy report creation, and USB A and USB mini-B connectivity.
