Analog Devices Acquires Test Motors, Adds to Condition-Based Monitoring Portfolio

November 4, 2019 Brandon Lewis

Analog Devices has acquired Test Motors, a Spanish predictive maintenance company. Test Motors specializes in detecting faults in electric motors and generators, and advises how they can be repaired before damage occurs.

The Test Motors acquisition follows ADI’s 2018 acquisition of OtoSense, whose AI sensing interpretation software used sound and vibration for early-stage detection of potential faults in machinery or engines. ADI intends to combine the two offerings into its condition-based monitoring offerings to provide more holistic analysis of machine health.

Test Motors will fold into ADI’s Automation and Energy Group. Terms of the acquisition were not disclosed.
