Motor testing is performed on motors to diagnose what is causing them to run hot, fail to start, continuously trip their overcurrent device or function deficiently in some manner. Motor testers measure motors by assessing parameters like the three-phase power quality, speed, torque, and efficiency of the motor in order to determine faults. 

A portable motor analyzer delivers comprehensive, detailed test results and data commonly used by maintenance professionals in motor service/repair shops, industrial motor maintenance and OEM motor manufacturers.
