BJM All-Test IV Motor Analyser

A versatile instrument the BJM ALL-TEST IV Motor Analyser works on all types and sizes of motors including induction, synchronous, servo and DC. Its sensitivity allows it to detect faults at their earliest stages, before motor failure and will detect “deep” winding faults that even a surge test will miss. Operation is menu driven with on-screen prompts and most tests take only a minute and give a complete picture of motor health. Tests can be taken from the motor control center, through hundreds of meters of cable.  The companion software provides fault diagnosis plus trending of all data.

The BJM All-Test IV is an excellent handheld analytical instrument for detecting and trending potential winding faults in AC and DC motors, transformers (distribution and transmission), generators, alternators and other devices with windings. It can also be used for off-line rotor testing for issues such as eccentricity, broken/fractured rotor bars, and casting voids. The ATIV will test fractional horsepower motors to large synchronous machines with established and easy to understand test measurement rules.

Along with an insulation to ground test the BJM All-Test IV measures resistance (R), phase angle (Fi), current/frequency response (I/F), impedance (Z) and inductance (L). Up to 500 motor tests can be stored and the test results can be sent to the provided computer software via the PC interface. The software offers analysis, trending and reporting for single and three phase AC induction motors.
