The all-purpose MotorAnalyzer 2 is used for checking electric motors and windings. It combines 13 different test methods within a user-friendly and mobile tester. The combination of test methods,its compact design, as well as the battery operation, turn the MotorAnalyzer 2 into an ideal tool for on-site operation, especially in difficult applications.

For checking a 3-phase motor the three winding connections and the motor’s cabinet are connected to the tester. This testing is done with four wire technology, providing high precision resistance measurements. After the Kelvin resistance test, the MotorAnalyzer 2 performs fully automatic testing via surge test, resistance and inductance. The MotorAnalyzer 2 automatically switches between different tests via its internal relay matrix. Finally, a high voltage test is done to evaluate the motors quality.

In addition, the MotorAnalyzer 2 provides information on brush holders and turn-to-turn faults within DC motors.
