MotorAnalyzer3

Beschreibung

The universal tool.

The universal MotorAnalyzer3 is used to test electric motors and winding goods. It combines 14 different test methods in a single user-friendly and mobile device. The combination of test methods, its extremely compact design and the battery operation option make the MotorAnalyzer3 an ideal tool for on-site use – even in difficult installation situations.

To test a three-phase motor, the three winding connections and the motor housing are connected to the tester. For highly accurate resistance measurement, this should be done using the four-wire method. The MotorAnalyzer3 then automatically starts the surge voltage, resistance, inductance and high voltage tests one after the other. To do this, the various test methods are automatically switched in sequence to the four measuring points via the internal relay matrix.

In addition to the motor test, the MotorAnalyzer3 also provides assistance in adjusting the brush rocker for DC motors and for locating faults in the two slots in which the coil with the turn-to-turn fault is located.

The MotorAnalyzer3 is housed in a very compact, robust and waterproof case. In addition to the generously designed display it features a storage compartment for all measuring cables and test probes. This means that the operator always has all the necessary components quickly at hand when taking measurements on site.
