Product Description

The MotorAnalyzer is ideally suited for applications either within production or for service at the premises of the customer. The battery-operated MotorAnalyzer can be used to test electric motors even under difficult circumstances (e.g. when hanging on a crane). Owing to the great number of test methods and modern software analysis, supported by an optimal graphics display, the operator is able to make a clear "go / no go" statement.

Surge Test

For the surge test, the MotorAnalyzer generates surge waves with low voltage. Through the automatic surge wave comparison of all three winding connections, it is possible to make statements regarding the equality of the windings. Turn-to-turn faults would lead to a strong asymmetry of the surge curves. The surge curves are evaluated either manually, graphically by the operator or automatically by our approved mathematical analysis, well-tried at our large testers. The analysis is extremely reliable and doesn’t require any special knowledge of the operator.

Resistance Test

The resistance test is performed with high test current either single-phase, two-phase or automatically three-phase. All following the motto: connect the motor to the tester - push the start button - view the results of all three resistances. If necessary, the resistances can also be evaluated automatically via a +-% input. It is also possible to perform the test in 4-wire configuration. This allows to test small resistances precisely, also.

Automatic Test Process
	During the "Automatic Test", the tester indicates the test result on the display in clear text. The MotorAnalyzer makes automatic analyses on the basis of the surge test and the resistance test at an electric motor.

HVDC + Insulaiton Resistance

For the high-voltage or insulation-resistance test and for testing the PI, the device generates a regulated and stable test voltage DC. This offers a very interesting alternative to the high-voltage test with AC for finding insulation faults (turn-to-turn short circuit or ground short circuit). Although the final high-voltage test in compliance with VDE cannot be replaced by this test method, it is possible to make clear statements about the quality of the winding system (e.g. at the premises of the customer). For the high-voltage test according to standards, we recommend to use our tester GLP1-e HV.

HVDC + Insulaiton Resistance

High voltage and insulation resistance can also be tested with the step-voltage method: the test voltage is automatically increased in up to 10 steps from 0V to the programmed value. This method serves for finding insulation faults that are limited to small areas. The high electric load of the weak point especially occurs in case of high voltages. A fault is an indicator for the reduction of the insulation resistance when high voltages are applied. The evaluation is supported by the graphical display of the insulation resistance within the resistance/time diagram.

HVDC + PI

The PI or the DAR is tested fully automatically. The PI is an indicator for the insulation on the basis of the time/resistance ratio. For the PI, the test voltage is connected to the test object for 10 minutes. This causes a polarization of the charge carriers in the insulation - i.e. an orientation of the charge carriers towards the field lines. If the charge carriers are still mobile, this can be measured at the beginning of the test via an additional polarization current. High currents with constant test voltages result in lower resistances. At the end of the test (after 10 minutes) all charge carriers should be polarized, so that the resistance increases. The better the mobility of the charge carriers in the insulation, the better is the insulation of the test object.  This is indicated by a high PI. The PI is therefore an indicator for the age of an electric machine. Storing the insulation resistance and the PI of a motor in regular intervals and comparing the measured values for months or years supplies the information, when a machine needs maintenance.

Turn-To-Turn Test

Via additional test probes, stators am armatures can also be tested with the "classic" test method. For this purpose, the stack of the test object is contacted with the test probe. After this, the measuring signal at this test point is stored. Now, the operator moves the test probe manually around test object. The highly sensitive MotorAnalyzer indicates the deviation from the reference signal stored before - graphically in the form of a bar and digitally.

Neutral Zone
	For adjusting the neutral zone at DC motors, the field and the armature (the carbon brushes) are connected to the MotorAnalyzer. Now the MotorAnalyzer graphically indicates the deviation from the neutral zone.

Sense of Rotation at the Stator and at the Motor

The sense of rotation of the stator can be tested by a Hall rotary field probe. In the test field, the motor is, for this purpose, connected to a low rotary field voltage. The Hall probe measures the rotary field and the MotorAnalyzer shows it on the display.  The sense of rotation of the motor can be tested by directly connecting the motor clamps U, V and W to the tester followed by turning the motor shaft. This is an optimum solution, because, for this test, the motor doesn’t need to be connected to voltage.

PE Test
	Both, the PE test and the insulation resistance test can be used for "testing repaired devices" according to VDE standards.

Measurement of number of turns combined with a resistance test

The number of turns on a coil can be detected with test tongs. The test tongs are clamped on the coil or partial coil to be tested. The number of turns will be indicated on the MotorAnalyzer. This test method serves, for example, for checking the number of turns in stators. It can be used to control a winding machine and the pull-in technique. It is checked, how many turns of one phase are in one slot and whether is number is correct.

The MotorAnalyzer combines 10 different test methods of great importance in one device.

The MotorAnalyzer is the ideal tool for electrical machine construction, maintenance, installation of large-scale systems at home and abroad and for service in-house or at the location of the customer.

Being battery-operated and weighing only 2.7kg, the MotorAnalyzer is very easy to handle and allows a flexible application.

Features

Feature	surge voltage
	The surge-voltage test serves for detecting turn-to-turn faults, wrong number of turns and connection errors. At three-phase stators, these are detected through the automatic coil comparison between the 3 phases.
Feature	surge voltage with reference stator
	It is possible to read in a reference stator, so that the phase comparison is done to the phases of reference. This is ideal for small-series production.
Feature	reistance test with high test current
	This allows to test also small resistances well.
Feature	reistance test in 4-wire configuration
	This allows to test also the smallest resistances reliably.
Feature	battery operation
	The battery operation allows testing at the location of the customer without mains connection. The battery is charged via a simple plug-in charger.
Feature	automatic storage of the setting values in the tester
	In order to avoid operating errors, the device boots with the parameters of the preceding test.
Feature	adjustment of all parameters via comfortable menu navigation
	The comfortable menus make sure that the operator can adjust all test parameters correctly.
Feature	electronic test time
	By ensuring that the test time is the same for every tested product, the electronic test time in the automatic mode enables constant test results.
Feature	display of test parameters and test results via LCD at the front panel
	The operator can monitor the test via an LCD at the front panel. After a test object has been tested, the result remains visible on the LCD, so that the operator can easily view the test result.
Feature	calibration solely via the software
	The complete calibration is performed via the software. It is not necessary to open the device. All setting values are stored intenally in the tester.
Feature	actual-value storage for the results in the tester
	The tester can store test results inside the tester until they are read out by a PC program at a later time.
Feature	PC software: PrintCom
	This software allows easy reading-in of test results, storage in an EXCEL® file and comfortable printing of self-generated test programs.
Feature	Updates via Internet
	If the software is developed further, the tester can directly be updated via the RS232 connection. This way, the tester will always be up to date.
