Product Description

For the winding testers, Schleich, as one of the first manufacturers of testing devices, concentrated, like at the GLP3-2000, consistently, successfully and reliably on the integration of PCs into testers. With more than 20 years of experience, our engineers and technicians offer you a perfect test system with extensive software. Both, hardware and software are designed and produced by SCHLEICH. In order to be leading in the field of measuring technique, SCHLEICH is continuously innovating its products. This great number of innovations is setting a high standard for the technology of modern winding testers with Windows® control.

The system offers: a clear indication of the test process for the operator - extensive input and configuration features for the person that does the set-up. Quality assurance is of great importance, also. For this purpose, an extensive, excellent statistical analysis is integrated into the tester. And, most important, you are able to document the tested quality of your products with a great variety of protocol print-outs. Regarding the generation of networks with testers of the MTC family, the same features as for the GLP3-2000 apply.

The individual test methods necessary for the stator test can be selected from a great variety of test methods. Manual or automatic station / single or double test station – with or without test cover or test table – we have the perfect solution. 

Two or four winding connections (at devices up to 15KV) and one frame connection serve for contacting the stators or the coil(s). Between the connection leads, the test is performed manually, semi-automatically or fully-automatically. An internal matrix automatically switches over between the connection leads.

2 connection leads for testing a coil
3 connection leads if motor is in triangle or star (U, V, W)
3 connection leads if the motor is a single-phase motor
4 connection leads if the motor is with outward-leading star point (U, V, W + star point)
4 connection leads if the motor is a single-phase motor

The MTC2 is controlled by the integrated PC. This device is a very flexible solution for maintenance and service within your company. The control software is the software of our MTC3 testers with all features of a high-end tester. The software enables you to perform fully-automatic tests, semi-automatic tests and manual tests. Especially within the area of service and maintenance, a great number of tests are performed as single tests. Test objects are examined in order to find possible faults. For this purpose, the tester offers optimum operating features.

1. Fully-Automatic Test

The test program consists of a sequence of individual test steps and every test step consists of a test method (e.g. surge test), set values and tolerances. After starting the tester, the individual test steps are performed fully-automatically one after the other and without interruption. Every test step is evaluated automatically. At the end of the test, you receive a total result. Testers with 4 connections allow to switch over between the connections. This is a pre-condition for the automatic test process.

2. Semi-Automatic Test

The test program consists of a sequence of individual test steps and every test step consists of a test method (e.g. surge test), set values and tolerances. After starting the tester, the operator can select the test step that he wants to test. Then, for example, he contacts the lamellas of an armature with the test probes and starts the test. The tester shows the measured value in the bottom half of the screen in large characters. As soon as the operator activates a button, the measured values are automatically compared to the set values of the test step and then evaluated. Now, the operator can select another test step, etc. This can be repeated until you have results from all test steps. It is possible to test individual test steps several times. The complete test process can be cancelled and continued later. The semi-automatic test is based on a test program with a fixed test step sequence with set values and tolerances. However, this test step sequence can be performed by the operator in the desired order.

3. Manual Test

There is no test program as a reference. The operator can perform individual test methods (e.g. surge test or resistance test, etc.) and connect the test methods to any desired connection clamp of the test object. During the test, the measured values are displayed in well-readable digits. After the test has been completed, the measured value is transferred to a summary of all measured values. Thus the operator can perform individual tests the same way as if he had individual testing devices. The results are accumulated in a summary and can be stored or printed.

Storage

For storing it is also possible to enter the data of the type label. With the data of the type label it is possible to search for the results in the database and, for example, load them for printing. This gives you a perfect documentation system for your motors, armatures, etc. For the completion of your documentation, you can also enter and store comments and notes. The software offers ideal solutions for a better comparison of existing and new test results of the same test object. This will help you to estimate the lifetime of the motor.

The software was optimized for mechanical engineering and the maintenance of equipment. With the three individual operating modes, the tester can be operated optimally and in accordance with practical needs. Although the tester has an integrated PC, the operation does not necessarily require a keyboard or a mouse. Everything can easily be operated by hand.

The operation of the tester is supported by the touch panel. The mouse can be controlled by touching the screen with the finger. This way, you can easily activate tests, reconnect clamps, etc.

Keyboard and mouse are only necessary if you you wish, for example, to store test results under a certain name - i.e. if you need to enter a text. The delivery extent comprises a keyboard and an optical mouse with radio connection and USB stick. Alternatively, it is, of course, also possible to enter the data without the keyboard via the touch panel.

We offer extensive extensions like test leads, armature adapters, lamella test probes, Kelvin clamps, test adapters, transport cases and equipment wagons.
