Motor stator coil tester is a tester for quality testing of stator coils.

Ⅰ. Motor stator coil tester test items

There are two methods of winding motor stator coils: single wire winding and multiple wire winding. Therefore, the common faults in the manufacturing of motor stator are: wiring error, appearing error, coil wire diameter error, coil unit reverse embedded, surge error, poor insulation between phases, short circuit between phases, poor insulation between phases, short circuit between phases, poor insulation of winding to core, short circuit of winding to core, reverse embedded wiring and so on.

To cope with the above undesirable conditions, the motor stator coil tester has the following test items to choose from:

1. DC resistance: test the DC resistance value of each phase coil, which can determine whether the coil wire diameter is wrong, whether there is a serious short-circuit, broken wire, coil number of excessively poor, and other phenomena;

2. AC hi-pot: in the coil winding and iron core, between the specified value of the AC voltage, after a period of time, to check the AC dielectric strength, can test whether there is a short circuit, breakdown phenomenon.

3. Insulation resistance: Apply a certain DC voltage between the coil and the iron core to test the insulation resistance value to detect the coil on the iron core with or without leakage and short-circuit phenomenon;

4. Surge: between the windings to apply a certain amplitude and waveform of the impact voltage, can test the winding internal coil turns or between the phases of poor insulation or short-circuit phenomenon, and at the same time can be detected whether the number of turns of the coil is overdrawn, whether the coil unit is anti-embedded and wiring errors.

5 . Inductance

6. Reverse embedded wiring

7. Rotation

Ⅱ.Motor stator coil tester test process

Motor stator coil tester test process is relatively simple, according to the needs of the choice of vertical and desktop tester, according to the needs of the purchase can be.

The motor stator coil tester is a simple 3-step process to get the test results.

1. Connect the stator coil of the motor to be tested to the tester.

2. Press the start button or slide the slide cover on the tooling table to start the automatic test test;

3. The coil tester display shows the test result data and test curve, and the test is completed.

Ⅲ.Advantages of the motor stator coil tester

Ordinary coil test equipment testing capacity is limited, usually only detects the more obvious bad situations, and some of the more hidden winding embedded wire, local wiring error, and surge bad can not be directly identified, which will result in defective motor stator coil leakage inspection factory.

The motor stator coil tester developed and produced by AIP solves the above problems and has the following advantages:

1. The test is simple and comprehensive. Motor stator coil tester can test all the set items with one key, fast test speed, no need for manual operation for many times, reduce manual operation time, and improve test efficiency.

2. The tester applies to a wide range. The motor stator coil tester is suitable for all motor coil class stator testing.

3. An intelligent operating system. The tester supports intelligent self-test, remote troubleshooting, and online software upgrades without waiting, can be networked for system updates, and every time you turn the power on, the instrument is automatically detected to ensure that the normal daily test is performed.

4、Convenient test data storage. The tester supports network data storage, realizes data interaction and sharing, stores a large amount of data in the network without manual secondary input, convenient test data retrieval, saving time.

AIP specializes in global motor testing, with multiple types of motor stator coil testers to meet many motor stator testing needs. If you are interested in our motor testing equipment, please feel free to contact us.
