Comprehensive testing capabilities

Our range of static electric motor analyzers includes high-voltage and low-voltage testing in a single unit, giving you insights for a more complete motor health assessment. Motor insulation test options include surge testing to detect turn-to-turn insulation faults and partial discharge detection for early-stage insulation breakdown. High-voltage tests such as insulation resistance, step voltage and DC hipot and low-voltage tests such as winding resistance, impedance, capacitance and inductance are supported by automated and programmable test sequences for efficiency and repeatability.

User-friendly analyzers built to last

Why settle for older, proprietary interfaces that lack modern touchscreen displays and cloud capabilities? Our newer ADX models use an Android-based interface with Wi-Fi and Bluetooth® for remote access and simplified data sharing. Our durable, versatile analyzers are built for industrial environments and are renowned for their rugged construction, designed to withstand harsh conditions. With portable options allowing convenient transportation, we make safe testing easier.

Rely on the experts

Trust in our long-standing reputation for high-quality electrical test equipment to achieve your reliability goals – we've been sharing our knowledge for over 130 years. We've developed our static electric motor analyzers using our expertise in both motor testing and insulation diagnostics, so there's no need to compromise with our all-in-one solutions. If predictive maintenance, higher voltage capability, and modern connectivity are on your wish list, Megger’s electric motor testing equipment can take your testing to the next level.

Best in class for static motor testing

Our products offer the widest range of tests for reliability, including insulation resistance, surge, partial discharge (PD), winding resistance, inductance, capacitance and more. Many competitor products don’t provide surge and PD testing, which are critical for detecting early-stage faults. Megger’s standard models test up to 15kV, which can be extended to 40kV with the PPX power pack. With options for automated and programmable testing, combined with modern connectivity and data management, our electric motor testing equipment can give you the edge with deeper insights, whether for industrial maintenance, motor repair and rewinding or OEM and quality control.

Frequently asked questions

How do I use Megger products to test a motor?

We can explain how to test a motor as a simple step-by-step process as follows:

Essential for safety: de-energise the motor and lock out/tag out (LOTO) to prevent accidental startup. Discharge the capacitors and disconnect the motor from the circuit.
Select the correct test voltage, following the motor manufacturer’s recommendations.
Connect the Megger tester – the positive (red) lead connects to the motor winding terminal, and the negative (black) lead connects to the motor frame (ground).
Perform the Insulation Resistance Test by setting the Megger to the correct voltage and pressing the test button.
Interpret the results on the display screen – a sudden drop in resistance indicates degraded insulation.

You may also need to use tests such as Polarisation Index (PI) or Step Voltage Test for fuller insights.

When should I test a motor?

There are a few key times when it’s especially important to use our electric motor testing equipment:

During routine maintenance to prevent unexpected failures
After repairs or rewinding to check insulation integrity (use our analysers’ inbuilt motor winding tester)
Before installing a new motor, so you can be sure there are no manufacturing defects
After exposure to moisture or contamination to assess any insulation damage
