Your global supplier for industrial motors


Electric motor test facility

The MENZEL electric motor test facility in Berlin offers the latest test engineering for manufacturer-independent motor checks up to 13.8 kV.

Our test facility is one of the most up-to-date test stations of its type. It can also be easily hired for external motor tests. At our Berlin location, we offer you extensive test services encompassing routine checks, type tests, and system checks - including for external customers and brands. Our equipment includes a 6 kV converter, rotary converters for all normal voltages from 3 to 13.8 kV, and load resistors for checking generators.

The main usage scenario is the check of three-phase asynchronous squirrel cage and slip ring motors by means of a load check and/or heating test. However, the testing of synchronous machines or transformers, converters, and motor systems is also possible. In short: The technical possibilities of our test facility enable the realization of any type of special requirement.

An electric motor test facility that meets the highest demands

The MENZEL load test facility is the second test facility at the Berlin location. It was set up in our specially converted test hall in 2013. Here, a team of experts carries out tests up to 1,800 kW under load and up to 10,000 kW with no load - in accordance with the latest state of technology. In order to further expand our test service, we will shortly be installing another clamping field. This will allow us to ensure a smoother test process and to use the capacities of the test facility optimally to the benefit of our customers.

All measurements and tests are carried out and documented in accordance with the EN 60034 standards. However, our test facility engineers and technicians also have extensive experience and expertise with the test requirements of various inspection bodies at home and abroad. Our test facility also meets all technical prerequisites for validating internationally required quality standards and parameters.

See the function and performance of our electric motors for yourself! If you want, you can even be present during the check of your motors. For this purpose, an appropriately sound-protected and heated visitor cabin has been integrated into the MENZEL test facility. From here, you can witness all of the details of the test process.

Routine testing and type tests for all motor makes

As a group-independent medium-sized company, we carry out routine testing and type tests on all makes of three-phase machines for you - with the utmost care and quality. This means that our test facility is not only used for the routine testing of our company's own motors. Instead, it is available for you in the form of our test service offering, and you can hire it out!

Throughout Germany, only a few group-independent providers offer test services of this kind. The possibility of carrying out routine testing and type tests for all motor makes at our test facility - including electric motors that were not purchased from MENZEL - will make you more flexible in the future. Now, you are able to plan better, and no longer need to wait for ages for a test date. So don't delay - Arrange your motor tests with us today!
