Reconditioning of an electric motor

Reconditioning of electric motors - the cost-effective alternative

With the modernization and reconditioning of high-voltage, low-voltage, and direct current electric motors, MENZEL offers an alternative to a newly constructed motor.

If maintenance and repair are no longer sufficient and a newly constructed electric motor is too costly, MENZEL can provide a cost-effective alternative in the form of a high-quality reconditioned motor. The availability of your industrial plant can be quickly and flexibly secured for the long term with an overhauled motor. Through reconditioning older drives, we can also modernize them and improve their efficiency.

As a manufacturer of large electric motors for industrial applications, we're ideally placed to judge what's necessary during reconditioning. Thanks to many years of experience, our MENZEL technicians and engineers can precisely assess which components need to be replaced or reconditioned and which can be reused. This allows us to inject new life into old motors.

Naturally, you get the same full MENZEL guarantee service on all three-phase and direct current motors reconditioned by us. 

Fast and flexible reconditioning of electric motors

At our test bay - fitted with the latest measurement equipment - we can carry out all required motor tests before, during, and after the reconditioning process. Our test bay engineers can make precise diagnoses and ensure our high quality standards in the production and overhaul of three-phase and direct current drives.

A further plus point: All work steps that are needed for the reconditioning or overhaul of an electric motor including disassembly, cleaning, drying, balancing and so on are carried out in close proximity at our own motor factory in Berlin. This saves time and money. With extensive modern production facilities and a high vertical range of manufacture, we are able to carry out all required work steps quickly and flexibly. The economic efficiency of a motor overhaul is always at the forefront of our minds.
