Menzel Motors: Electric motor maintenance and reconditioning

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.

Renewal of the winding of an electric motor

Working on the connection terminals of an electric motor

With our own turning shop, welding shop, winding shop, assembly facilities, and paint shop as well as one of the most up-to-date load test facilities, the machining possibilities at our motor factory are ideally and specifically tailored for the production and reconditioning of electrical machines.

We are able to retrofit and modernize motors in accordance with customer-specific specifications, the installation location, interfaces with other plants, and characteristic curves. Both the quality of the individual components and the quality of the reconditioning work are decisive with regard to the long-term functionality of a motor.

Due to many years of experience, MENZEL is not only able to overhaul any motor model or brand in the high-voltage, low-voltage, and direct current field; we can also replicate an existing motor.

We don't just overhaul old motors - we modernize them! A retrofit is the low-cost alternative to new construction. Older motors are brought up to the latest state of technology during a retrofit. This is done by recalculating the active parts such as the rotor and stator, for example.

Through the installation of modern components, the functionality of an older motor can be significantly increased and secured for the long term. In addition, as a result of a retrofit, older motors can meet the high requirements of the new energy efficiency classes.

If, in the case of a plant failure, the procurement of a new electric motor might take several months, the overhaul of an in-stock motor by MENZEL is also a good alternative. We can modernize and increase the efficiency of an older large drive really quickly by means of a retrofit, thus offering an appropriate long-term and cost-effective replacement for the customer's old motor.

During an overhaul or the reconditioning of drives, we are able to make custom adjustments, conversions, and modifications for you at any time. These measures include, for example, the adjustment of the axle shaft center height, shaft, base dimensions, or terminal boxes. MENZEL's engineers can attach external fans or modify the IP protection class or IC cooling method of an electric motor in a flash. If required, devices for speed monitoring (tachometer, incremental encoder), temperature monitoring (PTC/PT100), or vibration monitoring (SPM) can be installed. The final painting of the motor can also be adjusted in line with your wishes. MENZEL is your specialist for individual drive solutions!
