                • Rotating converter sets

                • Rotating frequency converters or machine units
                  MENZEL produces tailor-made rotating motor-generator machine units for your test area.

                  The motors or generators of MENZEL rotating converter units consist of asynchronous or synchronous machines, or a combination of both. Unlike transformers, rotating converters can convert voltage and frequency (50/50 Hz, 50/60 Hz or 60/60 Hz) by combining machines with different pole counts.

                  Electric motors and generators are not magnetic, and are only coupled mechanically. This means that there is no direct electrical network connection in rotating converters. Instead, the energy is transmitted from the electric motor to the generator as mechanical energy, by means of a rotating shaft. The frequency converter enables supply isolation and effective filtration.

                  Power and voltage ranges of our rotating converter units
                  • Power: up to approx. 5 MVA
                  • Voltage: up to 11,000 V
                  • Rotation speed: up to 3,600 min-1
                  • Protection classes: IP20 to IP55 Coolant: Air or water

                  Rotating frequency converter – advantages
                  MENZEL rotating converter units are used for network disconnection. A particular advantage is the (almost) perfect sinusoidal shape of the voltage and current. This enables, for example, reference measurements on frequency-controlled motors and transformers without the additional losses that result from the harmonic waves of electronic frequency converters.

                  Voltage and frequency can be adjusted independently of one another across the entire operating range. Other advantages of rotating converters are the substantial overload capacity and short-circuit resistance, which are important for the test area.

Does your replacement motor need to act as a potential substitute for three different motors with different dimensions? Do you want to have the protection class or cooling method of a motor adjusted? No problem! As a manufacturer, we specialize in tailored custom constructions of electric motors in different power and voltage ranges.

                  • Replicas and replacements of electric motors
                    MENZEL Elektromotoren can replicate existing drives of all motor types and power classes identically - from a 100 kW crane motor to a mill drive in the megawatt range.

                    The replication of electric motors that are no longer available today is one of the tailored drive solutions of MENZEL Elektromotoren. Frequently, a certain electric motor is produced for a specific application. If this motor needs to be replaced, a practically identical motor is required. We can precisely replicate your electric motor so that the new motor is 100% suited to your plant.

                    If you are looking for no more available three-phase asynchronous motors from manufacturers such as Siemens or ABB, we can replicate them at our modern and extensively equipped Berlin location.

                    Our engineering department is ideally prepared for the task of replacing existing motors with new replicas. The replication of an electric motor by MENZEL avoids high on-site conversion costs and long downtimes. In addition, there is no need to make changes to your production plants, which avoids the frequently significant consequences of such modifications.

                    Naturally, our replicas comply with all valid standards and regulations.

                    Power range for individual replicas of industrial motors
                    MENZEL offers a range of possibilities for custom replicas of industrial motors in the low-voltage, medium-voltage, high-voltage, and direct current ranges. We can individually replace practically any electric motor with a replica. A precise analysis of the situation and of your actual requirements enable us to select the best and most cost-effective variant for you.

                  • Overhauling and reconditioning

                  • 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.

                  • MENZEL motor windings
                    Windings are the heart of any industrial motor. We realize the most diverse of designs for our new machines.

                    The high-quality windings of our MENZEL three-phase asynchronous motors (low-voltage, medium-voltage, and high-voltage) and direct current motors are designed in accordance with the latest state of technology. Often, new windings are also used as part of the modification of motors in order to enable quick adjustments.

                    MENZEL motor windings have been developed for high mechanical stresses. For this reason, our industrial motors can also be used in the most difficult environments and for really hard work in mills, crushers, and power stations. In the motor winding shop, we use only the latest insulation materials and top-quality wires.

                    A motor winding shop for challenging new windings
                    At our motor winding rooms, we have PC-controlled winding machines, a whole range of wire thicknesses for small to large industrial motors, impregnation plants, and drying ovens that are also suitable for larger electric motors.

                    The new windings are thoroughly checked during the production phase. At the end of the production process, each MENZEL electric motor is subjected to an extensive test run in our load test facility. In this way, we ensure the quality of all of our high-voltage and low-voltage windings.
