LLOYD DYNAMOWERKE GMBH - three-phase motors, synchronous generators, compact asynchronous motors & DC machines

Application 4+2 synchronous main generators per ship for cruise liners.

Application DC motor replaced the old tandem motor from 1908.

Application Synchronous motor drives the rolling mill as main drive.

From the project planning stage through to the end of their operating life we offer a range of concepts for economical and fault-free operation of your machines Target-oriented maintenance intervals to match the respective operating conditions Online and offline status monitoring Trend measurements relating to wear behaviour of the mechanical and electrical components Stocking spare parts for shorter downtimes Training for maintenance staff 24 hour service Company-oriented maintenance contracts Modernisation of the machine, controllers and protection equipment Environmentally compatible recyclingTesting of electrical machines and systems, type tests, system tests, heat run tests according to DIN standards Dynamic balancing or rotors Cleaning and oven drying of large machine parts such as stators or rotors VPI impregnation with rotating hardening process in drying oven VPI impregnation of transformers and large coils VPI or resin-rich coil production Manufacture of tooth-wound coils

The repair works are located at our site in Bremen. Through the utilisation of all the resources of our manufacturing operations our customers enjoy all the benefits of repairs, maintenance and reconditioning in accordance with the DIN IEC60034-23 standard. For work on explosion-proof machines we can provide all the certificates required for order fulfilment in full compliance with legal provisions. LDW has a certified expert and the legally binding permits ATEX, PTB KTE etc. required for a professional execution. All AEG documents from around 100 years of electrical engineering are available in their entirety within our company. This enables us to carry out repairs, supply spare parts or complete machines that are electrically and mechanically interchangeable. As part of this process we upgrade these procedures in step with the latest technological developments. The energy balance is thereby significantly improved on a regular basis.

Machines are only as reliably available as their spare and wear parts. We therefore offer a comprehensive range of all important services. Thanks to our extensive archive, we are in a position to offer spare parts and services even for older machines from LDW, AEG and Garbe-Lahmeyer. We only need the serial number of the old motor or generator to provide or manufacture the corresponding spare parts. We are happy to assist with any question you have concerning our spare parts services, tender preparation or on-time procurement and delivery. The quality specifications we have for new parts of course also apply to our spare partsDespite the high quality of our products, the service life of some components is essentially determined by operating and environmental conditions. To avoid costly downtimes it is essential to implement preventative measures. Stocking spare parts is one example of such a sensible measure.

It is increasingly important to make provisions and to keep one’s own machines in good condition. This reduces downtimes and prevents a decline in production. Our seamless diagnostics helps to ensure that machines run fault-free and enables advance planning of maintenance or repair work. The experts from LDW bring their equipment to the customer to inspect the machine on site. From partial discharge measurement through to vibration measurement – we clearly identify what technical state a machine is in. This allows downtimes to be planned ahead and ensures the efficient repair of the respective component.Diagnostics at our works in Bremen is even more effective, because we can directly consult an expert from the mechanical construction, electrical calculation or the R&D department for an assessment if necessary. The customers are provided with a comprehensive protocol after the measurements have been carried out. We then recommend the next steps for a repair or continued operation.

We offer our customers the leasing of our test bays for testing your machines and systems.The above-mentioned machines can also be coupled in sets of three so that even higher outputs are possible. At LDW we also have several DC machines with other speed ranges and lower outputs. We also have three-phase load machines with speed ranges from 750 to 3,000 1/min at an output range of 1,400 to 3,000 kW. Our largest measurement shaft has a torque of 5,000 Nm (accuracy class <1%). We usually verify the torque via a DC-machine. We have several DC machines with speed ranges of 100 to 6000 1/min in the test bay (depending on requirements) at an output range from 100 to 1,500 kWThe maximum torque of our largest measuring shaft is 5,000 Nm (accuracy class <1%), we usually verify the torque via a DC-machine. Depending on the specific needs we have several DC-machines with speed ranges from 100 to 6,000 rpm and outputs from 100 to 1,500 kW.
