Application Motor as drive for a compressor for support of oil production.Special cooler design to withstand even sandstorms in the desert.

Synchronous generators from LDW are highly versatile and are used in shipbuilding, power stations and many other applications. Our generators can be driven by gas, steam or water turbines as well as diesel engines and other drivers. Synchronous generators from LDW have a high degree of efficiency and operate with extreme effectiveness. We develop and manufacture generators of the highest quality standards.LDW supplies synchronous generators with an output range from 4,000 to 60,000 kVA.Our synchronous generators are specially optimised for the specific application of the customer, e.g. if used for water power turbines with regard to runaway speed and turbine force absorption. Where diesel generator sets are used, the vibration load in particular is taken into account. On request, we will also construct the generator with a forged-on flange. A high degree of efficiency is ensured for all generators.

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.

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
