Product category: Electrical equipment
Our synchronous and asynchronous machines are distinguished by their high energy efficiency. The motors are reliable, safe to operate and robust. With our three-phase motors we offer special machines for almost any application. They are designed and built for the specific requirements of the respective drive application. We offer individually adapted motors – both in terms of electrical layout and mechanical design. We provide made-to-measure units, for example, for existing foundations or special bearings to absorb additional forces. The power network conditions on site are taken into account for the electrical layout to ensure that only minor voltage drops occur and a reliable run-up is guaranteed. Our portfolio comprises asynchronous motors with cage or slip-ring rotors as well as synchronous motors with brushless or static excitation.
LDW is a leading competence centre for DC machines. Our expertise has developed and been proven over many decades. As one of the few globally active manufacturers, we are able to replace machines from other providers with one from LDW – taking into consideration electrical and mechanical specifications and adapting them to customer-specific applications. The machines are individually adapted to the respective application. Our spectrum ranges from small DC machines to very large products. All machines are manufactured individually according to the requirements of our customers.
Continuous research and development has in recent years led to great improvements with regard to space utilisation and maintenance requirements of DC machines. In addition, the thermal and magnetic efficiency was increased and materials were optimised. The service life of brushes was significantly extended through this process.
Our compact asynchronous motors are distinguished by high torques in combination with a small size. They are highly dynamic with a low inertial moment, with a proven design as well as electromagnetically compatible for optimal, compact performance levels. We develop our compact asynchronous motors specially as speed-controlled drivers and for a supply from frequency converters. They also consist of a flexible platform system and can be adapted to specific customer requirements. The housing is angular and jacketless. Being ventilated by a separately driven fan, the motors can constantly deliver the full torque over the entire speed range. The optimised control behaviour with converter operation means that these machines can replace DC machines.
More than 100 years of experience and passion, combined in a manufacturing operation that uses the most up-to-date engineering craftsmanship and innovation – thats LDW. We supply reliable machines to meet the individual requirements of our customers. At LDW, we produce complex, high quality, hand-made three-phase motors, synchronous generators, compact asynchronous motors and DC machines, using modern technology. Our machines signify stability and character. They offer impressively high operational safety, long service life and reliability – simply premium quality “Made in Germany”.
Each of the countless manual operations required to construct the machines is handled by our 130 or so employees. Our team is experienced and ready to perform and create solutions. We are simply passionate about what we do and are so capable of – building reliable machinery! The challenge of developing the optimal solution for every need and always delivering the best quality while doing so is what distinguishes our working method. Our ambitious solutions are based on continual research and development. We work with various academic institutions to develop the optimal solution for any project. All under one roof: At LDW the entire life cycle process of a machine is supervised – from development and construction, to production and commissioning, plus ongoing support through the provision of spare parts and regular revisions.
As an SME, the pathways through LDW are short. We carry out the entire design and production process for the machines at our headquarters in the Hanseatic city of Bremen. We offer our customers individual, personalised support. We also aim to guarantee the same contact all the time. Our customers benefit from the tight dovetailing of our team – especially through fast, reliable service.
LDW technical sales are active internationally and across the globe. One of the important pillars of our business is that we are there on site with our customers – before, during and after the delivery of our products.
Since 2017 we are part of Powertrans S.A. from Luxembourg.
