Motor - Import export

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.

Application Asynchronous motors drive piston compressors in the chemical industry.

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.

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.
