DC “asynchronous motor” as a replacement for DC motor with brushes

DC „Asynchronmotor“ als 1:1 Ersatz für konventionellen Gleichstrommotor mit „Bürsten“

As a specialist in the development and production of motor electronics, MSB Elektronik und Gerätebau has recently made a name for itself with the realization of an innovative project. The company developed a DC asynchronous motor as a direct replacement for conventional DC motors with brushes.

This step was aimed at improving the efficiency and ease of maintenance of oil pumps for the pre-lubrication of large generators. By adapting to specific customer requirements, not only was operational reliability increased, but maintenance costs were also significantly reduced, underlining the company’s technical expertise and commitment to customized solutions.

Induktive Abstandsmessung für Temperaturen bis 500°C

Inductive distance measurement for temperatures up to 500°C

The inductive distance measurement, designed for use in the demanding environments of power plants, is characterised by its high temperature resistance of up to 500°C. Thanks to a sophisticated, temperature-compensated measuring method, the system offers high reliability and is insensitive to environmental influences.

The recorded measured values correlate linearly with the measured distance and can be provided to the user both in the form of an analogue signal and in digital form. This flexible signal provision enables simple integration into existing systems and offers a wide range of possible applications.

Current-heating unit 1000 A

Current-heating unit 1000 A

The customised development of a DC-AC current transformer for “baking” motor windings is a demanding and specialised project.

This device is mainly used in the repair and manufacture of electric motors, in particular to harden the windings and extend their service life.

grid inverter 15 kVA

15 kVA grid inverter

The grid inverter feeds electricity into the public supply grid in accordance with VDE AR-N 4105 up to an output of 15 kVA. In combination with an integrable frequency converter for high-speed generators, the feed-in system represents a complete solution for the operation of ORC systems (Organic Rankine Cycle). It can be used with hot gas or micro gas turbines as well as high-speed flywheel mass storage systems.

Compressor with fully integrated frequency inverter for mobile use

Compressor with fully integrated frequency inverter for mobile use

Designed for mobile use, the frequency inverter is characterised by an innovative circuit design and advanced control algorithms, which have significantly increased the energy efficiency of the overall system – consisting of the frequency inverter and chiller.

A key feature of this system is its compact design. It only requires the space that was previously taken up by the chiller alone. This optimisation, not only in terms of efficiency but also in terms of space requirements, makes the system particularly suitable for applications where space and energy efficiency are crucial.
