Repairs of electric machines / motors

We provide standard and non-typical repairs of motors and electrical systems and all related services.

Inspections, overhauls, rewinding, mechanical  repairs of:
–        high voltage cage and slip-ring motors,
–        low voltage cage and slip ring motors, single- and multispeed motors for various purposes,
–        direct current motors,
–        traction motors,
–        SCHARGE motors,
–        we use the insulation according to the classification from A to F,
–        provide renovation and replacement of shafts.

Modern drives, application of converters. We offer:

–        selection of a proper motor within a brand indicated by the customer
–        selection of adequate frequency converters – we can provide a wide range of converters in various prices (but with similar quality and properties)
–        execution of cable routes, cable laying, connection, measurements
–        assistance with the first start-up
–        information and operation trainings

What are we proud of?

We have already executed several dozens of such works for various investors. We have mounted converters of the capacity even above 1 MW.

Our work was assessed as a high quality performance. We do business with the best companies: ABB, DANFOSS, ELIN and many other. If you want to have modern drives, contact us and you will not regret it!
