Detailed information

The production era for electrical machines in Switzerland began in 1891,
when BBC (Brown Boveri & Cie) was founded. In 1963, the motor factory, which had grown over time, moved to Birr. In Birr, the scope of delivery covered a wide range of different electrical medium-voltage machines:

  • Synchronous & asynchronous AC motors and generators
  • DC motors
  • Slip ring rotors
  • Brushless DC and AC excitation systems

Our Company


New company formation

In 1988 ABB (Asea Brown Boveri) was founded as a result of the merger between the Swiss company BBC and the Swedish Asea Group. This new group comprised various motor factories in Switzerland, France, Sweden, Finland, Germany and Italy.

Closing down of locations

The production locations in Germany and France were closed soon after, and the existing product range was distributed to the remaining locations. In 2002, the production location in Birr, Switzerland, where new serial motors were produced, was closed.

All sources of supply

The electric motor service, however, remained in Birr, encompassing a wide range of service offers from the reconstruction of existing motors to the design of new special machines.

2012 – Relocation

ABB’s sale of its power plant sector to Alstom also affected the factory in Birr. This was not a long-term solution, and in 2012, the former motor factory moved into the newly built premises in Kleindöttingen.

Location – Kleindöttingen

The factory in Kleindöttingen covers a surface area of 6000 m2 and was fully equipped with state-of-the-art technology and systems in 2012.

State-of-the-art technology and systems

This includes, among others, a modern, stand-alone electric motor test bay, a rotor balancing plant, a large Vacuum Pressure Impregnation system, three burnout and drying chambers, a cleaning and spraying plant, winding and punching machines as well as additional infrastructure.

2018 Transition from ABB Switzerland to Birr Machines Ltd.
The newly founded company Birr Machines Ltd. under the leadership of experienced former ABB engineers and drive specialists took over the motor & service factory in Kleindöttingen.
At the center of the new company are our customers, whom we support with passion and competence.
