Joining electric motors

Joining by induction: MF generators by eldec ensure process reliability

Induction heating from EMAG eldec ensures reliability and that heat is distributed evenly in the joining processes – e.g. in the production of electric motors for power steering in cars. 

Electric motors for power steering: Fast production processes with EMAG eldec

Small components, high precision – this sums up the challenge of many applications in the production of electric motors. The thermal joining of the housing with the stator of an electric motor used in the power-assisted steering of a car is a good example: First, the small housing needs to be heated to a specific temperature. It expands, and the stator can be joined. As it cools down, the housing contracts again and makes a form-fitting, tight connection.

Manufacturers of this key power steering component rely on induction heating technologies from EMAG eldec. The process uses custom inductors and MF generators with 25 kW power. The process is fast, energy-efficient, and safe: The inductor dips into the housing and heats a specific area to about 160 °C in only a few seconds. Then the actual joining step takes place.

Customers benefit from EMAG eldec’s expertise in induction even at an early stage: If desired, the specialists support the design of the production process, conduct trials, and use state-of-the art simulation software during the development of the inductor. The end result is an electric motor perfect for the desired process.
