Abstract: Multiple temperature-control process for stators (7) and rotors of electric motors and components consisting of materials with different magnetic properties by means of a triplex furnace (1) for the quick, efficient, and uniform heating-up of preferably tubular components such as stators (7), wherein the magnetic parts of a component are primarily heated up by means of induction and at the same time non-magnetic parts of the same component are primarily heated up by means of infrared radiation, and at the same time and subsequently secondary heating takes place by means of convection, in particular by passive heating elements (10), which serves for finely adjusting the target temperature and for maintaining it.

Abstract: A method and a device for transporting and driving components and tools, such as rotors and stators for manufacture, includes a component carrier with at least two chain sprockets rigidly connected to the component carrier. The chain sprockets engage four driven chains to move, rotate and swivel or rotated to a limited extent the component carrier. With the upper chain and lower chain moving at the same speed and in opposite directions of movement, the component carrier rotates on the spot, with the two chains moving at the same speed and in the same direction of movement, the component carrier moves without rotation at the chain speed in the direction of movement, and with the chains moving at different speeds and in the same or different directions of movement, a plurality of combinations of direction of rotation, direction of movement, transport speed and rotational speed can be achieved.
