Modular Induction Generators

With the modular induction generators, Kendrion has developed a scalable system consisting of a controller and up to seven generator modules. These supply the inductors with optimally adjusted power. The controller is integrated into the machine control system via a fieldbus such as PROFINET, ETHERCAT CANopen, or another fieldbus system.

The controller for the modular and inductive heating system is a fieldbus-compatible device for controlling up to seven power output stages that are directly connected to each other via the module bus. Extensive diagnostic options as well as optional integrated inputs and outputs, enable fast commissioning. 

The modular induction generators are operated on the three-phase AC network with a voltage of 400 V and a frequency of 50/60 Hz. The mains current is rectified and fed to the DC link, from which the inductors are supplied individually . They are activated by the controller of the modular heating system. The control range from 0% to 100% can be selected individually for each channel. By using state-of-the-art semiconductor switches, the output stages achieve high efficiencies of approx. 98% at operating frequencies up to 25 kHz.

The modular induction generators are available in various configurations tailored to the different Kendrion inductors and the power requirements of the respective application:

• The 4-channel induction generator is designed to supply up to 4 induction coils (inductors) with an output of up to 6.5 kW each.
• The 6-channel induction generator is designed for applications with a large number of inductors and a power output of up to 3 kW per induction coil.

In addition to the modular induction generators, Kendrion also provides customized solutions. Our customer-specific induction heating systems are designed precisely to your heating requirements and additionally integrate functionalities you need.

The inductors are tailor-made to fit your tools. These are often roller inductors that are permanently installed inside rollers, rolls, and cylinders. Alternatively, we speak of surface inductors, in which induction coils heat tools over a wide area. The heat is transferred without contact via a magnetic field.
