Induction generators - Import export

The induction generator module is designed to supply up to 6 induction coils (inductors) with a power of up to 3 kW each. The device operates on the three-phase mains with a voltage of up to 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 individually supplied. The output power is controlled via the Kendrion controller of the modular industrial heating system. The setting 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, at working frequencies up to 25 kHz.

The induction generator is designed to supply up to 4 induction coils (inductors) with a power of up to 7.5 kW each. The device operates on the three-phase mains with a voltage of up to 400 V and a frequency of 50/60 Hz.

In addition to system monitoring, the controller can also control or regulate the individual output channels of all power modules. Actual temperature values can be delivered directly via CAN fieldbus or provided by a higher-level controller e.g. a PLC. ; PROFINET Fieldbus interface; Independent control of up to 7 induction generators; System monitoring, temperature control; Integrated I/Os and CAN system bus

An alternative to conductive heat sealing is contact induction sealing, which is particularly suitable for sealing demanding container materials such as e.g. glass, metal or ceramic. An electromagnetic field is built up by a generator via an induction coil that is housed in the sealing head. The molecules of the aluminum foil are set in rotating vibrations, creating heat that is used for the sealing process. Our sealing machines PolySeal Vario PN and PolySeal Vario Twin as well as all fully automatic sealing systems can be equipped with induction technology.

In addition to purely switching sensors, your sensor specialist EGE also offers you inductive proximity switches with analogue output for measuring tasks. The analogue signal is proportional to the approximation of the metal part. This sensor is also available in a version up to 160° C. The proximity sensor is based on the proven inductive principle: When metallic objects come close, the resonant circuit of a coil is dampened through induction and an analogue signal generated from it. Analogue inductive are e.g. suitable for the double occupation control of metal plates, for the tensioning control of wire or for monitoring metallic brake pads.

The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.

Earthing Clear tasks relating to earthing arise from relevant norms and regulations: DIN VDE 0101: 9.3.4 Measuring for earthing of operating media and systems All exposed metal parts of electrical operating media which are not part of the operational power circuit (structures), which are part of the electrical network must be earthed.Insulated areas should be created in special cases. All metal parts which are not part of electrical operating media should be earthed, provided this is appropriate (e.g. due to accidental arcing, capacitive and inductive coupling). Betonbau generally realises this task through discretely-structured visible connections between the HPAS of the building and active plant components. This offers you the advantage of high process reliability and contributed to overall comprehension and verifiability for everyone. Reinforced concrete also offers enormous advantages in itself with regard to equipotential bonding and integration in earthing current circuits.

To achieve perfect induction heating processes depends on generators providing precisely the right amount of energy. With its CUSTOM LINE LF generators, eldec provides just the right solution for the low frequency range (2 to 8 kHz). Induction heating with tough generators “Customized” is the key word when it comes to delivering a perfect production solution in mechanical and systems engineering. This is particularly true for induction heating. The process needs to be configured accurately to produce the desired effect in the material. CUSTOM LINE generators by eldec are the ideal solution for delivering precisely the right amount of power and energy. The LF series (power: 50 to 500 kW, frequency: 2 to 8 kHz) is designed for lower frequencies.

TDS Induction Mixers draw powder, liquids or gases below their level into liquids and at the same time homogenise the contents of the container. The vacuum required for induction is generated in the mixing head. The machine is installed in the container from above by means of a flange or traverse. Alternatively, the TDS Induction Mixer can work on a lifting frame. The powder is inducted from the container and introduced under the fluid level by mixing it immediately and wetting. The mixing head generates the required negative pressure. Dust loads are prevented during the addition of powder by direct induction from the bag. Effective micro and macro mixing of the complete container contents with simultaneous addition of powder. Immediate wetting under fluid level. Complete mass transfer and homogeneity across all container levels via the jetstream mixing principle. In addition, liquids and gases can be inducted.
