Converters for High-Speed Machining

Drive controllers for high-speed applications by SIEB & MEYER

Powerful frequency converters, which provide high rotating field frequencies, are essential for the operation of the high-speed spindles used in modern machine tools. In addition, the usually small rotor volume in the field of high-speed processing requires a highly precise motor control with low losses to prevent excess temperatures. The converters by SIEB & MEYER offer exactly that – with innovative control technology, high energy efficiency and optimized overall efficiency.

Whether used in a large-sized machine tool or in the smallest space of a CAD/CAM milling machine: solutions by SIEB & MEYER guarantee maximum power at minimum heat development. The converters support sensorless and sensor-based operation of synchronous and asynchronous motors with speeds up to 240,000 min⁻¹ – configurable via the intuitive software drivemaster2.

  • Drilling, Routing

    High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed.

  • Grinding

    Grinding applications have a special position in the field of machine tools. Internal grinding applications, for example, require sensorless operation of asynchronous and synchronous spindles up to 250,000 rpm.

  • Dressing

    For dressing applications, it is essential to keep the spindle temperature low: a temperature increase in the spindle causes a longitudinal growth and therefore a shift of the tool position.

  • Dental CAD/CAM

    Small CAD/CAM routing machines are used, for example, in dental laboratories for jewelry making or engraving works as well as for producing advertising displays.

  • Wafer dicing

    High-speed dicing spindles are the key components in machines for microchip separation – the so-called wafer dicing.

  • Wastewater Treatment

    Due to their design, a large number of technologies in the field of waste energy usage or mechanical energy storage require high-speed motors and generators

  • Atomizer

    Rotary atomization processes, e.g. applied for the production of milk powder or flue gas treatment, require high circumferential speeds. Therefore, it is necessary to use matching high-speed motors instead of low-speed standard motors.

  • Polygon Scanners

    Polygon scanners are based on special optics and operate, for example, sorting machines. Up to now, manufacturers had to install encoders to run these scanners with a high speed stability.
