The drive portfolio suitable for this application includes IP65 asynchronous motors, synchronous motors with high protection class IP65 and IP67, and synchronous reluctance motors up to IE4 Super Premium efficiency class for the optimum performance and power requirements of your machine. The dedicated frequency inverters are designed for use in high temperature environments and equipped with dedicated cooling concepts and coated printed circuit boards. Our experience with the piecing process when starting rotor spinning machines ensures reduction of standstill times and manual labor required for these machines during start up.
