Together with scientists from Karlsruhe Institute of Technology, KSB specialists developed a very compact 22-kW synchronous reluctance motor. Semiconductor technology facilitates the cooling management that ensures removal of heat emerging from the power electronics. The element’s volume could be reduced by 25 %, due to the integrated frequency inverter. The drive exists as prototype, which was built to demonstrate the potential of silicon carbide components in terms of higher motor ratings. While most of the standardised pumps operate at constant motor speed with an impeller, that has been mechanically trimmed for the desired operation point, this motor operates with a „virtually trimmed impeller“. Thus trimming is even possible after the pump set has been commissioned.
