A rotor () with a squirrel cage and permanent magnets () mounted on and distributed around the circumference of the rotor, including a core stack extending over the entire rotor region with longitudinally continuous rotor slots extending over the length of the core stack. The squirrel cage is constructed with cage bars disposed, and preferably cast, in the rotor slots; short circuit rings connect the cage bars at both end faces of the core; and the radius of the rotor region is reduced by at least the radial thickness of the magnets. The radius of rotor () is reduced over the entire length between short circuit rings () such that the radial height of cage bars () or cage webs () connected thereto is reduced. Also an electric motor or a radial pump having such a rotor, and methods of producing or operating such devices.

Method of making a squirrel cage rotor having reduced radius to accommodate permanent magnets

A device and a method for detecting deposits () on walls () that are covered by a medium, in which as sensor () is integrated in the wall (). A component () of the sensor () locally heats the medium in a region (), and the temperature of the medium around the component () is detected. The sensor () relays temperature measurement signals to an analysis unit (), where the degree of deposit formation is determined, e.g., by comparison with stored reference data.
