A method for controlling at least one radial blower in a cooling system. The radial blower includes a housing in which a shaft is rotationally mounted, which receives at least one impeller wheel of a compressor at one end, which is secured to the housing. The housing includes at least one radial bearing and at least one axial bearing via which the shaft is rotationally mounted in the housing. The radial blower also includes a motor which is driven by a rotor and a stator and which drives the shaft. By means of at least one laser Doppler vibrometer assigned to the shaft, operating points of the shaft are detected and forwarded to a controller for determining an operating status of the radial blower.

Method for controlling at least one radial blower in a cooling system, and radial blower

A radial blower, in particular for a cooling machine, comprising a housing in which a shaft is rotationally mounted, which receives at least one impeller wheel of a compressor at one end, which is secured to the housing, comprising at least one radial bearing and at least one axial bearing via which the shaft is rotationally mounted in the housing, and comprising a motor driven by a rotor and a stator and provided between the first and the second radial bearing, wherein at least one channel having a pressure connection for a pressure medium to be supplied is provided in the housing, which channel feeds into a rotor space formed between the shaft and the housing and extending from the impeller wheel to the radial bearing or axial bearing, which is provided next to the impeller wheel.
