A rotating field machine, in particular an electric motor with a stator and a rotor, is configured with a motor control for controlling the rotation and the rotational speed n of the rotor of the rotating field machine, wherein the motor control integrally includes an oscillation sensor system in order to acquire actual measurement values of oscillations of the rotating field machine depending on the rotational speed n.

Device for continuous oscillation monitoring during rotating field machine operation

A ventilator having a rotor is mounted in a rotatable manner around an axis of rotation. The rotor includes a plurality of blade-like rotor blades arranged around the axis of rotation. The ventilator includes a sensor device for detecting an object approaching one of the plurality of rotor blades, and a control device that receives signals from the sensor device. The control device extrapolates a trajectory of the object from a position x and a speed v of the object, and adjusts an angular position or rotational speed n of the rotor to allow the object to continue moving along its trajectory without colliding with one of the plurality of rotor blades.

A method for determining the positions of a number of fans (V) for generating an air flow in a preferably enclosed space. The fans (V) have an acceleration sensor to determine their position. The fans (V) are arranged in rows (R, R, . . . , R) and columns (S, S, . . . , S). At least the position (i, j) of one fan (V) is known.
