Inventia are ca obiect un dispozitiv pentru comanda unui vibrator pentru piloti, realizat cu traductoare si dispozitive de prescriere pentru momentul static al maselor neechilibrate, turatia acestora si pentru puterea absorbita de motorul de actionare. Semnalele preluate de la traductoare sunt preluate de un bloc electronic de comanda care le prelucreaza în binar, le converteste apoi în semnal analogic si determina functionarea unor blocuri de actionare, care asigura functionarea motorului asincron si, implicit, a vibratorului în limitele parametrilor prescrisi.The invention relates to a device for controlling a vibrator for pilots, made with transducers and prescription devices for the static moment of unbalanced masses, their speed and the power absorbed by the drive motor. The signals taken from the transducers are taken over by an electronic control block that processes them in the binary, then converts them into an analog signal and determines the operation of some actuation blocks, which ensure the operation of the asynchronous motor and, implicitly, of the vibrator within the prescribed parameters.
