FIELD: mining machinery.
SUBSTANCE: invention relates to mining machinery DC drives operated at lower temperatures and variable loads. Proposed adjustment method comprises monitoring control system malfunction via determination of electric drive time constants and generation of feedback signal, which allows decreasing motor RPM in case control system malfunctions. Proposed device incorporates drive component active parametre pickups, data acquisition and processing device, indication device and operator electronic key.
EFFECT: reduced dynamic loads at lower temperatures and control system malfunction.
