Device fault detector feedback velocidadpara electronic engine controllers conti-nuous current

摘要

Device fault detector speed feedback for electronic regulators DC motors, characterized in that it comprises a detector circuit comprising two polarized operational amplifiers each respectively with a small positive or negative voltage in order to both directions of rotation engine control amplifiers which are commonly connected through a diode and in turn in the same communication connection to a shunt intended to connect through another diode to the appropriate means of preconditioning acting on the machine suitable predisposition based on the signal sent according to whether or not speed feedback signal from the corresponding media engine related, going in relation to said other secondary circuit this circuit like intended to receive the reference signal speed Establishe to for equine, whose output branch of the second circuit is connected to that of the former first to cancel dei same action on the means of preconditioning in the case of that reference velocity is zero in compliance stop command ; all so that if by anomalous circumstances, but not stop command disappears speed feedback in motor control concerned this device detects the abnormality by activating the safety means which are provided for this circumstance.
