The mechanism provides automatic power down and stop the output shaft at two extreme positions (initial and final), signaling the end positions of the output shaft (far left and far right) by closing electrical circuits and visually, the fixation of the output shaft after power is removed. Electrо-mechanism consists of a housing, reducer, flange, contactless (brushless) motor with control unit, position sensor rotor, the sensor of the end position of the output shaft, plug connections of the power supply, terminals plating, mechanical position indicator output shaft. The power is electrically operated from a two wire power supply system direct current nominal voltage of 27 V. Reducer consists of two the planetary stages. When applying a control signal to the electrical mechanism from the object output the shaft starts to rotate. The alarm in the external circuit is given by the electrо-mechanism when the presence of power on it. To reduce coasting of the output shaft in the electrо-mechanism provided dynamic braking. The mechanism provides the following types of protection: - protection for the start; - protection from jamming; - protection against overheating of the control unit. The operation of each protection causes a complete stop of electrо-mechanism. At frequency of rotation of the shaft electrо-engine below acceptable since the launch, at the decline of frequency of rotation of the shaft electrо-motor below possible during work of electro-mechanism, when the temperature of the block control above the limit. The mode of operation of electrо-mechanism operated - repeated-brief: cyclic or impulsive. One cyclic operation corresponds to the rotation of the output shaft from one extreme position to the other and back with constant speed. One pulse corresponds to the trigger pulse enable at any direction of rotation duration from 0.2 to 1 s. Product Description popup.authors Кисенко Олександр Михайлович popup.nrat_date 2020-04-02 Close
