Abstract
The invention provides a sensorless servo driving system of a vulcanizing machine. The sensorless servo driving system is composed of a vulcanizing machine controller, a servo driver, a servo motor, an oil pump, an oil cylinder, a proportional pressure valve, a reversing valve, an overflow valve and fuel tanks. An output connector of the servo driver is electrically connected with the proportional pressure valve. A flow signal of the vulcanizing machine controller is electrically connected with the servo driver. An oil pressure signal of the vulcanizing machine controller is electrically connected with the servo driver. A signal comparator is arranged in the servo driver. Electric current and oil pressure signals output by the servo driver serve as signal comparison objects of the signal comparator. Operating modes of the servo driver are switched through the signal comparator. Due to the fact that no pressure sensors, speed sensors and correspondingly-matched circuits are needed, the stability of the sensorless servo driving system is remarkably improved, and the manufacturing cost of the system can be significantly reduced at the same time.
