Description
technical field [0001] The invention relates to an air motor speed regulation control technology, in particular to an air motor speed regulation system. Background technique [0002] The working medium of air motor is compressed air, and the change of pressure will affect its working characteristics. When the input air pressure is constant, its speed, torque, and power all change with the external load. This soft characteristic is the biggest feature of the air motor, and it is difficult to realize it by adjusting the speed of hydraulic transmission such as input flow or variable. Precise speed regulation of the air motor. At present, many engineering equipment are driven by air motors, and the speed of the driving object of the air motor is adjusted mechanically instead of the air motor. Contents of the invention [0003] In order to overcome the shortcomings of low precision and poor control effect existing in the existing air motor speed regulation technology, the pre...
