Introduction: On the phylogeny of plastic and mechanical drive, ever had used dc timing, electromagnetism timing in succession, but used communication frequency control already increasingly at present. Generally speaking, plastic film machinery has the following to the requirement of transmission system: (1) can be flowing inside certain limits timing, through adjusting advocate the product that the rotate speed of electric machinery, drawing electric machinery will come to produce different specifications; (2) is started, stop smooth, because plastic machine is constant torsion load, start, stop to be able to avoid too big mechanical impact smoothly, also can reduce the rejected product in the process that start on the other hand; (3) electric machinery needs only way to move only; (4) performance is steady, the job is reliable. To achieve above goal, on the phylogeny of plastic and mechanical drive, ever had used dc timing, electromagnetism timing in succession, but used communication frequency control already increasingly at present. Integrated and old frequency conversion uses experience, the end that uses transducer includes: (1) managing the sources of energy: The moving V/f curve according to transducer is knowable, transducer is constant torsion output, compare with photograph of other timing system, average and managing electric energy amounts to 30% above, energy-saving effect moves in low speed more remarkable; (2) improves product quality: Frequency control performance is quite steady; (3) lessens the to electrified wire netting impact when starting, the electric current that start is controallable do not form pair of voltage to pound inside rated electric current; (4) lessens the to machinery impact when starting, flowing start the service life that can prolong machinery; (5) satisfies requirement of stepless speed regulation, timing simple, operation is convenient; (6) protection function is powerful.
