Line motor drives a piece of heald frame, it is difficult to accomplish Complete Synchronization, produces Additional interference, electric current dramatically increases.It is difficult to the reason for synchronous
First, even if linear electric motors are produced by same parameters, performance difference is necessarily also had between two；Two be due to the lifting of heald frame
Speed is of a relatively high, stroke is short, or even up to per second 7 times, therefore even if is synchronous to the driving instruction that two motors are sent
, cause two motors to interfere because its mechanical response time is variant, increase running resistance, and then cause heald frame and
Balanced controls are actually not Complete Synchronization motion, and this will increase the resistance of motion and increase mechanical disorder, can greatly reduce
Equipment life, or even be difficult to reach practical purpose.Occurs new technical problem relative to traditional up-down mode；For
This asynchronous problem, machinery forced synchronization can also be designed to, but in this operating condition, electric current is significantly maximum, because
It is synchronously presentation for mechanical forced, internal electromagnetic force does not have synchronously, and generation interferes, and consumes more electric energy.
In addition, the linear electric motors that market can be chosen now, all do not have guider typically, even if choosing proximity type
Number linear electric motors, the linear motor rotor vertically used is also what cantilever connected with line slideway, Resultant force caused by mover,
Go out between force to have one section of size distance relative to the sliding block of line slideway, form a tilting moment, this torque not only can
Increase the abrasion of line slideway, it is necessary to increase after balanced controls could eliminate its statical moment and the imbalance of moment of inertia
Fruit, such equipment just necessarily increase complexity.
