Abstract: Multi-motor vibratory transmission systems have been wide used
in large vibratory machines, and four-motor linear vibratory
machine is one typical equipment of them. Under non-forcible
synchronization condition zero-phase synchronization of the
machine is non-stationary and π-phase synchronization is stable.
Under half-forcible synchronization condition in which only one
motor is controlled being synchronous to another, only lag
synchronization near zero-phase synchronization can be realized.
Both of the characteristics have never been revealed with
classical theory quantitatively. The problems solved by means
of establishing an electromechanical coupling mathematical model
of the system and numerical analysis of the starting processes.
Key words: Vibratory
transmission Electromechanical coupling Self-synchronization
