ABSTRACT:
The invention relates to method and apparatus for controlling the powering of electric drive motors (8) of a group of at least two machines (2, 3, 4), the motors operating in periodic motions, wherein the periodic motions are mutually coordinated in a manner so as to control a parameter which is representative of the operations of the machines. Parameters may include one or more of the sum of the electric power applied to the drive motors, the magnitude of the noise level generated by the machines and machine-caused vibrations. The drive motors of one machine may be controlled as a function of the periodic motion of the drive motor of the other machine, and power applied to one drive motor may be applied as a function of a mutually related drive motion of the machines.
