Mechanical power control unit for multi-motor drive of printing machine - has several electrical motors coupled to gear drive at different feed places

摘要

The gear wheel drive consists of a number of gear wheels permanently in engagement, and each electric motor is assigned an incremental rotation transmitter. The outputs of adjacent rotation transmitters (8) are respectively connected with the inputs of a phase measuring system (9). The outputs of the phase measuring system are connected with a regulating unit (10). The regulating unit (10) works in conjunction with regulating elements (11), for the output of the individual electric motors (6). ADVANTAGE - Electric motors are so controlled that uniform loading of gear train of gear unit driving printing machine is ensured.
